Content of the Tables
Sample size. The statistics in this report are based on samples of various sizes which have been adjusted to represent the total population. Depending on the content of the several tables, the data may come from the 5-, 15-, or 20-percent samples. The sample size on which each table is based is indicated in a headnote to the particular table. Because of sampling variability, data for a given characteristic may differ from one table to another when the tabulations are based on different sample sizes.
Census statistics date back to 1790 and reflect the growth and change of the United States. Past census reports contain some terms that today’s readers may consider obsolete and inappropriate. As part of our goal to be open and transparent with the public, we are improving access to all Census Bureau original publications and statistics, which serve as a guide to the nation's history.
