title: Archival Version

description: Please read the <strong>collection notes</strong> below; there are many points to be aware of for this collection prior to analysis.
This collection of historical election data contains state
files that list county-level returns for over 90 percent of all
elections to the offices of president, governor, United States
senator, and United States representative from 1824 through 1968. The
data files include returns for all parties and candidates (as well as
write-in and scattering votes if available for individual states), and
for special elections as well as regularly-scheduled contests. Over
1,000 individual party names and many additional unaffiliated
candidates are included.
description: The purpose of this study is to capture United States county-level historical election returns over the time period of 1824 to 1968.
description: Variables within each dataset in this study contain variables capturing state code, county name, congressional district numbers over time, and county-level election returns.

description: Smallest Geographic Unit: United States Counties
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 election returns data from 1970 to 1990, see "General Election Data for the United States, 1950-1990 (ICPSR 13)."Dataset 32 is titled "Election Returns for Delaware, 1823-1876" and includes data from 1832, while the study title "United States Historical Election Returns, 1824-1968" does not include the year 1823.In datasets 126, 127, 128 and 129 for Georgia, the county identification code for Jackson county is 1510 in the data, however, it should be 1570. Users are advised when analyzing these data by county to either use the county names in variable <strong>V2</strong> or recode the county identification in variable <strong>V3</strong> from 1510 to 1570 for Jackson county.For all data files, <strong>V1</strong> is labeled "ICPR STATE CODE." This reflects previously used institutional title. Users may note difference from currently used acronym, ICPSR, since title change.
