!Kung men have received scant attention in the preceeding chapters, since we focused—as most demographic studies do—on fertility process as a function of the women. This chapter will attempt to repair the neglect, showing parallel data for men for some of the issues raised for the women, issues such as the timing of growth and maturation, entrance into marriage, and fertility. Some of the data in this chapter comes from direct observation of the !Kung men during 1967–1969, some comes from the women’s reports on their husbands, and some has been provided by R. B. Lee, who carried out an interviewing study of the men at the time I was studying the women.
