Household headship among unmarried persons in the United States, 1970-1985.

Recent trends in rates of household headship and headship differentials by sex and color are examined within the context of a model that expresses the likelihood of heading an independent household as a function of age, marital status, parental status, and individual money income. The parameters of this model are consistent with predictions derived from a "life-course" perspective and are stable across period, sex, and color. Nonetheless, residual effects of period, sex, and color persist even after the independent variables are taken into account.
