Sample Design of the Constituents of the Five Federal Agencies
This survey of constituent groups from five federal agencies was conducted through telephone interviews under the direction of Princeton Survey Research Associates between January and April 1999. The agencies included in the survey are the Internal Revenue Service (IRS), Social Security Administration (SSA), Food and Drug Administration (FDA), Environmental Protection Agency (EPA), and Federal Aviation Administration (FAA). The specific constituent groups interviewed are outlined below.
For samples of individuals, random-digit dialing was used to randomly select households within the continental US. At each household that agreed to be interviewed a short screening questionnaire was administered to determine whether anyone in the household qualified for the survey.
Samples of business leaders were randomly selected by firm from the Dun & Bradstreet nationwide listing of US firms. Advocacy groups were chosen from the listing of nonprofit groups compiled by the National Center for Charitable Statistics.
To maximize the representativeness of the samples, interviewers made multiple attempts and accommodated appointments at each randomly selected number before determining an individual was unreachable. For all samples, when someone refused an interview he or she was called back at least once with a specially trained interviewer in attempt to convince the respondent to participate.
