Matrilocal residence is simply living with your mother's family after marriage. Think of it like staying with your mommy's house after you marry someone. It is a type of family living arrangement in which a married couple lives with or near the wife's family, rather than the husband's family. So, when a man gets married, he goes to live with his wife's family instead of his own. This is different from other types of residence patterns, like patrilocal residence, where the husband's family is where the couple goes to live.
Matrilocal residence is common in some cultures and societies, such as in many parts of Southeast Asia, Native American communities, and in some of the Pacific Islands. It can be seen as a way of continuing the mother's lineage and honoring her family.
In summary, matrilocal residence means living with your wife's family after marriage, and it is a way of family living that is practiced in some cultures and societies around the world.
