Indianapolis Fertility Study: Study of Social and Psychological Factors Affecting Fertility, 1941 (M086V1)

From the original codebook: Unlike other fertility studies which record fertility in terms of birth or pregnancy intervals, the Indianapolis study equated pregnancies and adoptions for the purposes of recording. This the fertility and contraception data contained on the tape are recorded in relation to "fertility events" and the periods between these events. The couples interviewed in the Indianapolis Study were classified as either "fecund" or "sterile." These terms are defined in the Glossary on p. 705 of the documentation. "Sterile" couples were given a different set of questionnaires than those for "fecund" couples. Virtually all of the Indianapolis Study analysis was restricted to the "fecund" couples. Only the data for the "fecund" couples have been incorporated into this tape. (Refers to original tape format.) The (original) tape consists of 4,275 variables. An additional 16 variables had to be deleted because the original data could not be reproduced in a meaningful way. The record length and blocksize are 4,667, and the number of cases is 1,444. The Indianapolis Study is based on weighted data. Weighting was accomplished by duplicating the cards of selected individual cases. Accordingly, the 1,444 cases contained on the tape include a number of duplicates. A list of cases that were duplicated appears in the Appendix to the documentation.</p
