National Natality Followback Survey, 1964-1966 (ICPSR 21961)
Principal Investigator(s): United States Department of Health and Human Services. Centers for Disease Control and Prevention. National Center for Health Statistics
This collection provides information on a sample of live births in the United States during the calendar years 1964-1966. The natality data in this file are a component of the vital statistics collection effort maintained by the federal government. Geographic variables of residence for births include the state and county, and metropolitan/nonmetropolitan county. Other variables include health insurance coverage, the place of delivery, whether there was an attendant at birth, legitimacy of the child, live-birth order, and the type of delivery. Demographic variables include each sample child's sex and race, birth weight, date of birth, date of death, the parents' age and race, date of birth, education level, place of birth, family income, as well as the mother's marital history, household composition, and employment status during pregnancy. Information was also collected on the sex, date of birth, and date of death of the mother's previous births.

Universe: Live births in the United States during the calendar years 1964-1966.

Data Collection Notes:
ICPSR created a unique sequential record identifier variable named CASEID for use with online analysis.
More information on Natality studies may be found via the National Center for Health Statistics Web Site.
The codes for variables CO_OCCUR, COUNTY, ST_FILE_NO, DAD_STFC_CODE, and MOM_STFC_CODE were not included with the data.
Value labels for unknown codes were added in the variable CODE_00.
Users of this study may also be interested in ICPSR study NATALITY FOLLOWBACK SURVEY, 1972 (ICPSR 8112), as well as the rest of the studies in the Natality Detail File Series.
The variable CHILD2_BIRTHDAY was converted from character to numeric.
Variables MOM_BIRTHDAY, DAD_BIRTHDAY, M1MARRY_DAY, MPMARRY_DAY, TERM_DAY, BIRTHDAY_SCHILD, CHILD1_BIRTHDAY through CHILD17_BIRTHDAY, and CHILD1_DEATHDAY through CHILD11_DEATHDAY were blanked for confidentiality.
Weight: (1) The variable ANNUAL_WGT (Annual Weight Factor) in this dataset refers to a proportion, but the values are whole numbers. According to the original documentation, each record was assigned a weight factor based on the mother's age, color [race], and live birth order from the U card data. (2) The variable WEIGHT (Three Year Average Weight) in this dataset refers to a proportion, but the values are whole numbers. According to the original documentation, each record was assigned a three year average weight factor based on the mother's age, color [race], and live birth order from the U card data. This weight should be used when tables for the three years combined data are run.
