This data collection was produced by CBS News, New York, NY.
Sample: A variation of random-digit dialing (RDD) using primary sampling units (PSUs) was employed, consisting of blocks of 100 telephone numbers identical through the eighth digit and stratified by geographic region, area code, and size of place. Phone numbers were dialed from RDD samples of both standard land-lines and cell phones. Within households, respondents were selected using a method developed by Leslie Kish and modified by Charles Backstrom and Gerald Hursh (see Backstrom and Hursh, SURVEY RESEARCH. Evanston, IL: Northwestern University Press, 1963).
Weight: The data contain weight variables that should be used in analyzing the data. According to the CBS News Web site, the data were weighted to match United States Census Bureau breakdowns on age, sex, race, education, and region of the country. The data were also adjusted for the fact that people who share a telephone with others have less chance to be contacted than people who live alone and have their own telephones, and that households with more than one telephone number have more chances to be called than households with only one telephone number.
Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Performed consistency checks.
- Created variable labels and/or value labels.
- Checked for undocumented or out-of-range codes.
