The theme of the survey is "Orange County: A Change of Course."
The 1988 Orange County Annual Survey examines previous trends and explore
new topics. The survey is designed to provide a comprehensive analysis of
county issues. The sample size is 1,003 Orange County adult residents.

The Orange county Annual Survey was directed by Mark Baldassare, a
professor of social ecology at UC Irvine. For the survey, 1,003 adult
Orange County residents were interviewed by telephone Sept. 6 to 22. In
Orange County, where more than 97 percent of households have telephones,
this method of interview gives highly representative data.
Interviewing was conducted on weekend days and weekdaynights, using a
random sample of 4,500 listed and unlisted telephone numbers. These
telephone numbers were generated by computer from a list of working blocks
of telephone exchanges. The telephone sample was generated by Pijacki and
Associates of Shoreham, N.Y. The field work was conducted at the Center
for Survey Research by UCI's Public Policy Research Organization.
Of the telephone numbers called, 22 percent resulted in completed
interviews and 13 percent were refusals. The completion rate for the
survey (completions divided by completions plus refusals) was 62 percent.
Other telephone outcomes included the following: 21 percent disconnected
numbers; 15 percent businesses and government agencies; 7 percent
persistent no answer; 2 percent persistent telephone answering machines; 2
percent computer lines; and 2 percent persistently unavailable
respondents. Three percent were not completed because of language
problems, including Spanish and other non-English speaking households, and
hearing impairment.
Within a household, respondents were chosen for interview using the
Troldahl-Carter method. This method randomly selects a household member
from a grid that includes information on the number of adult household
members and the number of adult men in the household.
Each interview contained 90 questions and took an average of 17 minutes to
complete. Length of interview ranged from a low of 10 minutes to a high of
30 minutes.
The surveys were designed in three stages over several months. In the
first stage, UCI undergraduate students conducted face-to-face interviews
on Orange county topics with randomly selected adult residents. The second
stage involved feedback on questions and topics from the annual
survey's steering Committee, Advisory committee and colleagues. The
final stage included pre-tests, followed by final revisions of the
questions.
The interview began with questions about housing, consumer confidence and
perceptions of life in Orange County. These were followed by questions on
growth, traffic and transportation issues. Later in the interview, we
turned to the topics of charities, public education and child care. The
conclusion of the survey was devoted to questions about work and commuting
patterns, personal characteristics, household status and political
views.The survey's validity was checked by comparing the
sample's characteristics to available information on Orange
County's population. We compared the 1987 survey results to the 1980
U. S. Census, previous annual surveys and other recent survey data. Age,
income and other demographic features of our sample were comparable with
those noted in other studies.For data analyses, we statistically weighted
the sample to represent the actual regional distribution of Orange County
residents.
Other efforts were made to correct for possible errors in the process of
interviewing and data processing. Approximately 10 percent of the
completed interviews were verified through callbacks. All questionnaires
were checked by the interviewer supervisor immediately after completion.
Finally, keypunched data were double-checked for all cases in the survey
sample.The sampling error for this survey is +/-3 percent at the 95
percent confidence level. This means that 95 times out of 100, the results
will be within 3 percentage pointsof what they would be if all adults in
Orange county were interviewed. The sampling error for any subgroup would
be larger.
Sampling error is just one type of error to which surveys are subject.
Results may also influenced by factors such as question wording, survey
timing and other aspects of survey design.
