American National Election Studies (ANES)
(Access: ANES Web site)
ANES conducts national surveys of the American electorate in election years and carries out research and development work through pilot studies. The longevity of the ANES time-series (begun in 1948) greatly enhances the utility of the data, since measures can be pooled over time, and both long-term trends and the political impact of historical events can be identified. The ANES includes three study types:
-
Time Series Studies, conducted around each national election. In presidential election years, the study is typically conducted both before and after the election (that is, a pre-election study and a post-election study), while for congressional election years the study has typically been conducted only after the election (a post-election study).
-
Pilot Studies, normally conducted in the 'off-years' when there is no national election. These studies are designed to test new, or refine existing, instrumentation and study designs, all in order to improve the Time Series Studies.
-
Other Major Data Collections, which include ad hoc stand alone studies such as the Senate Election Studies and the 1982 Methods Comparison Study, as well as the panel studies which span individual Time Series studies.
ANES data are also available from the ICPSR.
