description: United States Historical Election Returns Series
description: The election data have been matched-merged and fixed-formatted within states. Because of the volume of data available for some states, it was necessary to store the election returns in more than one file per state.
County names have been standardized, including names for counties that have experienced name changes over time. In addition to the names, a county identification number was added to all county-level records. This number allows unique identification of all counties within states.
Data for elections to the office of United States representative have been collapsed to the whole-county level.
The election data files for each county contain the congressional district number of that county at the time of each election for the office of United States representative. When a county was divided into more than one congressional district, a code value indicating the number of congressional districts into which the county was divided was inserted in place of the congressional district number. It is thus possible to aggregate to the congressional district level all county-level election data (except in the case of split-district counties), and to perform the aggregations for the districts as they were constituted for any Congress.
Counties may have been assigned a congressional district number of zero if they were not in existence at the time of the election, did not report vote totals, or did not participate in that election.
For 1970 to 1990 election returns data, see GENERAL ELECTION DATA FOR THE UNITED STATES, 1970-1990 (ICPSR 0013).
Part 204, a listing of political party codes used in all data files, is an ASCII text file included as supplementary documentation. There is no actual codebook for this collection. Variable information is contained in the setup files. Some variable labels are cryptic. For example, the variable label V34="825 2 GOV 9001 VOTE" is interpreted as year of election/code for elected office/type of election/elected office/party code.
There are data for one race in Delaware from 1823 included in the collection, though this year is not reflected in the title.
