The Integrated Public Use Microdata Series (IPUMS) consists of thirty-eight high-precision samples of the American population drawn from fifteen federal censuses and from the American Community Surveys of 2000-2004. 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. Registration required: users are automatically registered when they agree to all conditions for use.
IPUMS-CPS provides integrated data and documentation from the March Supplement of the Current Population Survey (CPS) from the period 1962 to 2005. The harmonized CPS data are designed to be compatible with decennial census data in IPUMS-USA. Registration required: users are automatically registered when they agree to all conditions for use.

This site offers a variety of data visualization tools with varying degrees of interactivity. All resources are based on data they have gathered. One example is “Race in America: Tracking 50 years of Demographic Trends,” a tool that allows users to select a dimension upon which to build the chart and display the change over time by race. It also generates a table of the specified variable by year and race.
This collection offers datasets, including Arrest Data and Federal Criminal Case Processing Statistics, in formats that allow users to generate statistics, create tables of variables they select, and in some cases access “Quick Tables” of BJS-selected variables. There also is information on the study’s methodology, definitions of the variables, and other documentation.
