Wife's Employment and Cumulative Family Size in The United States, 1970 and 1960
Using a multiple classification analysis of the data from the 1 percent public-use samples of the 1960 and 1970 censuses of population, it is found that the negative relationship between wives' employment and their cumulative family size is stronger among whites than nonwhites and is strongest among women married less than 10 years, with 12 or more years of schooling, and who have no relatives living with them. Moreover, although there are many similarities in the pattern of the employment status/fertility relationship between the 1960 and 1970 data, the relationship is weaker in 1970 than in 1960
