Fall Tracking Survey
This report is based on the findings of a daily tracking survey on Americans’ use of the internet. Unless otherwise noted, the results in this report are based on data from telephone interviews conducted by Princeton Survey Research International between August 18 to September 14, 2009, among a sample of 2,253 adults, 18 and older. The survey was conducted on landline and cell phones. Interviews were conducted in both English (n=2,179) and Spanish (n=74). For results based on the total sample, one can say with 95% confidence that the error attributable to sampling and other random effects is plus or minus 2.3 percentage points. For results based on internet users (n=1,698), the margin of sampling error is plus or minus 2.7 percentage points. In addition to sampling error, question wording and practical difficulties in conducting telephone surveys may introduce some error or bias into the findings of opinion polls. The response rate to the survey was 15.6%.
