Summary
This study provides annual estimates of the population of all counties and county equivalents in the United States for the years 1971-1974. Also included are county-level estimates of the components of population change (births, deaths, and net migration) for the same years. County equivalents are parishes in Louisiana, census divisions in Alaska, and independent cities in Virginia and Missouri. The dataset was prepared by ICPSR from Current Population Reports published by the Census Bureau and originally compiled by the Census Bureau with the assistance of designated state agencies in the Federal/State Cooperative Program for Population Estimates. Several ICPSR geographic identification variables were included in the dataset to improve its utility and maintain the comparability of the present data with other county-level materials in the ICPSR archive. ICPSR also calculated some variable values that were missing from the Census Bureau reports.

In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Standardized missing values.
- Checked for undocumented or out-of-range codes.
