STUDY DESIGN & CONTENT HIGHLIGHTS:
The ANES 2012 Direct Democracy Study collected public opinion data concerning ballot measures in 13 states: Arizona, Arkansas, California, Colorado, Florida, Massachusetts, Michigan, Missouri, North Dakota, Ohio, Oregon, South Dakota, and Washington.
Data were collected concurrently with the ANES 2012 Time Series study by asking Direct Democracy questions to Time Series respondents during (at the end of) the Time Series pre- and post-election interviews and by administering a separate Direct Democracy questionnaire to a supplemental sample of respondents. These supplemental respondents completed a subset of the Time Series questions. All respondents answered questions about ballot measures in their state, including voting on ballot measures, ease of understanding them, groups ballot measures would affect, groups campaigning for or against ballot measures, and evaluation of the use of ballot measures.
The estimated overall response rate (AAPOR RR3) is expected to be 1 or 2 percent.
Use the variables weight_pre and weight_post.
PRE-PROCESSING PRELIMINARY RELEASE:
The current dataset – released December 2013 – is a rough draft and contains errors.
Variables have inconsistent missing data codes, such as improper or
unlabeled distinctions among the categories for item nonresponse due to item refusal, technical error, an appropriate skip pattern, or an undifferentiated
missing data category. ANES staff will work to correct all errors and to make the data easier to use. Please tell ANES staff about any problems with the
data by sending email to firstname.lastname@example.org. Any future re-release of the dataset will contain error
corrections or other changes to improve accuracy and usability.
MERGING THE DATA WITH THE ANES 2012 TIME SERIES STUDY:
Many of the respondents who completed the Direct Democracy surveys also completed the ANES 2012 Time Series Survey. The case identification
variables on the two files do not correspond to the same individuals. Details on how to merge the Direct Democracy data with the 2012 Time Series data will
be made available in January, 2014.
