KNOW YOUR GEOGRAPHY

Columbus, Lake Erie and the Ohio River.

The county map follows Ohio from the Lake Erie shore to the river border in the south. Franklin, Delaware, Madison and Union are separate county features, so you can compare the Columbus area without assigning it one fill.

Values attached to Cleveland, Cincinnati or another municipality need to be checked for geographic coverage. Join data at county scale when it describes Cuyahoga, Hamilton or another entire county.

Delaware and Meigs bracket the income estimates.

Delaware had the highest county median household income estimate at $133,540, and Meigs had the lowest at $46,873. The sequential classes show how estimates vary across the state without implying that all households inside a county earn similar amounts.

COMMON QUESTIONS

Ohio county map questions.

Can I compare Franklin and Delaware separately?

Yes. Franklin is 39049 and Delaware is 39041. Their separate features let you test how a central Ohio pattern looks at county scale.

Does the Lake Erie outline include islands?

The map shows the islands retained by the existing 2025 Census cartographic boundaries. Where a county has multiple pieces, those pieces share one county identifier.

Which county GEOID should I use for Cleveland area data?

Use 39035 when the observation covers Cuyahoga County. City of Cleveland data requires checking its coverage before joining it to a county feature.

Why do the growth and domestic migration maps differ near Columbus?

The population map includes total change, while domestic migration counts net moves within the United States. Franklin had positive total change and negative net domestic migration.

What does a darker income shade in Delaware mean?

It identifies the class of the county’s estimated median household income in 2024 dollars. It does not show individual salaries or the cost of living.

Can I show counties on both sides of the Ohio River?

Use the national county editor to combine Ohio with counties in Kentucky or West Virginia. State and county digits together identify the correct records.
