Roper Center has added a sweet new feature to iPoll.
"You can look at demographic cross-tabulations for over 50,000 questions asked in the US since 2000. The group data is integrated directly into iPOLL and is presented automatically with the question results wherever available. Access to results by gender, age, education, region and more, has never been easier! Just click on the group tab!"
From the iPoll search results screen, look for poll questions with a Question Detail icon that has a green plus sign (see image below).
This indicates you can access the cross-tabs. You will get results like this.
