<\/figure>\n<\/p>\n\nThe sample for this survey is a random digit sample of telephone numbers selected from telephone exchanges in the continental United States. The random digit aspect of the sample is used to avoid \u201clisting\u201d bias and provides representation of both listed and unlisted numbers (including not-yet-listed numbers). The design of the sample achieves this representation by random generation of the last two digits of telephone numbers selected on the basis of their area code, telephone exchange, and bank number.<\/p>\n\n
Sample was released for interviewing in replicates, which are representative subsamples of the larger sample. Using replicates to control the release of sample ensures that complete call procedures are followed for the entire sample.\u00a0 At least 10 attempts were made to complete an interview at sampled households.\u00a0 Calls were staggered over times of day and days of the week to maximize the chance of making contact with potential respondents. Each household received at least one daytime call in an attempt to find someone at home.\u00a0 In each contacted household, interviewers asked to speak with the youngest male currently at home.\u00a0 If no male was available, interviewers asked to speak with the youngest female at home. This systematic respondent selection technique has been shown to produce samples that closely mirror the population in terms of age and gender.<\/p>\n\n
Non-response in telephone interviews produces some known biases in survey-derived estimates because participation tends to vary for different subgroups of the population, and these subgroups are likely to vary also on questions of substantive interest. In order to compensate for these known biases, the sample data are weighted in analysis. The demographic weighting parameters are derived from a special analysis of the Census Bureau\u2019s March 2006 Annual Social and Economic Supplement Survey. This analysis produces population parameters for the demographic characteristics of adults age 18 or older, living in households that contain a telephone. These parameters are then compared with the sample characteristics to construct sample weights. The weights are derived using an iterative technique that simultaneously balances the distribution of all weighting parameters.<\/p>\n\n
PSRAI calculates a response rate as the product of three individual rates:\u00a0 the contact rate, the cooperation rate, and the completion rate.\u00a0 Of the residential numbers in the sample, 87 percent were contacted by an interviewer and 27 percent agreed to participate in the survey.\u00a0 Eighty-five percent were found eligible for the interview.\u00a0 Furthermore, 93 percent of eligible respondents completed the interview.\u00a0 Therefore, the final response rate is 22 percent.<\/p>\n\n
Following is the full disposition of all sampled telephone numbers:<\/p>\n\n
The results in this report are based on data from telephone interviews conducted by Princeton Survey Research Associates International between December 13, 2007 to January 13, 2008, among a sample of 2,252 adults, 18 and older.\u00a0 For results based on the total sample, one can say with 95% confidence that the error attributable to sampling
