Bexar County voters say YES to Fluoride

The San Antonio Survey 2000 (SAS 2000) is an annual survey conducted by the University of Texas at San Antonio students in the combined research methods courses of political science, sociology, criminal justice and public administration, in conjunction with the University's Metropolitan Research and Policy Institute. The purpose of the survey is to give research methods students experience in survey research as well as to measure the attitudes and perceptions of San Antonians on important topics of the day. Surveys were conducted during the weeks of October 9-25th, 2000.

The SAS 2000 data are based on a random probability sample of individuals with telephones and consist of eight hundred and forty-two (842) responses from the Bexar County metropolitan area. A split sample design produced 389 completed responses from a random sample of registered voters who had voted in any one of the last five elections, and 388 from a random sample of adults in San Antonio with telephones. The standard error of the entire sample is +/- 3.4% and the error for each split sample is +/- 4.8% with a 95 percent confidence level.
