This volume is the third in a series based on a national sample of women who were 30-44 years of age when they first interviewed in mid-1967. The data for this third report were derived from personal interviews conducted in the summer of 1971. The report focuses on two problems which women in the labor force are likely to encounter, the first being the changing occupational distribution of women. The authors examined, for the time span 1967 to 1971, the extent to which women left (or entered) occupations which society viewed as "acceptable" for them, as well as the relationship between type of occupation and selected socioeconomic variables. The second problem examined is the changing demand for child care facilities. The report reviews changes which occurred between 1965 and 1971 in the utilization of different types of child care arrangements. (Author/PC)
