ANES 2004 Time Series Study (ICPSR 04245)

Alternate Title:  American National Election Study, 2004: Pre- and Post-Election Survey

Principal Investigator(s):


This study is part of the American National Election Study (ANES), a time-series collection of national surveys fielded continuously since 1952. The American National Election Studies are designed to present data on Americans' social backgrounds, enduring political predispositions, social and political values, perceptions and evaluations of groups and candidates, opinions on questions of public policy, and participation in political life. The 2004 ANES data consists of a time series study conducted both before and after the 2004 presidential election in the United States. It entailed both a pre-election interview and a post-election re-interview. A freshly drawn cross section of the electorate was taken, yielding 1,212 cases. Like its predecessors, the 2004 ANES was divided between questions necessary for tracking long-term trends and questions necessary to understand the particular political moment of 2004. The study maintains and extends the ANES time-series 'core' by collecting data on Americans' basic political beliefs, allegiances, and behaviors: aspects of political belief and action so basic to the understanding of politics that they are monitored at every election, no matter the nature of the specific campaign or the broader setting. The study also carried topical and study-specific instrumentation. Questions covering issues prominent in 2004 addressed job outsourcing, private investment of Social Security funds, and President Bush's tax cut. Americans' views on foreign policy, the war on terrorism, and the Iraq War and its consequences were also addressed. In addition, the study carried expanded instrumentation on inflation, immigration, gender politics, and gay and lesbian politics. It also extended the experiment on the measurement of voter turnout that began in 2002. The survey included information on respondent age, education level, political affiliation, race/ethnicity, marital status, and family composition.
