National Medical Expenditure Survey, 1987: Survey of American Indians and Alaska Natives, Round 1 Person-level File [Public Use Tape 11] (ICPSR 9689)

Principal Investigator(s): United States Department of Health and Human Services. Agency for Health Care Policy and Research


The Survey of American Indians and Alaska Natives (SAIAN) is one of three major components of the 1987 National Medical Expenditure Survey (NMES). (The other two components are the Household Survey and the Institutional Population Component.) The SAIAN was designed in collaboration with the Indian Health Service (IHS), and used the same data collection instruments, interview procedures, and time frame as the Household Survey component. However, the SAIAN differed from the Household Survey in several respects. The SAIAN sample was interviewed only three times and was not given the supplements on long-term care, caregiving, and care-receiving. Also, SAIAN respondents were asked additional questions on topics such as use of IHS facilities and traditional medicine, and were given a modified self-administered questionnaire with separate versions for adults and children. Interviewers for the SAIAN were mainly American Indians or Alaska Natives, and about 40 percent of the interviews were conducted entirely in the native language of the respondent. Public Use Tape 11 contains person-level data from Round 1 only, focusing on demographics, household composition, employment, and health insurance.

Data Collection Notes:

The principal investigator notes that the data in Public Use Tape 11 are released prior to final cleaning and editing, in order to provide prompt access to the NMES data by the research and policy community. The racial/ethnic distribution includes American Indians (N = 5,734), Alaska Natives (N = 629), Whites (N = 647), and other (N = 48). The age distribution is 0-22 years (N = 3,485), 23-54 years (N = 2,718), 55-64 years (N = 435), and 65+ years (N = 433). Additional documentation including data collection instrument, data collection methods, and variance estimation procedures are available from ICPSR on request. This collection is superseded by NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: SURVEY OF AMERICAN INDIANS AND ALASKA NATIVES, POPULATION DATA, DATA FROM THE HEALTH STATUS QUESTIONNAIRE AND ACCESS TO CARE SUPPLEMENT, AND EXPENDITURES AND SOURCES OF PAYMENT DATA [PUBLIC USE TAPE 37] (ICPSR 6490).


Sample:    Multistage area probability design, using an Indian Health Service frame of counties with eligible individuals. An initial screening interview was completed in 13,700 dwelling units in those counties, yielding 1,950 households with at least one (self-defined) eligible person responding for the full year. Data were collected on 7,071 persons in the eligible dwelling units, of whom 6,557 also met criteria for person-level eligibility.
