Roll call voting records for the United States House of Representatives and Senate through the 100th Congress are presented in this data collection. Each data file in the collection contains information for one chamber of a single Congress. The units of analysis are the individual members of the House of Representatives and Senate. Each record contains a member's voting action on every roll call vote taken during that Congress, along with variables that identify the member (e.g., name, party, state, and uniform ICPSR member number). In addition, the codebook provides descriptive information for each roll call, including the date of the vote, outcome in terms of yeas and nays, name of initiator, the relevant bill or resolution number, and a synopsis of the issue.
These data are available only to users at ICPSR member institutions. Because you are not logged in, we cannot verify that you will be able to download the data.
WARNING: Because this study has many datasets, the download all files option has been suppressed, and you will need to download one dataset at a time.

This collection is derived from UNITED STATES CONGRESSIONAL ROLL CALL VOTING RECORDS, 1789-1990 (ICPSR 0004), and differs from that collection in several ways. Codebooks have been standardized in format across all Congresses, and a number of discrepancies in members' identifying information (member identification number, party, etc.) have been corrected.
