This databook presents 100 tables of statistics on the characteristics of working women in the United States and their changing socioeconomic status, especially during the 1970s. Most of these statistics are from the Current Population Survey (a household sample survey conducted monthly for the Bureau of Labor Statistics by the Bureau of the Census). Part 1 contains fifteen tables on the labor force participation of women between 1950 and 1979, with emphasis on trends during the 1970s. Five tables on the extent of work experience of men and women are provided in part 2. Part 3 consists of sixteen tables, which detail working women's marital, family, and child status. Changes in women's school enrollment and education are the subject of eleven tables in the fourth part. The seventeen tables provided in part 5 examine the earnings and income of women and families. Part 6 contains nineteen tables of data by race and Hispanic origin, and part 7 presents fourteen tables of additional information, including data on such subjects as job tenure and moonlighting. Part 8 concludes with three tables on labor force and employment patterns at the outset of the 1980s. (MN)
