Linked Birth/Infant Death Data, 1987 Birth Cohort: [United States] (ICPSR 6167)

Principal Investigator(s): United States Department of Health and Human Services. National Center for Health Statistics


This data collection consists of two data files, which can be used to determine infant mortality rates. The first file provides linked records of live births and deaths of children born in the United States in 1987 (residents and nonresidents). This file is referred to as the "numerator" file. The second file consists of live births in the United States in 1987 and is referred to as the "denominator" file. Variables include year of birth, state and county of birth, characteristics of the infant (age, sex, race, birth weight, gestation), characteristics of the mother (origin, race, age, education, marital status, state of birth), characteristics of the father (origin, race, age, education), pregnancy items (prenatal care, live births), and medical data.

Series: Linked Birth/Infant Death Data Series

Data Collection Notes:

Per agreement with NCHS, ICPSR distributes the data file(s) and technical documentation in this collection in their original form as prepared by NCHS. In 1988, the NHDS was redesigned to provide geographic sampling comparability with other surveys conducted by the National Center for Health Statistics (NCHS), to update the sample of hospitals selected into the survey, and to maximize the use of data collected through automated systems. Changes in the survey may affect trend data. That is, some of the differences between NHDS statistics based on the 1965-1987 sample and statistics based on the sample drawn for the new design may be due to sampling error rather than changes in hospital utilization.


Data Source:

birth and death certificates

Restrictions: In preparing the data tape(s) for this collection, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution, NCHS requires, under Section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that data collected by NCHS not be used for any purpose other than statistical analysis and reporting. NCHS further requires that analysts not use the data to learn the identity of any persons or establishments and that the director of NCHS be notified if any identities are inadvertently discovered. ICPSR member institutions and other users ordering data from ICPSR are expected to adhere to these restrictions.
