Poll Demographics

About this Poll
The findings in this report are based on a telephone survey of 2,000 California adult residents
interviewed from March 13th to 20th, 2007. Interviewing took place on weekday nights and weekend
days, using a computer-generated random sample of telephone numbers that ensured that both
listed and unlisted numbers were called. All telephone exchanges in California were eligible.
Telephone numbers in the survey sample were called up to six times to increase the likelihood of
reaching eligible households. Once a household was reached, an adult respondent (age 18 or older)
was randomly chosen for interviewing using the “last birthday method” to avoid biases in age and
gender. Each interview took an average of 18 minutes to complete. Interviewing was conducted in
English or Spanish. Accent on Languages translated the survey into Spanish with assistance from
Renatta DeFever. Schulman, Ronca & Bucuvalas, Inc. conducted the telephone interviewing.
We used recent U.S. Census and state data to compare the demographic characteristics of the
survey sample with characteristics of California’s adult population. The survey sample was closely
comparable to the census and state figures. The survey data in this report were statistically
weighted to account for any demographic differences.
The sampling error for the total sample of 2,000 adults is +/- 2 percent at the 95 percent confidence
level. This means that 95 times out of 100, the results will be within 2 percentage points of what
they would be if all adults in California were interviewed. The sampling error for subgroups is larger:
For the 1,542 registered voters, it is +/- 2.5 percent; for the 1,122 likely voters it is +/- 3 percent;
for the 498 Democratic presidential primary likely voters it is 5%; for the 374 Republican presidential
primary likely voters it is 5%. Sampling error is only one type of error to which surveys are subject.
Results may also be affected by factors such as question wording, question order, and survey timing.
