Post/Univision/TRPI Poll Methodology

Wednesday, October 27, 2004; 10:45 PM

This telephone survey was sponsored by The Washington Post, the Univision Spanish-language television network and the Tomas Rivera Policy Institute (TRPI), an independent think tank affiliated with the University of Southern California. Each organization bears sole responsibility for the work that appears under its name. Interviewing was conducted by Interviewing Service of America of Van Nuys, Calif.

A total of 1603 randomly selected Latino registered voters were interviewed by telephone October 4 - 16, 2004, in the 11 states with the largest Latino electorates, including: California, Texas, Florida, New York, Arizona, Illinois, New Mexico, New Jersey, Colorado, Virginia and Massachusetts. Together, these states are home to 88 percent of the Latino electorate. Offical lists of registered voters were obtained from the 11 states. To identify voters of Hispanic heritage, the last names of voters were matched against a U.S. Census Bureau file containing the 12,215 most common Latino surnames. Margin of sampling error for overall results is plus or minus 3 percentage points, and slightly larger for subsamples.
