ABC News/Washington Post Poll, April 2008

computer-assisted telephone interview (CATI) The data available for download are not weighted and users will need to weight the data prior to analysis. The variables PCTBLACK, PCTASIAN, PCTHISP, MSAFLAG, CSA, CBSA, METRODIV, NIELSMKT, BLOCKCNT, and ZIP were converted from character variables to numeric. To preserve respondent confidentiality, codes for the variables FIPS (FIPS County) and ZIP (ZIP Code) have been replaced with blank codes. System-missing values were recoded to -1. The CASEID variable was created for use with online analysis. Value labels for unknown codes were added in variables MSA, CSA, CBSA, and METRODIV. The variable CBSA contains diacritical marks. The data collection was produced by Taylor Nelson Sofres of Horsham, PA. Original reports using these data may be found via the ABC News Polling Unit Web site and via the Washington Post Opinion Surveys and Polls Web site. Variables MSA, CSA, and CBSA contain values for which there are no known codes.
