U.S. National Fertility Study, 1975

  • 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. 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 Infant Mortality Survey, 1964-1966

  • 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

  • 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 Study of High School and Beyond, Selected Variables: A Longitudinal Study of Female Sophomores, 1980-1982

  • U.S. National Study of High School and Beyond, Selected Variables: A Longitudinal Study of Female Sophomores, 1980-1982

    Investigators: Peter Morrison, Linda Waite, and Allan Abrahamse

    This is the second of two National Longitudinal Studies (NLS). The first, NLS-72, began with over 22,000 high school seniors in the spring of 1972. The second study began with a 1980 collection of base year data on individual and family background, high school experiences, work experiences, plans for the future, and cognitive ability and achievement from high school seniors and sophomores. The first follow-up was conducted in the spring of 1982, and a second follow-up was conducted in 1984. The current Data Set was designed to build on the NLS-72 by replicating selected 1972 study questionnaire and cognitive test items as well as expanding the data to include a broader range of lifecycle factors, such as family-formation behavior and social participation. Over 30,000 sophomores enrolled in 1,015 public and private high schools across the country participated in the Base Year survey, with questionnaires administered at schools or appropriate off-campus locations. The 1982 follow-up sample consisted of approximately 30,000 1980 sophomores, with different questionnaires for those who had dropped out of school and those who remained enrolled in school. The DAAPPP file is an extract designed by Peter Morrison and his colleagues at the Rand Corporation. The cases were limited to female high school sophomores who were not mothers at the time of the 1980 baseline survey. In addition to the approximately 100 variables obtained directly from the High School and Beyond Data Set, the investigators computed approximately twenty scale score and indicator variables.
