{{Close Relationships}}

'''Cohabitation''' is an arrangement where people who are not married, usually couples, live together. They are often involved in a [[Philosophy:Romance (love)|romantic]] or sexually [[Social:Intimate relationship|intimate relationship]] on a long-term or permanent basis. Such arrangements have become increasingly common in Western countries since the late 20th century, being led by changing social views, especially regarding [[Biology:Marriage|marriage]], [[Social:Gender role|gender role]]s and [[Religion:Religion|religion]].

More broadly, the term ''cohabitation'' can mean any number of people living together. To "cohabit", in a broad sense, means to "coexist".<ref name=oxford>{{cite web|url=http://www.oxforddictionaries.com/definition/english/cohabit?q=cohabitation#cohabit__19|archive-url=https://web.archive.org/web/20140809025337/http://www.oxforddictionaries.com/definition/english/cohabit?q=cohabitation#cohabit__19|url-status=dead|archive-date=9 August 2014|title=Definition of cohabit|work=oxforddictionaries.com}}</ref> The origin of the term comes from the mid 16th century, from the Latin ''cohabitare'', from co- 'together' + habitare 'dwell'.<ref name=oxford/>

Today, cohabitation is a common pattern among people in the Western world.

In Europe, the Scandinavian countries have been the first to start this leading trend, although many countries have since followed.<ref>{{cite web |author1=Turid Noack |author2=Eva Bernhardt |author3=Kenneth Aarskaug Wiik |author4=Torkild Hovde Lyngstad |title=The realization of marriage plans among cohabiting couples in Scandinavia |url=http://paa2011.princeton.edu/papers/110852 |access-date=11 February 2019 |publisher=[[Organization:Princeton University|Princeton University]] |archive-date=22 September 2020 |url-status=dead |archive-url=https://web.archive.org/web/20200922163100/https://paa2011.princeton.edu/papers/110852}}</ref> Mediterranean Europe has traditionally been very conservative, with religion playing a strong role.

In Central and Eastern Europe, during the late 1980s and early 1990s, there were major political changes, such as the fall of Communist governments. These societies entered a new era of increased social freedom, less rigid rules, and less authoritarian governments. They interacted with Western Europe and some became members of the European Union. As a result, the patterns of family life have started to change: marriage rates have declined, and marriage was postponed to a later age. Cohabitation and births to unmarried mothers increased, and in some countries the increase was very quick.<ref>{{cite journal |vauthors=Thornton A, Philipov D |title=Sweeping Changes in Marriage, Cohabitation, and Childbearing in Central and Eastern Europe: New Insights from the Developmental Idealism Framework |journal=European Journal of Population |volume=25 |issue=2 |pages=123–156 |year=2009 |pmid=19498956 |pmc=2690230 |doi=10.1007/s10680-009-9181-2 }}</ref>

===Effect on children===

In 2001, researchers compared teenage children in the United States living in a cohabiting household (a single mother and her boyfriend who was not related to the teenager) against peers in single-parent households.

==Effects on marriage and family life==

===Likelihood of split===

Conflicting studies on the effect of cohabitation on subsequent marriage have been published. In countries where the majority of people disapprove of unmarried individuals living together, or a minority of the population cohabits before marriage, marriages resulting from cohabitation are more prone to divorce. But in a study on European countries, those where around half of the population cohabits before marriage, cohabitation is not selective of divorce-prone individuals, and no difference in couples that have cohabited before and after marriage is observed.<ref name="pmid16889125">{{cite journal |vauthors=Liefbroer AC, Dourleijn E |s2cid=13210179 |title=Unmarried cohabitation and union stability: testing the role of diffusion using data from 16 European countries |journal=Demography |year=2006 |volume=43 |issue=2 |pages=203–221 |pmid=16889125 |doi=10.1353/dem.2006.0018 |doi-access= free}}</ref><ref>{{cite journal |url=http://econpapers.repec.org/article/uwpjhriss/v_3a39_3ay_3a2004_3ai_3a2_3ap523-535.htm |author=Svarer, Michael

In 2002, the CDC found that for married couples the likelihood percentage of the relationship ending after five years is 20%, for unmarried cohabitators the likelihood percentage is 49%.

A follow-up survey by the researches of over 1,000 married men and women married in the past 10 years found those who moved in with a lover before engagement or marriage reported significantly lower quality marriages and a greater possibility of a separation than other couples.<ref name="pmid19203165">{{cite journal |vauthors=Rhoades GK, Stanley SM, Markman HJ |title=The pre-engagement cohabitation effect: a replication and extension of previous findings. |journal=J Fam Psychol |year=2009 |volume=23 |issue=1 |pages=107–111 |pmid=19203165 |doi=10.1037/a0014358 |pmc=5956907}}</ref>

Another 2004 study of 92 couples linked communication to cohabitation and instability. They found that married couples who cohabited before they were married had more negative problem-solving and communication skills. They also found that those who had cohabited expressed more (verbal) aggression throughout their conversations. This negative communication could be contributing to the cohabitation effect and causing a larger amount of marital instability.<ref>{{Cite journal |last1=Cohan |first1=Catherine L. |last2=Kleinbaum |first2=Stacey |date=February 2002 |title=Toward a Greater Understanding of the Cohabitation Effect: Premarital Cohabitation and Marital Communication |journal=Journal of Marriage and Family |language=en |volume=64 |issue=1 |pages=180–192 |doi=10.1111/j.1741-3737.2002.00180.x |issn=0022-2445}}</ref>

The researchers from Denver suggest that relationships with pre-engagement cohabitation "may wind up sliding into marriage",<ref name="telegraph.co.uk"/> whereas those that only cohabit post engagement or marriage make a more clear decision.

