Ohio 2020 Census Voting District Boundaries

2020 Census data provides Voting District (VTD) boundaries for the state of Ohio. The dataset is an extract from the Census Bureau's MAF/TIGER Database, designed as a seamless national file. It includes VTDs established by state governments for conducting elections, identified by unique alphanumeric codes within each county.

Use Cases

• Analyze the spatial distribution and boundaries of Voting Districts (VTDs) for electoral planning in Ohio.
• Map precincts, wards, and election districts using the unique 1- to 6-character alphanumeric census codes assigned to each VTD.
• Identify county areas without defined VTDs by filtering for the designated 'ZZZZZZ' census code.
• Combine this Ohio VTD shapefile with other state files from the TIGER/Line series to create a national map of voting districts.

Strengths

• Data originates from the authoritative U.S. Census Bureau MAF/TIGER Database, ensuring national consistency.
• Boundaries are part of the 2020 redistricting program under Public Law 94-171, providing official state-submitted data.
• The TIGER/Line shapefile format is designed to stand alone or be combined seamlessly with other files for national coverage.

Limitations

• Voting districts do not exist for all states; this dataset is specific to Ohio's participation in the 2020 program.
• The 'ZZZZZZ' code indicates portions of counties where no VTDs were identified, representing gaps in coverage.
• As a 2020 Census product, boundaries may not reflect subsequent local redistricting or annexation changes.
