ANES 2004 Time Series and Panel Contextual File (ICPSR 4294)

Principal Investigator(s): University of Michigan. Institute for Social Research. Center for Political Studies.


This study is part of the American National Election Study (ANES) Series, a time-series collection of national surveys fielded continuously since 1948, and designed to gather information on Americans' social backgrounds, enduring political predispositions, social and political values, as well as their perceptions and evaluations of political groups and candidates, opinions on questions of public policy, and participation in political life. The 2004 ANES auxiliary file of contextual data was created to provide a core of information for analysts interested in examining the 2004 general elections in a larger framework; thus, the dataset includes candidate biographical data, as well as information about past elections, expenditures, House and Senate member records and ratings, and district and state descriptions. The 436 records represent all of the United States Congressional Districts (and, for population description, the District of Columbia) and therefore may be used with both the ANES 2004 TIME SERIES STUDY [ICPSR 4245] and the ANES 2004 PANEL STUDY [ICPSR 4293].