An analysis of data from the CDC's [[Social:National Survey of Family Growth|National Survey of Family Growth]] data from 1988, 1995, and 2002 suggests that the positive relationship between premarital cohabitation and marital instability has weakened for more recent birth and marriage cohorts, as the total number of couples cohabiting before marriage has increased.<ref name="pmid20879685">{{cite journal| vauthors=Reinhold S| title=Reassessing the link between premarital cohabitation and marital instability| journal=Demography| year=2010| volume=47| issue=3| pages=719–733| pmid=20879685| doi=10.1353/dem.0.0122| pmc=3000053}}</ref>

Later CDC work found that between 2002 and 2006-2010, the number of couples in opposite-sex cohabiting relationships increased from 9.0% to 11.2% for women, and from 9.2% to 12.2% for men.<ref>{{cite web |url=https://www.cdc.gov/nchs/nsfg/abc_list_c.htm#chabitation

Drawing on the 2006–2008 data, [[Organization:Princeton University|Princeton University]] researchers examined whether and to what extent variation in premarital cohabitation experiences influence marital stability. They found that the relationship between cohabitation and marital instability is complex and depends in part on marriage cohort, race/ethnicity, and marriage plans. Their analyses reveal that a 'cohabitation effect' exists only for women married prior to 1996, and that, until marriage plans are considered, there is no cohabitation effect among women married since 1996.<ref>{{cite web

Recent research from 2011 by the Pew Research Center has found that the number of couples that cohabit before marriage has increased. 44% of adults (and more than half of 30- to 49-year-olds) say they have cohabited at some point. Nearly two-thirds of adults who ever cohabited (64%) say they thought about it as a step toward marriage. The report also notes a trend toward rising public acceptance of cohabiting couples over the years. Most Americans now say the rise in unmarried couples living together either makes no difference to society (46%) or is good for society (9%).<ref>{{cite web

Regarding cohabitation as a fertility factor, a large survey in the United States came to the result that married women had an average of 1.9 children, compared to 1.3 among those cohabiting. The corresponding numbers for men were 1.7 and 1.1, respectively.

===Financial effects===

In the United States, married couples that submit a combined tax return may face a [[Social:Marriage penalty|marriage penalty]], where tax credits for low-income single earners are not applied to the combined income.
In October 1998, Senate GOP leader Trent Lott decided to pull a bill to abolish "the [[Social:Marriage penalty|marriage penalty]], which in the tax code reflects the fact that married couples who both work for wages frequently pay more in taxes than if they earned the same amount of income but weren't married. And the more equal the incomes of the couple, the steeper the marriage tax penalty."<ref name="americanvalues.org">{{cite news |author=Wade Horn |date=October 20, 1998 |work=The Washington Times |via=Institute for American Values |url=http://www.americanvalues.org/html/mp8.html |title=Government Punishes Marriage, Pushes Cohabitation |access-date=20 March 2012 |archive-url=https://web.archive.org/web/20110803200857/http://www.americanvalues.org/html/mp8.html |archive-date=3 August 2011 |url-status=dead}}</ref> The [[Finance:Earned income tax credit|earned income tax credit]] (EITC) is cash welfare for low-income workers, but the problem is the EITC is not for married couples because they have to combine their wages, which again leads to "the marriage penalty". If couples do not get married then their wages do not have to combine and the EITC in a way is "paying for" low-income couples not to marry. Opponents of cohabitation believe that some cohabiting couples choose not to marry because they would suffer a tax penalty.<ref name="americanvalues.org"/>

Despite the perceived disincentive to marry that the EITC provides, cohabiting couples suffer many financial losses as their unions are not recognized with the same legal and financial benefits as those who are legally married. These financial penalties can include the costs of separate insurance policies and the costs of setting up legal protections similar to those that are automatically granted by the state upon marriage.<ref>{{Cite web |title=Why Marriage Makes Financial Sense |website=Investopedia |url=https://www.investopedia.com/financial-edge/0412/why-marriage-makes-financial-sense.aspx |access-date=2022-08-07 |language=en}}</ref>

===No effect===

A conflicting study, published by the National Center for Health Statistics, with a sample of 12,571 people, concludes that "those who live together after making plans to marry or getting engaged have about the same chances of divorcing as couples who never cohabited before marriage".<ref>{{cite news|author=Jayson, Sharon |date=14 October 2010 |title=Report: Cohabiting has little effect on marriage success |work=USA Today |url=https://www.usatoday.com/news/health/2010-03-02-cohabiting02_N.htm}}</ref>

Additionally, William Doherty, a professor in the Department of Family Social Science at the University of Minnesota has remarked that in his research he has found that "committed cohabiting relationships seem to confer many of the benefits of marriage".<ref>{{cite web |url=http://www.unmarried.org/experts.html#cohabitation |title=The Experts Speak |publisher=Alternatives to Marriage Project |website=Unmarried.org |access-date=10 November 2012 |url-status=dead |archive-date=7 February 2013 |archive-url=https://web.archive.org/web/20130207003408/http://www.unmarried.org/experts.html#cohabitation}}</ref>

A 2003 study by the Australian Institute of Family Studies found that "The differences in measured outcomes for those from direct and indirect marriages appear to be entirely attributable to other factors."<ref>{{cite journal|title=Premarital cohabitation and subsequent marital stability

