Humans, just like other mammals, tend to allow greater sexual freedom for men rather than women. Furthermore, females are burdened with the majority of parenting. Do parenting costs limit sexual unrestrictedness to a different degree for males and females? The authors find that across 48 cultures, as women’s parenting costs decreased through improved physiological and economic conditions, women’s sexual unrestrictedness increased.

This article examines the relationship between HIV/AIDS and several parameters of a nation’s demography, including income, mortality, labor, fertility, and homicide rates. Associations were supported by statistical tests. Regional differences are considered; Europe and the Muslim area had lower level of women’s HIV/AIDS infection. Four cultural adaptations to combat STDs are discussed.

This article investigates possible correlates of women’s overt political power in a cross-cultural sample. Rule of descent—specifically, matrilineal or double descent— is the only factor the author found to be associated with women’s overt political power. Several other factors, including sex ratio, subsistence type, contribution to subsistence, and political system, are not associated. The author also includes a discussion of political activity among chimpanzees, as well as a brief ethnographic summary of several societies in which women have political power.
