Dataset: IPUMS - Integrated Public Use Microdata Series
Description: The IPUMS consists of twenty-seven high-precision samples of the American population drawn from fourteen federal censuses. Some of these samples have existed for years, and others were created specifically for this database
The twenty-seven samples, which span the censuses of 1850 to 2000, collectively comprise our richest source of quantitative information on long-term changes in the American population. However, because different investigators created these samples at different times, they employed a wide variety of record layouts, coding schemes, and documentation. This has complicated efforts to use them to study change over time. The IPUMS assigns uniform codes across all the samples and brings relevant documentation into a coherent form to facilitate analysis of social and economic change.
Time period: 1850-2000 (Updated after each census)