Buhman'' that the portions of Utah's anti-[[Religion:Polygamy|polygamy]] laws which prohibit multiple cohabitation were unconstitutional, but also allowed Utah to maintain its ban on multiple marriage licenses.<ref>{{cite news |last=Schwartz |first=John |date=14 September 2013 |title=A Law Prohibiting Polygamy is Weakened |url=https://www.nytimes.com/2013/12/15/us/a-utah-law-prohibiting-polygamy-is-weakened.html?nl=todaysheadlines&emc=edit_th_20131215&_r=0 |newspaper={{wipe|The New York Times}} |access-date= 13 January 2014}}</ref><ref>{{cite web |last=Mears |first=Bill |date=14 December 2013 |url=http://www.cnn.com/2013/12/14/justice/utah-polygamy-law/ |title='Sister Wives' case: Judge strikes down part of Utah polygamy law |publisher=CNN |work=CNN.com |access-date= 13 January 2014}}</ref><ref>{{cite news |last=Stack |first=Peggy Fletcher |date=14 December 2013 |url=http://www.sltrib.com/sltrib/news/57264020-78/church-polygamy-mormon-says.html.csp |title=Laws on Mormon polygamists lead to win for plural marriage |newspaper=The Salt Lake Tribune |access-date=13 January 2014}}</ref> This decision was overturned by the United States Court of Appeals for the Tenth Circuit, thus effectively recriminalizing polygamy as a felony.<ref>{{Cite news |url=https://www.reuters.com/article/us-utah-polygamy-sisterwives-idUSKCN0X82AJ |title=Appeals court restores Utah's polygamy law in 'Sister Wives' case |work=Reuters |date=11 April 2016}}</ref> In 2020, Utah voted to downgrade polygamy from a felony to an infraction, but it remains a felony if force, threats or other abuses are involved.<ref>{{Cite news |url=https://www.nytimes.com/2020/05/13/us/utah-bigamy-law.html |title=Utah Lowers Penalty for Polygamy, No Longer a Felony |newspaper=The New York Times |date=13 May 2020 |last1=Hauser |first1=Christine}}</ref> Unlawful cohabitation, where prosecutors did not need to prove that a marriage ceremony had taken place (only that a couple had lived together), had been a major tool used to prosecute polygamy in Utah since the 1882 Edmunds Act.<ref>{{cite book |first=Jessie L. |last=Embry |contribution=Polygamy |contribution-url= http://www.uen.org/utah_history_encyclopedia/p/POLYGAMY.html |editor-last=Powell |editor-first=Allan Kent |year=1994 |title=Utah History Encyclopedia |location=Salt Lake City, Utah |publisher=University of Utah Press |isbn=978-0874804256 |oclc=30473917 |access-date=13 January 2014 |url-status=dead |archive-date=17 April 2017 |archive-url= https://web.archive.org/web/20170417163937/http://www.uen.org/utah_history_encyclopedia/p/POLYGAMY.html}}</ref>

====Latin America====

Cohabitation in Latin America is becoming more common. Indeed, although this is a largely Roman Catholic region, it has the highest rates of non-marital childbearing in the world (55–74% of all children in this region are born to unmarried parents).<ref name="sustaindemographicdividend.org">{{cite web |url=http://sustaindemographicdividend.org/articles/international-family-indicators/global-childrens-trends |title=Global Children's Trends |work=The Sustainable Demographic Dividend |access-date=10 November 2012}}</ref> In Mexico, 18.7% of all couples were cohabiting {{as of|2005|lc=y}}.

As of 2000, in {{wipe|Argentina}} 58% of births were to unmarried women.<ref name="sustaindemographicdividend.org"/>{{efn|The most recent data for Argentina are from 2000 because after 2000, Argentina's Ministry of Health changed to publishing births as mother living with a partner or not (including married or cohabiting) rather than as marital and nonmarital.}}
The percentage of births outside marriage has increased throughout Latin America during the past decades, and there is also a relation to place of residence: women living in the capital city are more likely to have children outside marriage than those living in other parts of the country.<ref>{{cite conference |author1=Teresa Castro Martín |author2=Clara Cortina |author3=Teresa Martín García |author4=Ignacio Pardo |title=La fecundidad no matrimonial en América Latina: indicadores y análisis comparativos a partir de datos censales |trans-title=Non-marital fertility in Latin America: indicators and comparative analyzes based on census data |conference=IX Jornadas de Investigación de la Facultad de Ciencias Sociales, UdelaR, Montevideo, 13-15 de setiembre de 2010 [IX Research Conference of the Faculty of Sciences Sociales, UdelaR, Montevideo, September 13-15, 2010] |language=es |url=http://www.fcs.edu.uy/archivos/Mesa_46_Castro%20Mart%C3%ADn%20et%20al.pdf |access-date=14 June 2015 |archive-url=https://web.archive.org/web/20150402091547/http://www.fcs.edu.uy/archivos/Mesa_46_Castro%20Mart%C3%ADn%20et%20al.pdf |archive-date=2 April 2015 |url-status=dead}}</ref> Recent data shows figures for non-marital childbearing to be 74% for Colombia, 69% for Peru, 68% for Chile, 66% for Brazil and 55% for Mexico.<ref name="sustaindemographicdividend.org"/><ref>{{Cite web |last=Vieira |first=Joice Melo |date=2013 |title=The Evolution of Births Outside of Marriage, Paternal Recognition and Children's Rights in Brazil |url=http://paa2013.princeton.edu/papers/131703 |access-date=1 August 2022 |website=Population Association of America: 2013 Annual Meeting Program |format=PDF |archive-date=4 March 2016 |archive-url=https://web.archive.org/web/20160304084714/http://paa2013.princeton.edu/papers/131703 |url-status=dead}}</ref>

===Asia===
====Nepal====
In Nepal, living together is socially acceptable only after marriage.<ref>{{cite journal|author1=Marcantonio Caltabiano |author2=Maria Castiglioni |date=March 2008 |title=Changing Family Formation in Nepal: Marriage, Cohabitation and First Sexual Intercourse |journal= International Family Planning Perspectives |volume=34 |issue=1 |pages=30–39 |doi=10.1363/3403008 |pmid=18440915 |doi-access=free }}</ref> However, cohabitation is an emerging trend in urban areas of Nepal. Reports have shown that there may be significant number of unmarried couples cohabiting in cities, especially in the capital, [[Place:Kathmandu|Kathmandu]]. Even when unmarried couples cohabit they either prefer to remain anonymous or pose themselves as a married couple.<ref>{{cite web |url=http://xnepali.net/movies/living-together-without-marriage-new-trend-in-nepali-society/|title=Living Together Without Marriage – New Trend in Nepali Society |work=Nepali Movies, Nepali Films|date=27 June 2010|access-date=22 August 2015}}</ref> Cohabitation is not recognized by the law of Nepal and there is no special provision to secure the right of cohabitants in Nepalese law.

