Data on Health and Well-being of American Indians, Alaska Natives, and Other Native Americans. National Vital Statistics System: Natality (NVSS-N)

12/01/2006

Sponsor: U.S. Department of Health and Human Services (DHHS)/Centers for Disease Control and Prevention (CDC)/National Center for Health Statistics (NCHS)
Description: The National Vital Statistics System Natality (NVSS-N) public-use data file comprises records of all documented births occurring within the United States. Data from all birth certificates filed in each state are included in this file. Specifically, these data cover the following information: residence of mother (e.g., population size of residence community, standard metropolitan statistical area, metropolitan and nonmetropolitan counties); demographic information about parents (e.g., race of parents, age of parents, education of mother and father, pregnancy/childbearing history of mother, marital status of mother); information on the infant (e.g., race, sex, Apgar scores at 5 minutes after birth, total-birth order); and information on the birth [e.g., place of birth, place of delivery, birth date (month/day), birth weight (in grams), gestation period, and prenatal care].
Relevant Policy Issues: Measurement of Health Status, Key Health Disparities, and Factors Contributing to Measured Health Disparities.
Data Type(s): Registry
Unit of Analysis: Individual
Identification of AI/AN/NA: Data are coded into the following categories:
  • White
  • Black
  • American Indian/Alaska Native (AI/AN)
  • Asian/Pacific Islander (microdata early than 2003 are subdivided into: Chinese, Japanese, Filipino, Hawaiian, Other API)

There are no detailed breakdowns for any of the Asian/Pacific Islander subgroups after 2002. Please see the NVSS Report Births: Final Data for 2003 for an explanation: http://www.cdc.gov/nchs/data/nvsr/nvsr54/nvsr54_02.pdf

Beginning 2003, data are available for selected states for multiple race reporting for the mother and the father. As of the 2004 data year, 15 states reported multiple race responses to NCHS. Because most states do not report multiple race, it is necessary to bridge the multiple race responses to single race, following a special algorithm developed by NCHS in cooperation with the Census Bureau and with support from the National Cancer Institute. A large proportion of births to American Indian and Hawaiian women in particular are to women reporting more than one race. Detailed verbatim and checkbox entries for multiple race persons are available on the natality files by request.

AI/AN/NA Population in Data Set: Total number of births registered in the United States in 2004: 4,112,052
AI/AN registered births in 2004: 43,927
Geographic Scope: The geographic scope of the data is national. Geographic areas identified are state, county, city (if more than 100,000 population), standard metropolitan statistical area (SMSA), and metropolitan/nonmetropolitan counties. Additional analyses are possible by state, county, city (if more than 100,000 population), standard metropolitan statistical area (SMSA), metropolitan/nonmetropolitan counties.
Date or Frequency: Data from all birth certificates are compiled into an annual file, except for the files for 1951-54, 1956-66, and 1968-71, when only a 50 percent sample was compiled, and 1967 when a 20- to 50-percent sample was compiled. Data for 1972-84 are based on 100 percent of births for selected states and a 50 percent sample for all other states.
Data Collection Methodology: Data from all birth certificates are compiled into an annual file, except for the files 1972, 1981 and 1982 when only a 50 percent sample was compiled.
Participation: Mandatory for NCHS to compile a national data set; state participation is based on the Vital Statistics Cooperative Program of the National Vital Statistics System.
Strengths: Data sets contain a large number of AI/AN respondents. Data are collected on key health issues. There are multiple years of data available.
Limitations: Of the Pacific Islander population groups, only Native Hawaiians as either a single- or multiple-race category can be separately identified in the microdata.
Access Requirements and Use Restrictions: The data set is available to the public on CD-ROM at no charge from births@cdc.gov or by contacting the office listed below.
Contact Information: Information on the Public Use Files and instructions for obtaining files can be located at http://www.cdc.gov/nchs/products/elec_prods/subject/natality.htm, or by contacting births@cdc.gov.
