Poll Demographics

About this Poll
The findings in this report are based on a Field Poll survey completed June 3-13, 2011 among a random sample of 950 registered voters in California, which included interviews with 322 registered Republicans.

Sampling error estimates applicable to the results of any probability-based survey depend on sample size as well as the percentage distribution being examined. The maximum sampling error estimates for results based on the overall registered voters sample is +/- 3.3 percentage points at the 95% confidence level, while findings based on the Republican voters have a sampling error of +/- 5.7 percentage points.

The maximum sampling error is based on results in the middle of the sampling distribution (i.e., percentages at or near 50%). Percentages at either end of the distribution (those closer to 10% or 90%) have a smaller margin of error.
