Poll Demographics

About this Poll

The findings in this report are based on a telephone survey of 2,003 California adult residents interviewed from Sept. 4 to 11, 2007.
The sampling error for the total sample of 2,003 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
1,511 registered voters, it is +/- 2.5 percent; for the 1,045 likely voters, it is +/- 3 percent; for the 455
Democratic presidential primary likely voters and the 353 Republican presidential primary likely voters, it
is +/- 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.
