Where can I download a blank map of Idaho?
The Idaho 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 Idaho county reference page for county names and identifiers. Do not assume a plain state outline contains county polygons.
How is the Idaho county list organized?
The table lists 44 units alphabetically. For example, its first listed entry is Ada (16001) and its last is Washington (16087). Idaho uses the 16 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, Idaho ranks #32 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 Idaho county maps
How many counties does Idaho have in this reference?
The bundled Idaho table contains 44 names or county-equivalent entries. Use the cited Census vintage before comparing against newer jurisdiction counts.
What is the state FIPS code for Idaho?
The two-digit state FIPS prefix in this dataset is 16. It forms the first two digits of each five-digit county GEOID.
Where can I find the full Idaho county list?
Search the 44-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 Idaho?
Ada appears first in this alphabetized data list with GEOID 16001.
Which county is listed last alphabetically in Idaho?
Washington appears last in the alphabetized reference list, with GEOID 16087.
Can I download a printable blank Idaho map?
Use the Idaho 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 Idaho 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 Idaho?
It combines the 16 state prefix with an individual three-digit county code. For example, Ada uses 16001 in this table.
Does this page show all towns and cities in Idaho?
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 Idaho 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.
