District Maps
Every 10 years, following the decennial census, Ohio General Assembly and Congressional districts are redrawn to reflect changes in the state’s population in two parallel, but separate processes. The goal of each is to preserve the important one person-one vote principle – that all citizens are equally represented at the Statehouse and in the United States Capitol.
These maps were drawn based on data from the 2010 U.S. Census and are in effect from 2012-2022.
The PDF files below contain visual representations of Ohio legislative, judicial and education districts. For more information about what districts you reside in, click here to visit Check My Voter Registration.
