FairVote2020 has developed an interactive map showing voter registration rates in Ohio communities and neighborhoods as of the summer of 2003. Boundaries for the thematic display are based on census block groups rather than precinct lines because there is no publicly available statewide geographic precinct database -- current or historical.
Zooming in to a scale of about five miles, you will see the estimated number of unregistered persons (by block group) displayed in purple boxes.
You can view socioeconomic themes -- race, ethnicity, income, access to vehicles, etc. -- for these neighborhood areas by selecting maps from the drop-down menu under "Compare Maps" on the left. These maps also show block group-level detail, providing an exact boundary match to the voter registration data.
Below the links to the interactive maps is a link to a directory with nearly 1,500 maps in Adobe format -- printer-ready and PDA compatible. These maps show street-level detail for areas in 57 counties with high numbers of unregistered or inactive voters. Over 700,000 unregistered or inactive voters live in these areas -- defined by populations that are 30% or more below poverty or 30% or more minority voting age.
There is also a link to Adobe maps showing neighborhood registration rates for 115 Ohio localities with populations greater than 15,000.

Map 1 (default map) -- Unregistered or Inactive Voting Age Population in 2003
At a scale of about 5 miles, the estimated number of voting age persons (by block group) who are unregistered or inactive is displayed in purple boxes. When you click on ZOOM TO and then click on the map -- voter registration and demographic data for the block group selected will appear in a table below the map. Click on INFO and then click on the map for more detailed data.
At a scale of about 3 miles, green labels showing the block group numbers can be displayed by checking the box next to "BG FIPS code" below the map image. (The five digit state-county portion of the number, e.g. "39003" is not shown in the map -- 39 is for Ohio and 003 indicates Allen County -- but is displayed using the INFO button and must be entered for searches based on the block group code using FIND. )
This map is based on a June 2003 statewide registered voter file with 7.3 million names. Approximately 98% of the addresses are geocoded. For the map theme, we eliminated from the registered count anyone who had not voted for the previous six years. This reduces the statewide registered voter count to 5.3 million persons -- roughly in line with Census Bureau survey estimates of 5.56 million registered in 2000 (see link below). The census survey reports that 4. 82 million persons voted in 2000.
Blank areas on the map depict areas where the geocoding or voter data was faulty.

Map 18 Statewide Focus Areas
See also Adobe maps below. This map displays neighborhoods and communities with 30% minority voting age population or 30% or more persons below poverty and an estimated 200 or more unregistered or inactive voters. Statewide there are about 1,450 block groups falling into one or both categories.
Street-level printer-ready, PDA compatible detail maps can be downloaded by clicking on the INFO button and then on the precinct of interest. Next select "Focus Areas" and select the Adobe map link from the lower half of the pop-up window. Right click and select Save Target As or Open in New Window).
Batch downloads for the Adobe files organized by county, zip code, city, and block group can be accessed via this directory:

These street-level maps show neighborhoods and communities with populations that are 30% or more minority or 30% or more below poverty, according to the 2000 census, with at least 200 or more estimated unregistered or inactive voters. Over 700,000 unregistered or inactive voters reside in these areas, representing nearly two-thirds of the resident 1.2 million persons of voting age in the focus areas. There are focus areas in 57 of the state's 88 counties.
White numbers overlaying dots show estimated unregistered or inactive voters by census block. These dots are color-coded to show race/ethnicity components for the over 18 population residing in the census block.
The files are organized by county, zip code, city, and block group number.

Birds-eye view of neighborhood-level registration rates. These maps can be used for orientation purposes with the "focus area" block-level maps above. The numbers displayed in purple boxes show unregistered or inactive voters and will match the unregistered voter count in the footer portion of the block-level "focus area" maps.
