Study Content Highlights

This data file does not represent new content, but is the result of merging data from 3 previously-released studies. For additional information, please refer to the documentation of the source studies, the ANES 2000 Time Series Study, the ANES 2002 Time Series Study, and the ANES 2004 Panel Study.

Study Design Highlights

Respondents from the 2000 Time Series study were re-interviewed as a portion of the 2002 Time Series study sample, and some respondents interviewed in both 2000 and 2002 were interviewed again in a study which was specially designed for the purpose of re-interviewing them in 2004, the 2004 Panel study. A pre-election and a post-election survey were conducted for each of the two component Time Series studies, and a post-election survey was conducted for the 2004 Panel study. The table below displays respondents’ participation over the three studies. Rows correspond to combinations of completed interviews across the surveys.
