Results are based on a random-digit-dialing telephone survey of 2,743 English-speaking non-institutionalized adults (aged 18 years and older) in the 50 states and the District of Columbia. Two versions of the questionnaire were sequentially administered to the sample. Version 1 had 1,374 respondents and Version 2 had 1,369 respondents. Households were selected from a nationally representative single-stage sample of telephone numbers generated from the GENESYS system. The eligible respondent in a household was selected using the most-recent birthday method. The survey was conducted by a contractor during May 14 - September 24, 2002. A response rate of 30 percent was obtained; the rate was calculated per the Response Rate 3 (RR3) formula by the American Association for Public Opinion Research. Results have been weighted to adjust for number of land phone lines in a household, number of adults in a household, and Census distributions of gender, race/ethnicity, and education in the 50 states and District of Columbia.
The number of respondents who answered a question, or sample size ("n"), is shown for each question.An asterisk (*) denotes a percentage value between zero and one. Row or column percentages may not sum to 100 due to rounding, multiple responses, or both.
