SDA Test Data


The SDA test data file is extracted from the 1986 Race and Politics Survey, a random-digit telephone survey of residents of the San Francisco-Oakland metropolitan area.

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.
