Our History

For decades, CQ Press—and its former parent company, Congressional Quarterly—has published a wealth of data on all aspects of American government. For years, this data was regularly published in print following consistent methodologies and often by the same person or group of people. Beginning in the early 2000s, CQ Press began digitizing this data and housing it in advanced databases. These databases allowed novice and advanced researchers alike to manipulate data in new and exciting ways that previously would have required expertise and extensive keying from print sources.

U.S. Political Stats builds on this legacy and a continued dedication to providing users with the tools and content they need to carry out in-depth research on government institutions and public policy.

Our Platform

U.S. Political Stats allows users to visualize data in the form of series over time—in tables, maps, pie charts, bar charts, and line graphs—and download that data either in small amounts or in bulk, using the Export Center. The visualization and comparison functionality is easy to use, engages novice researchers, and encourages them to draw unique insights from the data. Data within and between completely different areas of political science can be easily compared, which enables students to draw interesting correlations for papers or class assignments. More advanced researchers are encouraged to use these functions as well, but can defer to the Export Center for bulk spreadsheets, ideal for use in third party statistical programs like SPSS.

In U.S. Political Stats, users can:

  • Create custom data series based on variables of their choosing.
