U.S. National Fertility Study, 1970

Investigators: Norman Ryder and Charles Westoff

This study is the second wave of a three-part fertility study which began with the 1965 National Fertility Study (NFS) (documented as DAAPPP Data Set No. 48-49), and ended with the 1975 NFS (documented as DAAPPP Data Set No. 52). A national probability sample of ever-married women under 45 years of age was interviewed for this study. The data cover contraceptive efficacy, fecundability, attitudes toward abortion, sex roles, and world population issues. Also available are detailed background data on respondents and their spouses (age, education, religion and religiosity, ethnicity, occupation, family income, financial conditions). The microcomputer version of the raw data is an extract of 1,125 cases. Note for users of DAAPPP Data Sets #01-B1DAAPPP data sets 01 through B1 are comprised of a User's Guide, SPSS syntax files (*.SPS or *.SPX) and raw data files only. Most of these datasets contain SPSS syntax files that use Job Control Language (JCL) from 1980s versions of SPSS-X. Because the syntax is old, the syntax files require editing to conform to the current syntax standards used by SPSS/Windows or SPSS/Unix.

U.S. National Fertility Study, 1975

Investigators: Charles Westoff and Norman Ryder

This is the third in a series of studies begun in 1965 and continued in 1970 (documented as DAAPPP Data Set Nos. 48-49 and 50-51, respectively). Unlike its predecessors, this study was longitudinal in its design. The data collected were from a national probability sample of once-married and currently married women who were white, married fewer than 25 years and before the age of 25, and whose husbands were also once-married. Reinterview data were also collected from continuously married respondents to the 1970 survey (an interval of approximately five years). The sample included 1,042 new respondents, together with 2,361 women reinterviewed, for a total of 3,403 respondents. In addition to the scope of previous studies, the present data includes new information on those reinterviewed, such as success in fertility forecasting. This dataset is an extract of 1,134 cases.

U.S. National Fetal Mortality Study, 1980

Investigators: National Center for Health Statistics

This nationally representative study is based on a sample of 6,386 vital records for fetal deaths occurring at 28 weeks gestation or more in the United States in 1980. As with DAAPPP Data Set No. 82-83, married mothers, hospitals, attendants at delivery, and other medical providers of radiation procedures (four groups that were associated with the sampled deliveries) were mailed 8-page questionnaires. Information on demographic and social characteristics, maternal health, infant health, labor and delivery practices and radiation exposure before and during pregnancy was assessed. The survey was limited to late fetal deaths which were more likely to have occurred in a hospital. Abortions were also excluded from this study. The final sample represents 1 in 3 of the estimated number of late fetal deaths in 1980. The microcomputer version of the raw data is an extract of 1,064 cases.

U.S. National Infant Mortality Survey, 1964-1966

Investigators: National Center for Health Statistics

The study is a collection of data for a sample of infant deaths occurring in calendar years 1964, 1965, and 1966. Each data record is composed of information obtained from the death certificate and from a questionnaire that was sent to the mother of the deceased child. The survey extends, for statistical purposes, the range of items normally included in the vital records, providing national estimates of infant deaths by characteristics not available from the vital registration system and serving as a basis for evaluating the quality of information reported on the vital records. Data include information on hospitalization of the infant who died, other children of the mother, household composition, income, employment of mother, education of parents and health insurance. The nationally representative survey was based on a sample of infant death vital records (1 out of 110 infant deaths) with a response rate of 88 per cent. The sample size is 7,866 cases; weights applied to the 2,490 cases of infant deaths in 1964-1966 may be used to reflect U.S. estimates of infant deaths during the study period.

U.S. National Natality Survey, 1964-1966

Investigators: National Center for Health Statistics

The study is a collection of data for a sample of live births to married women occurring in calendar years 1964, 1965, and 1966. The survey extends, for statistical purposes, the range of items normally included on the vital records. It provides national estimates of births by characteristics not available from the vital registration system. It also serves as a basis for evaluating the quality of information reported on the vital records. Each data record is composed of information obtained from the birth certificate, and from questionnaires sent to the mother, the physician who delivered the baby, and the medical facility where the baby was born. The survey gathered information on pregnancy history, expectations of having more children, household composition, income, whether this was a first or later marriage, date of first marriage and date of this marriage, whether mother was employed and when during her pregnancy she stopped working, education, and health insurance. One out of 1,000 births were originally selected. This data file contains only the subsample of married mothers. Data were collected primarily by mail from addresses given on the birth certificates. The response rate was 89 percent. The total sample size is 10,395 cases. Weights may be used to reflect U.S. estimates of infant births during the study period.

U.S. National Natality Survey, 1967

Investigators: National Center for Health Statistics

The National Natality Surveys were conducted over a number of years between 1964 and 1980. The 1967 survey was designed primarily to collect information on pre- and post-natal care received by women and by their newborn infants. Additional information was obtained on certain socioeconomic and demographic characteristics. The initial source of data were certificates of live births. Every 1,000th legitimate white infant and every 500th legitimate non-white infant were sampled and questionnaires mailed to 3,511 mothers. The final response rate was 91%. Values for most missing data were imputed for those who did not respond as well as for an additional 65 births who were selected but not mailed questionnaires.

U.S. National Natality Survey, 1972

Investigators: National Center for Health Statistics

The survey is nationally representative based on a sample of 5,689 vital records of live birth in the United States in 1972, conducted by the National Center for Health Statistics. Married mothers, hospitals, and physicians were mailed different questionnaires. Their responses include information on demographic and social characteristics, maternal health, infant health, and labor and delivery history.Note for users of DAAPPP Data Sets #01-B1DAAPPP data sets 01 through B1 are comprised of a User's Guide, SPSS syntax files (*.SPS or *.SPX) and raw data files only.

U.S. National Natality Survey, 1980

Investigators: National Center for Health Statistics

This survey is a nationally representative sample of 9,941 vital records of live birth in the United States in 1980. Married mothers, hospitals, attendants at delivery, and other medical providers of radiation procedures (four groups that were associated with the sampled deliveries) were mailed 8-page questionnaires. Their responses include information on demographic and social characteristics, maternal health, infant health, labor and delivery practices and radiation exposure before and during pregnancy. The mothers received 15-minute telephone interviews, and the medical sources 5-minute reminders if they did not respond to two waves of mailed questionnaires.
