Noting that data from 1970 working life tables indicate that since 1960 worklife expectancy has continued to edge downward for men and to lengthen for women, this report briefly discusses continuing trends in the worklife of men and women from 1900 through 1970. Women's worklife is presented in terms of single women; mothers; widowed, divorced, separated women; childless women; and separations and accessions among women. The appendix comprises the majority of the report (13 pages) and includes a brief description of two measures of working life expectancy; and a six-page discussion of the working life table (its uses and a description which includes how data are computed for the number of persons living; percent of population in the labor force; number in the labor force; average number of remaining years of life, of working life for the population, of working life for the labor force, of nonlabor force activity for those in the labor force, and of nonlabor force activity for those in the population). The five 1970 working life tables are presented for men, single women, ever-married women to whom no children were ever born, ever-married women in the labor force after the birth of last child, and for divorced, widowed, and separated women.
