DOI

10.17605/OSF.IO/8PW65

Summary

The Alaska and Hawaii Supplement to the U.S. Religious Landscape Survey obtained telephone interviews with representative samples of 200 adults living in Alaska and 201 adults living in Hawaii. The survey was conducted by Princeton Survey Research International. Interviews were done in English by Princeton Data Source, LLC from March 13 to March 30, 2008. Statistical results are weighted to correct known demographic discrepancies. The margin of sampling error is +/- 7.5 percentage points for results based on Alaska respondents and +/- 8.5 percentage points for results based on Hawaii respondents.

Collection Procedures

The survey was conducted by Princeton Survey Research International. Interviews were done in English by Princeton Data Source, LLC from March 13 to March 30, 2008. Statistical results are weighted to correct known demographic discrepancies. The margin of sampling error is +/-7.5 percentage points for results based on Alaska respondents and +/-8.5 percentage points for results based on Hawaii respondents.

As with the main survey, as many as 10 attempts were made to contact every sampled telephone number. 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. In each contacted household, interviewers asked to speak with the youngest adult male currently at home. 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.

Sampling Procedures

The sample for the supplemental survey was designed to represent all landline telephone households in Alaska and Hawaii. The telephone sample was provided by Survey Sampling International, LLC (SSI) according to PSRAI specifications. The sample was drawn using standard list-assisted random digit dialing (RDD) methodology. Active blocks of telephone numbers (area code + exchange + two-digit block number) that contained three or more residential directory listings were equally likely to be selected; after selection two more digits were added randomly to complete the number. This method guarantees coverage of every assigned phone number regardless of whether that number is directory listed, purposely unlisted or too new to be listed. After selection, the numbers were compared against business directories and matching numbers purged.

Weighting

Each state's sample was weighted to match parameters for sex, age, education and race/ethnicity. These parameters came from a special analysis of the U.S. Census Bureau's 2006 Annual Social and Economic Supplement that included all households in Alaska and Hawaii that had a telephone.

Response Rate

The response rate estimates the fraction of all eligible respondents in the sample that were ultimately interviewed. At PSRAI it is calculated by taking the product of three component rates:

1. Contact rate - the proportion of working numbers where a request for interview was made - of 76 percent

2. Cooperation rate - the proportion of contacted numbers where a consent for interview was at least initially obtained, versus those refused - of 36 percent

3. Completion rate - the proportion of initially cooperating and eligible interviews that were completed - of 88 percent

Thus the response rate for supplemental survey of Alaska and Hawaii was 24 percent.

Modified Race Question

The original Landscape Survey questionnaire was used for these supplemental interviews. Minor wording changes were made to the race question to account for the unique racial makeup of Alaska's and Hawaii's populations.
