Cohabitation is when people live together in an emotionally- and/or physically-intimate relationship. The term is most frequently applied to couples who are not married.
People may live together for any of a number of reasons. These may include wanting to test compatibility or to establish financial security before marrying. It may also be because they are unable to legally marry, because for example same-sex, interracial or interreligious marriages are not legal or permitted. Other reasons include living with someone before marriage as a way to avoid divorce, a way for polygamists or polyamorists to avoid breaking the law, a way to avoid the higher income taxes paid by some two-income married couples (in the United States), negative effects on pension payments (among older people), philosophical opposition to the institution of marriage and seeing little difference between the commitment to live together and the commitment to marriage. Some individuals may also choose cohabitation because they see their relationships as being private and personal matters, and not to be controlled by political, religious or patriarchal institutions.
Some couples prefer cohabitation because it does not legally commit them for an extended period, and because it is easier to establish and dissolve without the legal costs often associated with a divorce. In some jurisdictions cohabitation can be viewed legally as common-law marriages, either after the duration of a specified period, or the birth of the couple's child, or if the couple consider and behave accordingly as husband and wife. (This helps provide the surviving partner a legal basis for inheriting the deceased's belongings in the event of the death of their cohabiting partner.)
Today, cohabitation is a common pattern among people in the Western world, especially those who desire marriage but whose financial situation temporarily precludes it, or who wish to prepare for what married life will be like before actually getting married, or because they see no benefit or value offered by marriage. More and more couples choose to have long-term relationships without marriage, and cohabit as a permanent arrangement.
In the Western world, a man and a woman who lived together without being married were once socially shunned and persecuted and potentially prosecuted by law. In some jurisdictions, cohabitation was illegal until relatively recently. Other jurisdictions have created a Common-law marriage status when two people of the opposite sex live together for a prescribed period of time. Most jurisdictions no longer persecute this private choice.
Opposition to cohabitation comes mainly from religious groups. Opponents of cohabitation usually argue that living together in this fashion is less stable and hence harmful. According to one argument, the total and unconditional commitment of marriage strengthens a couple's bond and makes the partners feel more secure, more relaxed, and happier than those that have chosen to cohabitation. Opponents of cohabitation commonly cite statistics that indicate that couples who have lived together before marriage are more likely to divorce, and that unhappiness, ill health, poverty, and domestic violence are more common in unmarried couples than in married ones. Cohabitation advocates, in turn, cite limited research that either disproves these claims or indicates that the statistical differences are due to other factors than the fact of cohabitation itself.
