Charles Stewart's Congressional Data Page

 

The purpose of this page is to begin accumulating hyperlinks in one place to various sites around the country that house data relevant to studies of Congress, legislatures in general, and all the rest. My preference is to link to (more or less) ready-to-use data sites. Of course, no warranties are made, implied or explicit, about this data. Your mileage may vary.

The data to which this page points have been collected through the work of many, many dedicated people working many, many hours. Their being made available here is one provision of a public good. Please let the original data collectors know you're using their work. Also, please cite the data as the authors wish to be cited.

House Committee Request Data

Collector: Scott A. Frisch and Sean Q Kelly

Contact: Sean Kelly

Preferred citation style:Frisch, Scott A. and Sean Q Kelly. 2007. House Committee Request Data, 80th-103rd Congress. [Access information].

Description:(The following is taken from the web page): Our committee assignment request data are now available. As the map to the left indicates a tremendous amount of effort went in to the collection of these data that include committee requests for Democratic and Republican members of the House between the 80th and 103rd Congresses (with only a few gaps). With the publication of our book Committee Assignment Politics in the U.S. House of Representatives (University of Oklahoma Press 2006) we want to make these data available to our colleagues. It is our feeling that in many cases using committee assignment data provides an inaccurate and/or incomplete understanding of how committees and committee memberships shape and constrain the behavior of members of Congress.
