Where can I download a blank map of Ohio?
The Ohio blank map download page offers the currently bundled printable formats and map styling controls. Check the selected variant before using it for county-level teaching: an outer-state outline does not necessarily contain individual county borders, county seats, or city boundaries.
Use the Ohio county reference page for county names and identifiers. Do not assume a plain state outline contains county polygons.
How is the Ohio county list organized?
The table lists 88 units alphabetically. For example, its first listed entry is Adams (39001) and its last is Wyandot (39175). Ohio uses the 39 prefix in this reference dataset. Any count should be compared only against a consistent state, county-equivalent, and data-vintage definition.
How does the county count compare with other states?
In the bundled 51-jurisdiction list, Ohio ranks #13 by listed county-equivalent count. A rank based on a historical list is not a claim about current US Census legal definitions.
Frequently asked questions about Ohio county maps
How many counties does Ohio have in this reference?
The bundled Ohio table contains 88 names or county-equivalent entries. Use the cited Census vintage before comparing against newer jurisdiction counts.
What is the state FIPS code for Ohio?
The two-digit state FIPS prefix in this dataset is 39. It forms the first two digits of each five-digit county GEOID.
Where can I find the full Ohio county list?
Search the 88-row county/GEOID table on this page. It includes the names and five-digit identifiers available in the bundled dataset.
Which county is listed first alphabetically in Ohio?
Adams appears first in this alphabetized data list with GEOID 39001.
Which county is listed last alphabetically in Ohio?
Wyandot appears last in the alphabetized reference list, with GEOID 39175.
Can I download a printable blank Ohio map?
Use the Ohio blank-map page linked above and select the available SVG, PNG or PDF export. Examine the map variant before assuming it contains internal borders.
Does this Ohio table contain county populations?
No. This bundled names/GEOID table does not include dated population figures. Download a comparable Census vintage for trustworthy counts.
What is a five-digit GEOID in Ohio?
It combines the 39 state prefix with an individual three-digit county code. For example, Adams uses 39001 in this table.
Does this page show all towns and cities in Ohio?
No. It lists county names and identifiers, not every incorporated city, municipality or settlement. A separately licensed place dataset is needed for city coverage.
Are Ohio county boundaries official and current here?
No. The county names and identifiers are from a bundled reference with an unverified vintage. For authoritative current boundary shapes, consult the US Census Bureau TIGER/Line or cartographic boundary releases.
Data sources, definitions and update notes
County names and identifiers are taken from a bundled historical reference dataset whose exact release year has not been independently established. For current official data, use US Census Gazetteer Files and TIGER/Line. Connecticut planning regions, Alaska borough/census areas, Louisiana parishes, independent cities and DC can require different definitions. No unverifiable population, capital, median income, adjacent county or legal-border claim is made here.
