Yearly W-NOMINATE Scores

The files below are text files. Each file contains W-NOMINATE scores by year for the indicated House/Senate. For Houses 76 to 91 there were insufficient roll calls to reliably estimate a 2nd dimension.

As we explain in our book Congress: A Political-Economic History of Roll Call Voting, the first dimension for this period can be interpreted as a standard liberal-conservative left-right government intervention in the economy dimension. The 2nd dimension picks up the conflict between North and South on Civil Rights.

For an explanation of how the data is organized and formatted read this text file.
