This data collection describes the social conditions of the older population of the United States at the turn of the century. Detailed information, extracted from the 1900 United States Census manuscript schedules, is provided on household composition and family structure for each sampled older person. Ecological characteristics of the county of residence, e.g., the percentage of the county's population that is foreign born, are provided for most sampled older persons. In addition, occupational and ethnic characteristics of family heads appearing on the same sampled census page as the older person (on census pages grouped by street location) are reported.

Age distribution: 55-64 (N is 2,002), 65-74 (N is 2,203), 75-84 (N is 690), 85 and older (N is 108). The values for the weighting variable "Weighting Factor II" are incorrect. The SPSS statements that will correctly weight the sample are given in the codebook.
The data were extracted, between 1976 and 1978, from the manuscript census schedules of the United States census for 1900, located in microfilm form in the Chicago regional branch of the national archives. A total of 5,003 persons aged 55 and older were sampled from the universe of non-institutionalized persons living in the contiguous 48 states and the District of Columbia. All items from the 1900 census were utilized.
A multistage, stratified probability sample resulting in 100 primary sampling units (PSUs) was taken from the universe. Stratified sample of 56 counties (excluding cities with populations of 25,000 or more) and 44 urban Primary Sampling Units (PSUs). Cities with populations over 25,000 were triple-sampled. Sample members were drawn from clusters defined by manuscript census pages. Please refer to the codebook for details.

There are 163 variables on 5,003 cases. Variables include month and year of birth, sex, race, household status and composition, marital status, age, birthplace, occupation, and neighborhood information.

ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
The urban and rural sample fractions and age category fractions were weighted based on the proportions in the population reported in the 1900 census. The variable "Weighting Factor II" (VAR0163) contains these weights, but the principal investigators reported that the weights were copied onto the tape incorrectly. Please refer to the codebook for details.
