Abstract

This report is based on 601 interviews with licensed Iowa drivers. Interviewing was done by telephone from Central Surveys' Shenandoah, Iowa offices from November 28, 1977 to December 7, 1977. Respondent selection was accomplished in a random manner from current telephone directories. The communities represented in the sample were also randomly selected from state voter registration files. Interviews were in clusters of five in each community. The original telephone number was tried three times on different days and at different times of day before a substitution was used. Interviewers were instructed to interview only licensed drivers. These potential respondents were further screened to be automobile drivers at least one time per week. Particular attention was paid to respondent age, and in most openings the interviewer was instructed to ask to interview the youngest available male of age 16 or more. Other age and sex quotas provided the following pattern as compared to U.S. Census Data Iowa, 1970.
