Long-Term Trends in Occupational Segregation by Sex

This paper reexamines long-term trends in occupational segregation by sex, using the double-coded 1900 and 1910 Public Use Samples. The analysis addresses the ambiguity in the measurement of longterm trends that arises from using inconsistent or highly aggregated occupational classifications. The revised measures indicate that occupational segregation by sex remained quite constant from 1900 through 1970, although segregation in nonfarm occupations declined slowly. Occupational sex segregation declined between 1970 and 1980 and continued to decline through 1986. An accurate assessment of historical trends is a necessary starting point for theoretical explanations of occupational sex segregation.