====Bangladesh====
In Bangladesh, there are no laws prohibiting cohabitation but it is still socially unacceptable. However, cohabitation is becoming more common in urban areas due to western influence.<ref>{{Cite web|author=Ishrat Hasan |date=10 August 2017 |title=Your Legal Advisor |url=https://www.observerbd.com/details.php?id=88934 |website=The Daily Observer}}</ref> An unmarried couple may feel immense pressure to marry by their family, and will probably choose to live as if they were married and, if exposed, can be expelled from housing or university.

====China====
In China, cohabitation has become popular among young adults. One study shows that the cohabitation rate before first marriage was over 20% for those born after 1977.<ref>{{cite journal |author1=Yu Jia |author2=Yu Xie |date=December 2015 |title=Cohabitation in China: Trends and Determinants |journal=Population and Development Review |volume=41 |issue=4 |pages=607–628 |doi=10.1111/j.1728-4457.2015.00087.x |pmid=30416225 |pmc=6226097 |url=https://scholar.princeton.edu/sites/default/files/yuxie/files/pdr414.yu_.pp607-628.pdf |access-date=22 April 2019 |archive-date=10 March 2023 |archive-url=https://web.archive.org/web/20230310081020/https://scholar.princeton.edu/sites/default/files/yuxie/files/pdr414.yu_.pp607-628.pdf |url-status=dead }}</ref> Another recent study shows that cohabitation increases the divorce likelihood for those married in the early-reform period, but premarital cohabitation has no effect on divorce for those married in the late-reform period in China.<ref>{{cite journal |doi=10.1111/jomf.12419 |title=Premarital Cohabitation and Marital Dissolution in Postreform China |author=Yongjun Zhang |journal=Journal of Marriage and Family |volume=79 |issue=5 |pages=1435–1449 |year=2017 |url=http://osf.io/gsjf9/}}</ref>

====India====
Cohabitation in India had been taboo in traditional Hindu and Muslim societies. However, this is more acceptable between upper classes in large cities, but is not often found in rural areas and smaller towns which are more social conservative. '''Live-in''' relationships are legal in India. Recent Indian court rulings have ascribed some rights to long-term cohabiting partners. Female live-in partners have economic rights under Protection of Women from Domestic Violence Act 2005 subject to following conditions as laid by Honourable Supreme Court of India in case of ''D. Velusamy v D. Patchaiammal'':

# The couple must hold themselves out to society as being akin to spouses.
# They must be of legal age to marry.
# They must be otherwise qualified to enter into a legal marriage, including being unmarried.
# They must have voluntarily cohabited and held themselves out to the world as being akin to spouses for a significant period of time.

On 12 June 2020, the Uttarakhand High Court stated in the case of Madhu Bala v. State of Uttarakhand and others (Habeas Corpus Petition No. 8 of 2020) that consensual cohabitation between two adults of the same-sex is legal.<ref>{{Cite web |title=Indian High Court Reaffirms Same-sex Couples' Right to Cohabitation |url=https://www.humanrightspulse.com/mastercontentblog/indian-high-court-reaffirms-same-sex-couples-right-to-cohabitation |access-date=2022-08-07 |website=Human Rights Pulse |date=9 August 2020}}</ref>

====Indonesia====
In Indonesia, an Islamic penal code proposed in 2005 would have made cohabitation punishable by up to two years in prison, but failed to pass.<ref>{{cite news| url=http://news.bbc.co.uk/1/low/world/asia-pacific/4239177.stm | work=BBC News | title=Indonesia plans new morality laws | date=6 February 2005 | access-date=28 March 2010}}</ref> The practice is still frowned upon, and many low-end hotels and boarding houses have been raided by police for allowing unmarried couples to share a room.

====Japan====
In Japan, according to M. Iwasawa at the National Institute of Population and Social Security Research, less than 3% of females between 25–29 are currently cohabiting, but more than one in five have had some experience of an unmarried partnership, including cohabitation. A more recent Iwasawa study has shown that there has been a recent emergence of non-marital cohabitation. Couples born in the 1950s cohort showed an incidence of cohabitation of 11.8%, where the 1960s and 1970s cohorts showed cohabitation rates of 30%, and 53.9% respectively. The split between urban and rural residence for people who had cohabited is indicates 68.8% were urban and 31.2% were rural.<ref>{{Cite web |url=http://paa2006.princeton.edu/download.aspx?submissionId=61321 |title=Unmarried Cohabitation and Family Formation in Japan |date=September 23, 2005 |author1=Miho Iwasawa |author2=James M.

====Philippines====
In the {{wipe|Philippines}}, around 2.4&nbsp;million Filipinos were cohabiting {{as of|2004|lc=y}}. The 2000 census placed the percentage of cohabiting couples at 19%. The majority of individuals are between the ages of 20–24. Poverty was often the main factor in decision to cohabit.<ref>{{Cite web |url=http://www.gmanews.tv/wedding/tomarryornot.html |title=tomarryornot |author=Clarissa V.

