✅Oklahoma County Map
Counties are the main sub state units used for records, mapping, and many everyday tasks. This page keeps the focus on all 29 Utah counties first, then adds a few compact notes that help people use county level data well.
Why counties matter
- Addresses and services often key off county boundaries.
- Public records (property, courts, permits) are commonly organized by county.
- Data work uses county FIPS codes to join datasets cleanly.
Quick definitions
County seat is the administrative hub for county services.
FIPS code is a standard numeric ID used in many United States datasets.
Area helps compare scale, while density helps compare how concentrated people are.

Population values below use the 2020 Census as a stable baseline. Density is a simple population divided by land area calculation, useful for quick comparisons.

How to use Utah county data without getting tripped up
FIPS codes for clean joins
- Utah state code is 49, then the 3 digit county code.
- Example: 49049 always means Utah County.
- FIPS is steady even when county population changes.
County seat is not always the biggest city
County seats are where many official offices cluster. In everyday life, the largest city can be elsewhere in the same county. It happens across teh state.
- Use the seat when you need county administration.
- Use the county name when matching datasets or filtering maps.
Fast checks that save time
- Same name, different thing: Utah can mean the state, and Utah County is a county inside the state.
- Area vs population: large area does not mean more people. San Juan County is huge by area, while Salt Lake County leads by population.
- Density tells a different story: Davis County is small in area, yet very dense.
Utah counties by practical region a simple way to think about geography
These groupings are not official. They are a tidy mental model for planning, analysis, and search filters.
Wasatch Front core high density
- Davis (very dense)
- Salt Lake (largest population)
- Utah (second largest population)
- Weber (major urban corridor)
North and mountain counties mix of valleys and peaks
- Box Elder, Cache, Rich
- Morgan, Summit, Wasatch
- Daggett is also in the far northeast corner.
Central Utah wide open, smaller cities
- Juab, Millard, Sanpete
- Sevier, Piute
East and south big landscapes
- Uintah, Duchesne, Carbon, Emery, Grand
- Beaver, Iron, Washington, Kane, Garfield, Wayne, San Juan
Quick stats that people look up a lot
