Poll Demographics

About this Poll

The survey of 1,000 registered voters was taken Sept. 30 to Oct. 10 and has a margin of error of 3 percentage points. It found 758 who were classified as likely voters. Few polls of the Illinois contests have sample sizes as large as this one. The margin for error among likely voters is plus or minus 3.5 percentage points. The numbers in this release are those for likely voters.
Results from the entire sample have a statistical margin for error of 3 percentage points at the 95 percent confidence level. This means that if we were to conduct the survey 100 times, in 95 of those instances the results would vary by no more than plus or minus 3 points from the results obtained here. The margin for error will be larger for demographic, geographic and response subgroups.
Likely voters are respondents who passed a two-question "screen": first, that they were absolutely certain to vote, and second, that they knew exactly where their polling place was.