Various factors such as economic crises and cultural and social changes in cities are reasons for the increase in the number of cohabitation in Iran. In other words, the emergence of [[Philosophy:Capitalism|capitalism]], the increase of job insecurity, the emergence of moral [[Philosophy:Liberalism|liberalism]], the revision of cultural traditions, the anonymity of people in cities, the elimination of the concepts and functions of neighborhoods, changes in family structures and the emergence of temporary relationships are among the major reasons for white marriage in Iran.<ref name=":1"/><ref name=yyyy/><ref name=LATimes/><ref name=a-45206118/><ref name=":2"/><ref>{{Cite web |title=برساخت اجتماعی ازدواج سفید |trans-title=The social construction of white marriage |website=پرتال جامع علوم انسانی |trans-website=Comprehensive humanities portal |language=fa |url=http://ensani.ir/fa/article/464341/%D8%A8%D8%B1%D8%B3%D8%A7%D8%AE%D8%AA-%D8%A7%D8%AC%D8%AA%D9%85%D8%A7%D8%B9%DB%8C-%D8%A7%D8%B2%D8%AF%D9%88%D8%A7%D8%AC-%D8%B3%D9%81%DB%8C%D8%AF |access-date=2023-02-04 |url-status=dead |archive-date=2023-02-04 |archive-url=https://web.archive.org/web/20230204201437/http://ensani.ir/fa/article/464341/%D8%A8%D8%B1%D8%B3%D8%A7%D8%AE%D8%AA-%D8%A7%D8%AC%D8%AA%D9%85%D8%A7%D8%B9%DB%8C-%D8%A7%D8%B2%D8%AF%D9%88%D8%A7%D8%AC-%D8%B3%D9%81%DB%8C%D8%AF}}</ref><ref>{{Cite journal |last1=Omidvar |first1=Pouran |last2=Danesh |first2=Parvaneh |last3=Javaheri |first3=Fatemeh |last4=Zahedi Mazandarani |first4=Mohammad javad |date=2019-03-10 |title=Studying the cohabitation subculture in metropolis Tehran (backgrounds and consequents) |journal=Social Welfare Quarterly |volume=18 |issue=71 |pages=279–320 |doi=10.29252/refahj.18.71.8 |s2cid=200062397|doi-access=free }}</ref><ref>{{Cite web |title=Beyond the Shari'a: "White Marriages" in the Islamic Republic of Iran |publisher=Association for Iranian Studies (AIS) {{!}} انجمن ایران‌ پژوهی |url=https://associationforiranianstudies.org/content/beyond-sharia-white-marriages-islamic-republic-iran|access-date=2023-02-04|website=associationforiranianstudies.org}}</ref><ref>{{Cite web |title="ازدواج سفید شبه قانونی" بدیلی در برابر ازدواج سنتی؟ – DW – ۱۳۹۶/۸/۱۱ |trans-title="White quasi-legal marriage" an alternative to traditional marriage? - DW - 8/11/1396 |website=dw.com |language=fa |url=https://www.dw.com/fa-ir/%D8%A7%D8%B2%D8%AF%D9%88%D8%A7%D8%AC-%D8%B3%D9%81%DB%8C%D8%AF-%D8%B4%D8%A8%D9%87-%D9%82%D8%A7%D9%86%D9%88%D9%86%DB%8C-%D8%A8%D8%AF%DB%8C%D9%84%DB%8C-%D8%AF%D8%B1-%D8%A8%D8%B1%D8%A7%D8%A8%D8%B1-%D8%A7%D8%B2%D8%AF%D9%88%D8%A7%D8%AC-%D8%B3%D9%86%D8%AA%DB%8C/a-41206307|access-date=2023-02-04}}</ref>

New research published by social anthropologist Kameel Ahmady and his team under the title '''''House with Open Door'':''' ''A Comprehensive Research Study on White Marriage (Cohabitation) in Iran'' reveals the previously concealed and multi-dimensional aspects of this phenomenon at the macro level, focusing on the [[Place:Tehran|Tehran]], [[Place:Mashhad|Mashhad]] and [[Place:Isfahan|Isfahan]] metropolitan areas.

While couples of all ages cohabit, the phenomenon is much more common among younger people. In late 2005, 21% of families in Finland consisted of cohabiting couples (all age groups).<ref>{{cite web |date=2006-06-01 |title=The Finnish population structure of 2005 |url=http://www.stat.fi/til/perh/2005/perh_2005_2006-06-01_tie_001.html |website=Statistics Finland |language=fi}}</ref> Of couples with children, 18% were cohabiting.{{citation need |date=June 2023}} Of ages 18 and above in 2003, 13.4% were cohabiting.<ref>{{cite web |url=http://www.stat.fi/til/evaa/2003/evaa_2003_2004-05-31_kat_002_en.html |title=Elected MPs and candidates by family type in 2003 |website=Statistics Finland |language=en}}</ref> Generally, cohabitation amongst Finns is most common for people under 30. Legal obstacles for cohabitation were removed in 1926 in a reform of the Criminal Code, while the phenomenon was socially accepted much later on.

The [[History:Victorian era|Victorian era]] of the late 19th century is famous for the Victorian standards of personal morality.  Historians generally agree that the middle classes held high personal moral standards and rejected cohabitation. They have debated whether the working classes followed suit. Moralists in the late 19th century such as Henry Mayhew decried high levels of cohabitation without marriage and illegitimate births in London slums. However new research using computerized matching of data files shows that the rates of cohabitation were quite low—under 5% – for the working class and the urban poor.<ref>{{cite magazine |author=Rebecca Probert |title=Living in Sin |magazine=BBC History Magazine |date=Sep 2012}}</ref><ref>{{cite book |last=G.

