  1. Eligible voters are defined as U.S. citizens ages 18 and older. Eligible voters are not the same as registered voters. To cast a vote, in all states except North Dakota, an eligible voter must first register to vote.
  2. The terms “Hispanic” and “Latino” are used interchangeably. References to “whites,” “blacks,” and “Asians” are to the non-Hispanic components of those populations.
  3. This statistical profile of eligible voters in Illinois is based on the Census Bureau’s 2008 American Community Survey (ACS). The ACS is the largest household survey in the United States, with a sample of about 3 million addresses. The data used for this statistical profile come from 2008 ACS Integrated Public Use Microdata Series (IPUMS), representing a 1% sample of the U.S. population. Like any survey, estimates from the ACS are subject to sampling error and (potentially) measurement error. Information on the ACS sampling strategy and associated error is available at An example of measurement error is that citizenship rates for the foreign born are estimated to be overstated in the Decennial Census and other official surveys, such as the ACS (see Jeffrey Passel. “Growing Share of Immigrants Choosing Naturalization,” Pew Hispanic Center, Washington, D.C. (March 28, 2008)).
