Summary
This collection contains county-level returns for elections to the United States presidency and to the United States House of Representatives for the years 1840 to 1972. The variables for the presidential vote include the percentages of ballots cast for major and "significant" minor party candidates (with residual votes collapsed into an "other" category), total numbers of votes for all candidates in an election, and estimates of voter turnout in the presidential elections. There are similar variables for the congressional vote except that returns are reported for parties and not for candidates. Congressional district numbers are also reported for each county for every election.

Data Collection Notes
Some of the data in this collection were compiled from ICPSR 0003. Since the time of this data collection's first release, ICPSR 0003 has been updated and is available as ICPSR 2896 (HISTORICAL, DEMOGRAPHIC, ECONOMIC, AND SOCIAL DATA: THE UNITED STATES, 1790-2000). Users of the current data collection should check ICPSR 2896 for specific information about updates that may affect the analysis of the data in this collection.
The variable V3 (COUNTY IDENTIFICATION NO) is not necessarily equivalent to the FIPS code for a given county.

Version History
2005-01-27 A processor's note has been added to the codebook to explain an apparent discrepancy between the 'V3 -- COUNTY IDENTIFICATION NO' variable and FIPS, which are in fact independent of one another. Also, the codebook has been converted to PDF form.
2006-11-13 The codebook has been updated to reflect revisions made to the processing notes, which now include an explanation for computing partisan and voter turnout percentages.
