In the past, arranged marriages were common. However, this practice is becoming more rare, and a law was passed that gave authority to a state-appointed judge to overrule the wishes of the father in the event of an early marriage. The Muslim majority traditionally views marriage as a contract between two families, as the family's needs are considered most important. In urban settings, women and men have more options in choosing their spouses, though the proposed spouse still must have parental approval. Partners often come from the same kin group, and though marriage between different ethnic groups is accepted, it is not too common. The ruling Baath regime considers marriage to be a national duty that should be guided and encouraged. Starting in 1982, women were forbidden to marry non-Iraqi men. If they were already married, they were prohibited from transferring money or property to their spouses.

Following the Iran-Iraq War, the loss of men's lives was so severe that the government embarked on a campaign to increase the population. Government grants were given to men to marry war widows, and polygamy, once rare, became more common. Divorce is accepted, but usually is left solely as a decision of the husband. If the husband wishes to be divorced, it is normally without question or problem, while it is close to impossible for a woman to initiate a divorce proceeding. In the event of divorce, custody is supposed to be granted based on what is best for the child's welfare.

Couples can live in either of two ways: with the husband's extended family, or as a nuclear family. At present, with economic hard-ships, families tend to live with extended households. The extended family unit consists of the older couple, sons, their wives and families, and unmarried daughters. Other dependent relatives also may make up part of this group, and the oldest male heads the group. He manages property and makes the final decisions regarding such things as the type of education the children receive, their occupations, and whom they will marry. In this living arrangement household and child-rearing tasks are shared among all female members of the larger families. If the couple can afford to live in a nuclear household, women, even though they work outside the home, retain all domestic and child-care responsibilities. The challenge of the woman's role in this situation is that there is no change in cooking methods or materials, and they are isolated from the help and emotional support of other female family members. Families often grow large, because the Iraqi government has stated that every family should have five children, as four children or fewer is considered a threat to national security. Considering the extreme hardships families now face in light of economic hardship and harsh living conditions, the goal of many is now to simply feed their families and preserve a semblance of some sort of home life.

Children are the mother's responsibility, and in extended domestic units other female members also take care of the children. Children normally imitate older siblings, and obedience and loyalty to elders are of vital importance. Boys and girls have different upbringings, as a boy's birth into the family is usually celebrated, while a girl's typically is not. The boy is thought to be more valuable to a family, given his potential to work, while the girl is considered more of a dependent. At puberty girls are separated from boys and have much less freedom than boys.

In general, both adults and children keep to themselves and are not loud and boisterous, especially in public. Men commonly hold hands or kiss when greeting each other, but this is not the case for men and women. Respect is given to the elderly and women, especially those with children, as men give up their seats to them on buses and trains.
