About the Survey

The results in this report are based on data from telephone interviews conducted by Princeton Survey Research Associates International between August 9 and September 13, 2010, among a sample of 3,001 adults, age 18 and older.  Interviews were conducted in English and Spanish and included 1,000 cell phone interviews.  For results based on the total sample, one can say with 95% confidence that the error attributable to sampling is plus or minus 2.5 percentage points.  For results based on Internet users (n=2,065) and cell phone users (n=2,485), the margin of sampling error is plus or minus 3 percentage points.
