The Voting Scores for Members of the United States Congress series was developed by ICPSR from the Congressional Quarterly Almanac for the period 1945-1982. The data provide information on the voting scores of members of Congress who served at any time in the period 1946-1982, from the second session of the 79th Congress to the second session of the 97th Congress. Voting scores are computed for each Senator and Representative for each session of the Congress (except for the 79th, 80th, 96th, and 97th Congresses). Variables include voting participation, which is an indicator of the member's attendance only, partisan voting, bipartisan voting, conservative coalition voting, presidential issues voting, federal role voting, and interest group voting. The individual member of Congress is the unit of analysis.
