Why Do We Poll?

Check out the latest Spring 2018 the Simon Poll™ Press Releases

The Simon Poll™ is an annual statewide poll asking Illinois voters’ opinions on important current public policy topics, typically with a focus on state budget issues, political and electoral reform, politics, and social issues.  The Southern Illinois Poll™ collects voter opinion in the southernmost 18 counties in Illinois.

The Simon Poll™ of registered voters in Illinois has been conducted since 2008 and the Southern Illinois Poll™ has been conducted since 2010.  In addition to helping chart public opinion for policy makers, graduate students also use the polling to include questions useful to them in their papers, dissertations and research projects.

A range of public policy issues are present in the collection. Issues include primary and general elections, potential political reforms, political polarization, immigration, elected officials’ approval ratings, public disclosure and corruption, Illinois budget and pensions, guns and society, and social issues, such as abortion, marriage rights, and medical marijuana. Standard demographic data are also included.

For Students

Every year the Institute’s statewide Simon Poll interviews 1,000 registered voters statewide, including questions on electoral politics, public policy, and political reform. We also conduct occasional polls of Southern Illinois residents in the southernmost 18 counties of Illinois on local and political issues.

We have included questions from SIU graduate or undergraduate students in most of our polls, which has helped to provide them data for research projects, master’s theses and doctoral dissertations.

The Simon Poll and Southern Illinois Poll have so far helped students in political science, sociology, geography, and journalism, but the opportunity is open to students in any discipline that includes public opinion in its areas of study.
