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. 13) contains data for 37,970 children aged 13 and under residing in households surveyed in the June 1980 CPS. This file is intended as a supplement to the files for women and men included in the June 1980 CPS (DAAPPP Data Set Nos. 11 and 12, respectively). It provides information on the age, sex, race, ethnic background, and relationship to household head for all children in the participating households.
