The report noted that "most people consider families and households as their most important social institutions and social reference groups," relying on them for "physical, social and economic wellbeing and survival".
"Although traditional family structures are changing, they remain very important in countries such as SA, where large proportions of the population are subject to debilitating poverty and unemployment and institutional support is inadequate."
The survey found that for people aged 18 to 34, living together and marriage was more common among young women than men.
This trend was reversed in older age groups, however: "Marriage and cohabitation were much more common amongst males (75%) than females (40%) in the age group 60-74 ... By contrast, 80.6% of women in the age group 75 years and older remained single or widowed, compared to 24.4% of males in this age group."
