United States Microdata Samples Extract File, 1940-1980: Demographics of Aging (ICPSR 8353)
Principal Investigator(s): Inter-university Consortium for Political and Social Research
This is an extract of the decennial Public Use Microdata Sample (PUMS) released by the Bureau of the Census. Because the complete PUMS files contain several hundred thousand records, ICPSR has constructed this subset to allow for easier and less costly analysis. The collection of data at ten year increments allows the user to follow various age cohorts through the life-cycle. Data include information on the household and its occupants such as size and value of dwelling, utility costs, number of people in the household, and their relationship to the respondent. More detailed information was collected on the respondent, the head of household, and the spouse, if present. Variables include education, marital status, occupation and income.
These data are available only to users at ICPSR member institutions. Because you are not logged in, we cannot verify that you will be able to download these data.

Scope of Study
Geographic Coverage: United States
Universe: For 1960-1980, all PUMS records for persons 18 and over. For 1940 and 1950, all sample line records.
Data Types: survey data
Data Collection Notes:
The stratified sample has unequal sampling rates across strata and requires the use of weights for analyses using more than one stratum. The epsem sample was selected in a second stage from the stratified sample and used compensating sampling rates within each stratum so that the overall probability of selection for each person is equal. The person level weight for use with the stratified sample and the household weight to be used with the epsem sample are included in the data file.
Conducted by the United States Department of Commerce, Bureau of the Census.
Sample: Stratified sample of adults contained in the Public Use Microdata Sample. Approximately 500 records were drawn from each of 28 sex/age/race strata. Additionally, an equal probability (epsem) sample was drawn from the stratified sample.
