About this Poll

Findings in this report are based on a survey of 2,002 California adult residents, including 1,802 interviewed on landline telephones and 200 interviewed on cell phones. Interviewing took place on weekday nights and weekend days between October 10 and 17, 2010. Interviews took an average of 17 minutes to complete.

The sampling error, taking design effects from weighting into consideration, is ±3.1 percent at the 95 percent confidence level for the total sample of 2,002 adults. This means that 95 times out of 100, the results will be within 3 percentage points of what they would be if all adults in California were interviewed. The sampling error for subgroups is larger: For the 1,582 registered voters, it is ±3.4 percent; for the 1,067 likely voters, it is ±3.5 percent. 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.
