AMERICAN NATIONAL ELECTION STUDY, 2000: PRE- AND POST-ELECTION SURVEYS During the early spring of 2001 the National Election Studies staff prepared a comprehensive version of the 2000 American National Election Study. The number of cases in this file, 1807, includes all respondents from the 2000 Pre- and Post-Election surveys. 1881 variables are produced by default using the data definition files provided with the raw data for creation of SAS and SPSS system files. The codebook contains documentation for variables beginning with identification variables which provide the NES VERSION NUMBER (version number of the data file), NES DATASET NUMBER (number of this dataset), and ICPSR study number.
