Much has been said about kinship and family in Latin America. The "Peruvian family" is of course not a homogeneous entity, but rather reflects both ethnic and socioeconomic factors. If there is a generalization to be made, it is that families in Peru, no matter what their status, show a high degree of unity, purpose, and integration through generations, as well as in the nuclear unit. The average size for families for the nation as a whole is 5.1 persons per household, with the urban areas registering slightly more than this and, contrary to what might be expected, rural families, particularly in the highlands, being smaller, with a national average size of 4.9 persons. This apparent anomaly runs counter to the expected image of the rural family. This is because the highland families that constitute the bulk of rural households have been deeply affected by the heavy migration of their members to the cities, coastal farms, and Selva colonizations.

Women's roles in the squatter settlements cover a wide mixture of tasks, including hauling water from corner spigots and beginning the daily preparation of food over kerosene stoves. In the 1975-91 time, the food supply for substantial numbers of the urban lower class in Lima and other coastal cities came from the United States Food for Peace (Public Law 480) programs administered by private voluntary organizations. Women also keep their wide-ranging family members connected, seeking the food supply with meager funds, and doing various short-term jobs for cash. According to social scientist Carol Graham, the poor urban areas have a high %age of female-headed households, as well as a large number of abandoned mothers who are left with the full responsibility for supporting their households and raising the children.