Falling marriage rates and increased births outside marriage have become a political issue, with questions of whether the government should promote marriage or focus on the status of a parent rather than a spouse; the [[Finance:Conservative Party (UK)|Conservative Party]] support the former whilst Labour Party and the Liberal Democrats support the latter.<ref>{{cite web|title=Marriage and cohabitation: key issues for the 2010 Parliament|work=UK Parliament |url=http://www.parliament.uk/business/publications/research/key-issues-for-the-new-parliament/social-reform/marriage-and-cohabitation/|access-date=22 August 2015}}</ref> There are also differences between England and Wales and Scotland, with the latter being more accepting of cohabitation.<ref>{{cite web|title=Family Matters – Cohabitation |publisher=Scottish Government |url=http://www.gov.scot/Topics/Justice/law/17867/fm-couples-root/fm-couples-cohabitation|access-date=22 August 2015 |url-status=dead|archive-url=https://web.archive.org/web/20150924040817/http://www.gov.scot/Topics/Justice/law/17867/fm-couples-root/fm-couples-cohabitation|archive-date=24 September 2015}}</ref><ref>{{cite web|website=Family Law Week|title=Lessons to be learned for cohabitation cases in England, says Lady Hale in Supreme Court Scottish case |url=http://www.familylawweek.co.uk/site.aspx?i=ed98906 |access-date=22 August 2015 |archive-date=10 March 2023 |url-status=dead |archive-url=https://web.archive.org/web/20230310081023/https://www.familylawweek.co.uk/site.aspx?i=ed98906}}</ref>

====Bulgaria====

In Bulgaria, there has been a rapid increase in cohabitation after the fall of Communism. The transition from communism to market economy had a great impact on the demographic behavior of the population. After the fall of Communism, the legal and social pressure to get married has declined, and the population has started to experience new life styles.<ref name="Elena von der Lippe"/> As of 2014, 58.8% of children were born to unmarried mothers.<ref>{{Cite web |title=Population and Demographic Processes in 2014 (Final Data) |publisher=Republic of Bulgaria: National Statistical Institute |url=https://nsi.bg/sites/default/files/files/pressreleases/Population2014_en_2Y19BGI.pdf|access-date=2022-08-07}}</ref>

====Czech Republic====

The marriage rates in Czech Republic have fallen dramatically during the past decades. In the 1970s to 1980s, about 96–97% of women married; in 2000 it was estimated that only 75% of women would ever marry.<ref name="paa2004.princeton.edu">{{Cite web |last=Kantorova |first=Vladimira |title=Marriage or cohabitation: First union formation in the Czech Republic |url=https://paa2004.princeton.edu/papers/41732 |access-date=7 August 2022 |website=princeton.edu |archive-date=7 August 2022 |archive-url=https://web.archive.org/web/20220807132131/https://paa2004.princeton.edu/papers/41732 |url-status=dead }}</ref> The age at first marriage for women has increased from being in the range of 21.4–21.8 years in the 1970s and 1980s,<ref name="paa2004.princeton.edu"/> to being 29.6 in 2011.<ref>{{cite web |title=FirstMariages by Age, Sex, Measurement, Country and Year |website=UNECE Statistical Database |publisher=United Nations Economic Commission for Europe |url=https://w3.unece.org/PXWeb2015/pxweb/en/STAT/STAT__30-GE__02-Families_households/051_en_GEFH_FirstMariages_r.px/table/tableViewLayout1/ |access-date=2023-06-26}}{{verification failed|date=June 2023|reason=Query returned "data not available".}}</ref> In the early 1990s, predictions were made by some Czech demographers that cohabitation would increase during the next decades; and indeed, there has been a marked increase in the number of people who live in non-marital couple relations.<ref>{{Cite journal |last=Hamplová |first=Dana |date=5 June 2002 |title=Marriage and Cohabitation: Qualitative Differences in Partnership Arrangements |journal=Sociologický časopis |trans-journal=Czech Sociological Review |volume=38 |issue=6 |pages=771–788 |url=http://sreview.soc.cas.cz/pdfs/csr/2002/06/05.pdf |access-date=7 August 2022}}</ref> In 2016, 48.6% of births were to unmarried women.<ref name=tps00018/>

====Germany====
Until the 1980s, it was illegal for unmarried couples to cohabitate, which made it impossible for many same-sex couples to live together. At this point the Bundesgerichtshof ruled that cohabitation could not be banned as it was protected by the Basic Law.<ref>{{cite web |title=Von 1933 bis heute: Lesben und Schwule in Deutschland und der DDR |url=https://www.lsvd.de/de/ct/934-von-1933-bis-heute-lesben-und-schwule-in-deutschland-und-der-ddr |website=www.lsvd.de |access-date=1 November 2021 |language=de}}</ref>
As in other western societies, patterns of family life have been changing in Germany during the past decades.

====Greece====
In Greece, family dynamics remain conservative. The principal form of partnership is marriage, and extramarital childbearing and long term cohabitation are not widespread. For instance, in 2016 only 9.4% of births were outside marriage, which is the lowest percentage among the European Union member states.<ref name=tps00018/> Religion in Greece plays a very important role in society; it was only in 1983 that [[Social:Civil marriage|civil marriage]] was introduced in the country. The new laws modernized [[Social:Family law|family law]], abolished [[Social:Dowry|dowry]], and provided for equal rights for "[[Social:Legitimacy (family law)|illegitimate]]" children.<ref>{{cite journal |last1=Marcos |first1=Anastasios C. |last2=Bahr |first2=Stephen J. |date=2001 |title=Hellenic (Greek) Gender Attitudes |journal=Gender Issues |volume=19 |issue=3 |pages=21–40|doi=10.1007/s12147-001-0009-6 |s2cid=143989412 }}</ref><ref>{{cite news |title=AROUND THE WORLD; Greece Approves Family Law Changes |agency=Reuters |url=https://www.nytimes.com/1983/01/26/world/around-the-world-greece-approves-family-law-changes.html# |newspaper=The New York Times|date=26 January 1983}}</ref><ref>{{cite conference |last=Demos |first=Vasilikie |date=11 August 2007 |title=The Intersection of Gender, Class and Nationality and the Agency of Kytherian Greek Women |conference=Aannual meeting of the American Sociological Association}}</ref> According to a 2008 study: "Greek society still remains conservative and birthing outside marriage, although protected by law, remains in many ways socially unacceptable."<ref>{{cite web |url=https://www.internationaljournalofcaringsciences.org/docs/vol1_issue3_04_sapountzi.pdf |title=Greek mothers' perceptions of their cooperation with the obstetrician and the midwife in the delivery room.}}</ref> Despite this, there have been further legal changes providing for a modern "western" outlook on family life, including Law 3719/2008 dealing with family issues, including Article 14 of the law, which reduced the separation period (necessary before a divorce in certain circumstances) from four years to two years.<ref>{{cite web |url=https://www2.ohchr.org/English/bodies/cedaw/docs/54/CEDAW-C-GRC-7.pdf |title=Consideration of reports submitted by States parties under article 18 of the Convention on the Elimination of All Forms of Discrimination against Women |publisher=Committee on the Elimination of Discrimination against Women}}</ref>

