ANES is pleased to make available this current release of our Cumulative Data File. Those of you who are familiar with this dataset already know that the way the data and documentation are presented vary. These variations are due to changes in each new Time Series study, that are, in part, due to changes in ANES leadership. This release is no exception. The following are modifications for this new release:
- A decision was made for the 2012 Time Series to change the format of our documentation. Variable-level annotation for the CDF is taken from the Time Series codebooks, so there are some differences for 2012.
- A decision was made to change the policy regarding the use of inap. codes, so again you will notice some differences.
- Open ended responses have not yet been coded for the 2012 Time Series study. CDF variables representing coded data from 2012 Time Series open-end questions are forthcoming.
- In the course of preparing the CDF file, additional analyses uncovered some necessary corrections to the 2012 Time Series data. These corrections have been accounted for in the CDF file and will be corrected correspondingly in a forthcoming release of the ANES 2012 Time Series Study data. The required corrections will be noted on that study’s errata page.
- Questions for respondent race changed significantly in 2008 and 2012. A full and detailed review of the CDF respondent race variables is currently underway, which will result in new and better summary variables. In the interim, we are providing the 2008 and 2012 race and ethnicity variables for researchers who may want access to all available race data from all years in a single file. It is expected that the revised race and ethnicity variables will be available later this year, and will be announced on our website and on Twitter.
It is our hope that you will find that some of these modifications have made the CDF easier to use. Please let us know if you have any questions or comments.
