The study examines the increasing levels of female labor in the economy over the period between 1940 and 1970. Married women with husbands present show the most pronounced increase in participation rates with increases in every age group. Chart 1 and Table 1 present data on the percentage of women in the U. S. labor force over this period by both age and marital status. Table 2 provides statistics on the contribution that working wives make to family incomes. In dealing with the question of female status and mobility for the Unites States' (1940-1970) and New York State (1960-70), occupational areas were defined and examined: professionals, managers, clerical workers, craftsmen, operatives, service workers, and laborers. Tables 3 and 4 and Appendix A illustrate the results. New York showed a stable rate in female employment in clerical occupations, a decrease in manufacturing and laborer occupations, with an increase in medicine and other professions, contrasting with some of the national norms and reflecting a combination of factors. Twelve measures of female/male occupational mobility; indexes of the seven occupational groupings for both New York and the U. S. in graphic form, and a summary of the methodology are appended. (JB)
