Summary View help for Summary
Designed to facilitate analysis of the status of Blacks around the turn of the century, this oversample of Black-headed households in the United States was drawn from the 1910 manuscript census schedules. The sample complements the 1/250 Public Use Sample of the 1910 census manuscripts collected by Samuel H. Preston at the University of Pennsylvania: CENSUS OF POPULATION, 1910 [UNITED STATES]: PUBLIC USE SAMPLE (ICPSR 9166). Part 1, Household Records, contains a record for each household selected in the sample and supplies variables describing the location, type, and composition of the households. Part 2, Individual Records, contains a record for each individual residing in the sampled households and includes information on demographic characteristics, occupation, literacy, nativity, ethnicity, and fertility.

The data contain blanks and alphabetic characters. This oversample can be combined with the 1/250 Public Use Sample by differential weighting of households (or individuals) by county of enumeration as described in the User's Guide.

Sampling was carried out using computer software that randomly selected households based on the manuscript census microfilm reel number, sequence, and page and line number, with two different sampling fractions. Counties in Maryland, Kentucky, and Texas were sampled using a 0.01 sampling fraction, while a 0.005 sampling fraction was employed in Virginia, North Carolina, Florida, Tennessee, and Arkansas. In Louisiana, both fractions were utilized to test optimum sampling fractions.

Manuscript census records for 1910 from counties with at least 10 percent of the population African-American (Negro, Black, or Mulatto) located in nine states where a large number of counties had at least this same proportion of African-Americans (Maryland, Virginia, North Carolina, Florida, Kentucky, Tennessee, Arkansas, Louisiana, and Texas). The four states with the largest population of Blacks (South Carolina, Alabama, Mississippi, and Georgia) were excluded from the oversample because the 1/250 Public Use Sample (referred to above) provided sufficient cases for most analyses.
