The Current Population Survey (CPS) is a monthly household sample survey of individuals living in the 50 states and the District of Columbia. Conducted by the Bureau of the Census, this survey is intended to provide a basis for estimates of employment, unemployment, and other characteristics of the general labor force, of the U.S. population as a whole, and of various subgroups of the population. In this survey data on demographic characteristics and employment experiences, for the week preceding the survey, are obtained for household members aged 14 or over. Data are obtained through interviews with a single responsible member of the household.

Beginning in 1971, at the request of the National Institute of Child Health and Human Development, a special supplementary survey was conducted in selected years, in conjunction with the June CPS, to obtain data on individuals' marital and fertility histories and on their birth expectations. Data were also obtained on children residing in the household. The file described here (DAAPPP Data Set No. 12) contains data from the June 1980 CPS and fertility supplement. Specifically, it contains data for 63,845 men aged 14 and older that were included in that survey. This file is intended as a supplement to the file for women included in the June 1980 CPS (DAAPPP Data Set No. 11). It provides additional information on the spouse's education, and employment, and marital history, as well as information on other men in the household at the time of the survey.