====Hungary====
The literature on second demographic transition argues as well that highly educated women are more prone to engage in cohabitation, although the reasons are different: they are less concerned with respecting the societal norms.<ref>{{cite journal |vauthors=Lesthaeghe R |year=1983 |title=A Century of Demographic and Cultural Change in Western Europe: an Exploration of Underlying Dimensions |journal=Population and Development Review |volume=9 |issue=3| pages=411–435 |doi=10.2307/1973316| jstor=1973316}}</ref> Some scholars argued that cohabitation is very similar to being single in the sense of not giving up independence and personal autonomy.<ref>{{cite journal |vauthors=Rindfuss RR, van del Heuve A |year=1990 |title=Cohabitation: A precursor to marriage or an alternative to being single? |journal=Population and Development Review |volume=16 |issue=4| pages=703–726 |doi=10.2307/1972963| jstor=1972963}}</ref>

In Hungary, cohabitation was an uncommon phenomenon until the late 1980s and it was largely confined to the divorced or widowed individuals.<ref>{{cite journal |vauthors=Carlson E, Klinger A |year=1987 |title=Partners in life: Unmarried couples in Hungary |journal=European Journal of Population |volume=3 |issue=1| pages=85–99 |doi=10.1007/bf01797093| pmid=12280732 |s2cid=3691282}}</ref> Among the ethnic groups, Gypsy/Roma tended to have higher rates of cohabitation, mainly due to their reluctance to register their marriages officially.<ref>{{cite book |last=Barany |first=Zoltan |year=2002 |title=The East European Gypsies.

Marginality, and Ethnopolitics |publisher=Cambridge University Press}}</ref> Since the 1980s, cohabitation became much more frequent among all ethnic groups and it has been argued to have strongly influenced the decline in fertility.<ref>{{cite report |last=Speder |first=Zsolt |date=July 2001 |title=Turning Points of the Life Course |place=Budapest |publisher=Demographic Research Institute |url=http://demografia.hu/hu/letoltes/adatbazisok/eletunk-fordulopontjai/kutatasi_koncepcioEN.pdf |access-date=2023-06-26 |url-status=live |archive-date=2023-06-26 |archive-url=https://web.archive.org/web/20230626041541/http://demografia.hu/hu/letoltes/adatbazisok/eletunk-fordulopontjai/kutatasi_koncepcioEN.pdf}}</ref> In 2015, 47.9% of births were to unmarried women.<ref name=tps00018/>

====Ireland====

[[File:Magdalen-asylum.jpg|upright=1.15|thumb|Irish Magdalene Laundry, {{circa|lk=no}} early 1900s. Women who had sexual relations outside marriage were often sent to Magdalene laundries until the mid-20th century]]

Cohabitation in Ireland has increased in recent years, and 36.6% of births were to unmarried women in 2016.<ref name=tps00018/> Until a few decades ago, women who had children outside marriage were severely stigmatized and often detained in Magdalene laundries. The Civil Partnership and Certain Rights and Obligations of Cohabitants Act 2010 gives some rights to unmarried cohabitants (under this act same-sex couples can enter into civil partnerships, while long term unmarried couples – both heterosexual and same sex – who have not registered their relation have some limited rights and obligations).

====Italy====

In Italy, where Roman Catholicism had a historically strong presence, cohabitation is not as common as in other countries of Europe, yet it has increased in recent years. There are significant regional differences, with non-marital unions being more common in the North of the country than in Southern Italy. A study published in 2006 found that long term cohabitation was still novel to Italy, though more common among young people.<ref>{{cite journal|title=Cohabitation in Italy: do parents matter?|journal = Genus|volume = 62|issue = 3/4|pages = 53–85|jstor = 29789325|last1 = Schröder|first1 = Christin|year = 2006}}</ref> As of 2015, the share of births outside marriage was 28.7%, but this varied by statistical regions as follows: Central Italy (33.8%), Northeast Italy (33.1%), Northwest Italy (31.3%), Insular Italy (24.2%), and South Italy (20.3%).<ref>{{Cite web |date=28 November 2016 |title=NATALITÀ E FECONDITÀ DELLA POPOLAZIONE RESIDENTE |url=https://www.istat.it/it/files/2016/11/Statistica-report-Nati.pdf?title=Natalit%C3%A0+e+fecondit%C3%A0++-+28%2Fnov%2F2016+-+Testo+integrale+e+nota+metodologica.pdf |access-date=7 August 2022}}</ref>

====The Netherlands====

Dutch researchers have found that research participants see cohabitation as a risk-reduction strategy in a country with high relationship instability.<ref>{{cite journal |title=Risk-avoidance or utmost commitment? Dutch focus group research on cohabitation and marriage |author=Nicole Hiekel |author2=Renske Keizer |journal=Demographic Research |volume=32 |pages=311–340 |date=3 February 2015 |doi=10.4054/DemRes.2015.32.10 |doi-access=free |url=http://www.demographic-research.org/volumes/vol32/10/32-10.pdf}}</ref> As of 2016, 50.4% births were to unmarried women.<ref name=tps00018/>

