Current Dataset Release: December 6, 2018 Version

December 14, 2018
The variable label for VCF0424 should read “POLITICAL FIGURE THERMOMETER: Democratic Presidential Candidate” instead of indicating Republican Presidential candidate.
December 6, 2018
This release includes remaining 2016 data which were previously not available, including data for some post-election thermometers, paradata variables, candidate and typerace variables and interviewer description variables, among others. 2016 full religion coding and summary religion coding have also been included.
October 30, 2018
It has been discovered that 2012 data for defense spending variables VCF0549, VCF0550, VCF0843, VCF9081 and VCF9089 are not comparable with other years. The 2012 data in these variables will be removed in the next release.
October 2, 2018
It has been discovered that the 1988 question on preferential hiring of blacks (V880856) is comparable to VCF0867. Data for 1988 were not included in VCF0867 due to an error in the 1988 codebook documentation for V880856. The 1988 data will be added in the next CDF release.

May 31, 2018
In this release, 2016 data have been incorporated except for several variables for which data are not yet final from the 2016 Time Series Study. 2016 case id values in VCF0006 represent the revised 4-digit case ids which will be effected in the next release of the 2016 Time Series Study (old case IDS will be preserved in V160001a ‘Westat ID’). View a dual listing of new and old values at case level.

In addition, corrections have been made to 2012 data for variables VCF0107, VCF0108, VCF0128, VCF0148, VCF0148a, VCF0149, VCF0310, VCF0501, VCF0608, VCF0656, VCF0714, VCF0992, VCF1017, VCF9030b and VCF9030c. 2012 data have been removed from VCF9012, and, when 2012 ‘Most Important Problem’ open-end responses are coded, a new preparation of 2012 data for VCF9012 will be implemented. Finally, data have been removed from VCF0138 as non-comparable for years 2002-2012, and 2012 data have been removed from VCF9026 as non-comparable.

November 19, 2007
Due to an error in the technical specifications, the 2012 Web instrument did not include “Haven’t Thought Much About It” as an onscreen category for the Liberal-Conservative Self Placement question. As a result, data coded as “Haven’t Thought Much About It” in the Cumulative Data File for variable VCF0803 reflects face-to-face cases only.
July 21, 2015
Coding of Yes and No in VCF0501 (important differences between parties) has been reversed for 2012 and will be corrected in the next release. Thanks to Carey Stapleton for notification about this issue.
May 14, 2015
This release includes new cross-year race-ethnicity summary variables outlined in the ANES Project Memo “Plan to update race & ethnicity variables on the ANES CDF” (new variables VCF0105a, VCF0105b, and revised variable VCF0106).

Notes from Review of U.S. House Race Description (11 cases)
11 cases with new information describing type of House race in VCF0902, VCF0904, and/or VCF0905.
This additional information regarding correct description of congressional district House race is for notification only; the indicated variables will not be corrected because administration of the surveys occurred with the original and uncorrected information regarding type of House race.
