Summary View help for Summary

The 1986 Bay Area Race and Politics Survey was a random-digit telephone survey of residents of the San Francisco-Oakland metropolitan area. The questions focused primarily on issues of race, politics, and prejudice. There were also several items on the role of women. The survey included many experimental variations in question wording that were developed specifically for this study. This was the first survey to incorporate major substantive experiments into computer-assisted interviews. The Survey Research Center of the University of California, Berkeley, conducted the survey from August through October 1986, using the CASES system for computer-assisted telephone interviewing. Interviews were completed with 1,113 persons, and the response rate was 68.1 percent.

Sample View help for Sample

Random digit telephone sample based on all prefixes in the 415 area code (at that time). The prefixes corresponding to the cities of Oakland and Richmond were oversampled by a factor of 2, in order to increase the number of African American respondents. Within the selected households, all English-speaking adults aged 18 and older were enumerated, and one adult was selected at random to be interviewed.

2022-03-08 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:

  • Created online analysis version with question text.
  • Performed recodes and/or calculated derived variables.

Weight View help for Weight

The data file includes a variable 'CASEWT', which adjusts for unequal probabilities of selection between respondents. There are three components to this weight variable:

  1. Since residents of Oakland and Richmond were oversampled by a factor of two, the weight for respondents from those cities included a factor to adjust for that oversampling. If S is the stratum factor, S is .5 for respondents from Oakland and Richmond; otherwise, S is 1. .
  2. Since only one adult was selected from each household, the probability of selection of each adult is 1/P, where P is the number of adult persons in the household. The corresponding weight factor for each respondent, consequently, is P. .
  3. Those households with more than one telephone line have a greater chance of being selected. The probability is proportional to T, where T is the number of lines. The corresponding weight factor is 1/T.

The sampling weight for each case on the data file (CASEWT) is k*S*P/T, where k is a constant to scale the weight so that the weighted number of cases equals the unweighted number of cases (1,113).