====Norway====

Cohabitation is a common type of partnership in Norway. Cohabitants have some rights if they have joint children, or if they have lived together for five years. Cohabitants can also regulate their relationship through a [[Finance:Cohabitation agreement|cohabitation agreement]].<ref>{{cite web|url=http://www.nyinorge.no/en/Familiegjenforening/New-in-Norway/Families-and-children-in-Norway-/Families-and-children-in-Norway/Cohabitation/|title=Cohabitation|access-date=22 August 2015|archive-url=https://web.archive.org/web/20150722130026/http://www.nyinorge.no/en/Familiegjenforening/New-in-Norway/Families-and-children-in-Norway-/Families-and-children-in-Norway/Cohabitation/|archive-date=22 July 2015|url-status=dead}}</ref> In Norway, in 2016, 56.2% of children were born outside marriage.<ref name=tps00018/>

====Poland====
In Poland, after the fall of Communism, the influence of religion has increased. Indeed, Poland has one of the most religious populations in Europe (see religion in Europe). Cohabitation in Poland has traditionally been associated with the lower social classes, but in recent years an increase has been seen among the more educated. Family structure in Poland remains traditional: Marriages are contracted at relatively young ages, and the incidence of divorce is relatively low (by European standards). The exact incidence of cohabitation is not well established, but it is quite low compared to other Western countries. However, Poland is not completely 'immune' to Western influence and, in 2016, 25% of children were born outside marriage.<ref name=tps00018/><ref>{{Cite web |last=Matysiak |first=Anna |date=18 August 2009 |title=Is Poland really 'immune' to the spread of cohabitation? |url=http://www.demographic-research.org/volumes/vol21/8/21-8.pdf |access-date=7 August 2022 |website=Demographic Research}}</ref>

====Slovakia====
Slovakia is more conservative and religious than neighboring Czech Republic. The principal form of partnership is marriage, but extramarital childbearing and cohabitation are slowly spreading, yet this trend is not without criticism; and some view these phenomena as a threat to traditional values.<ref name="demographic-research.org">{{cite journal |url=https://www.demographic-research.org/volumes/vol19/25/19-25.pdf |title=Slovakia: Fertility between tradition and modernity |year=2008 |publisher=Max Planck Institute for Demographic Research |doi=10.4054/DemRes.2008.19.25 |last1=Potancokova |first1=Michaela |last2=Vano |first2=Boris |last3=Pilinská |first3=Viera |last4=Jurcová |first4=Danuša |journal=Demographic Research |volume=19 |pages=973–1018}}</ref><ref>{{cite web |author=Michaela Potančoková |publisher=Demographic Research Centre |place=Bratislava, Slovakia |title=The Meaning of Cohabitation and Marriage in Slovakia: Comparing Generation |url=http://www.oeaw.ac.at/vid/download/col100319mp.pdf |access-date=17 July 2014 |url-status=dead |archive-url=https://web.archive.org/web/20140726132730/http://www.oeaw.ac.at/vid/download/col100319mp.pdf |archive-date=26 July 2014}}</ref> In 2016, 40.2% of births were to unmarried women.<ref name=tps00018/> Fertility in Slovakia has been described in a 2008 study as "between tradition and modernity".<ref name="demographic-research.org"/>

====Switzerland====
{{wipe|Switzerland}} has a tradition of strong conservatism; which can be seen in its legal and social history: in Europe, Switzerland was one of the last countries to establish gender equality in marriage: married women's rights were severely restricted until 1988, when legal reforms providing gender equality in marriage, abolishing the legal authority of the husband, come into force (these reforms had been approved in 1985 by voters in a referendum, who narrowly voted in favor with 54.7% of voters approving).<ref>{{cite news |url=https://www.nytimes.com/1985/09/23/world/swiss-grant-women-equal-marriage-rights.html |title=Swiss Grant Women Equal Marriage Rights |newspaper=The New York Times|date=23 September 1985}}</ref><ref>{{cite news |url=https://www.bbc.com/news/world-europe-17988450|title=Switzerland profile – Timeline|work=BBC News|date=28 December 2016}}</ref><ref>{{cite web|url=http://history-switzerland.geschichte-schweiz.ch/chronology-womens-right-vote-switzerland.html|title=The Long Way to Women's Right to Vote in Switzerland: a Chronology|first=Markus G.

====Russia====

In Russia, many couples express a desire to cohabit before marriage, then register a civil marriage, and then at a later stage have a large church wedding.<ref>{{cite journal |title=Trust, responsibility, and freedom: Focus-group research on contemporary patterns of union formation in Russia |author=Olga Isupova |journal=Demographic Research |volume=32 |pages=341–368 |doi=10.4054/DemRes.2015.32.11 |date=3 February 2015 |doi-access=free |url=http://www.demographic-research.org/volumes/vol32/11/32-11.pdf}}</ref>

The cohabitation rate in West Asian countries is much lower than in European countries. In some parts of the continent it is however becoming more common for young people.

==== Kuwait ====
Some legal recognition is extended to former common-law unions in Kuwait. Kuwaiti Family law applies the law of the father's, husband's or male partner's country in case of expatriate familial disputes. Hence, if the father's country of nationality recognises common-law marriages (like the United Kingdom), matters such as [[Social:Child support|child support]] dues and [[Social:Alimony|maintenance]] can be considered in a Kuwaiti court.<ref name=":0">{{Cite web |title=Expat divorce in Kuwait |website=Expatriate Law |url=https://expatriatelaw.com/where-to-divorce/divorce-where-you-live/expat-divorce-in-kuwait/|access-date=11 October 2020}}</ref> However, out-of-marriage sexual intercourse is an offence punishable in Kuwait with a prison sentence between 6 months and 6 years if caught in action by an official or an administrative deportation order.
