Louis Harris Data Center

Since 1965, the Odum Institute has operated the Louis Harris Data Center, the national depository for publicly available survey data collected by Louis Harris and Associates, Inc. More than 1,000 Harris Polls from as early as 1958 are archived at the Center and contain over 160,000 questions asked of more than 1,200,000 respondents. Respondent groups range from national cross-section samples to such special populations as Vietnam veterans, Hispanics, teenagers, and the elderly. The surveys also cover a diverse range of topics, such as aging, environmental issues, leisure and the arts, business, foreign affairs, presidential ratings, health care, attitudes toward government, and crime. Many questions have been repeated over time, allowing researchers to track changes in opinions and attitudes. For more information, contact Jonathan Crabtree at odumarchive@unc.edu or 919-428-6112.
