Two counties. One honest, side-by-side look

Salt Lake County, with 1,220,916 people in the Census Bureau's July 2025 estimate, more than a third of the state. Utah County is second at 759,859, and it is the one adding people fastest: +15.2% since the 2020 count, against +3.0% for Salt Lake. Davis, Weber, and Washington round out the top five.

By the American Community Survey county median, San Juan and Carbon counties sit lowest, both under a quarter of a million, with Duchesne, Millard, and Uintah close behind. The catch is distance: those are two to four hours from the Wasatch Front, with smaller job markets and fewer services. Among the counties inside a Wasatch Front commute, Weber and Tooele carry the lowest medians. The ranking table above shows every county's figure.

Yes. Every pair of the 20 counties has its own page, 190 in all, and each one runs the same sourced table, the same five deep sections, and a verdict for both sides. The matchup tool at the top of this page takes you straight to any pair. Each county also has a profile page that lists all 19 of its matchups, so a pair is never more than two clicks away.

Yes, though less than people expect. Utah taxes a primary residence on 55 percent of its market value, and the rate is a stack of county, city, school district, and special-service levies certified each year. Two homes of the same value in different counties usually land within a few tenths of a percent of each other, but a city or district with a big bond can push one higher. The pair pages show the effective rate at each county-office town, and the county assessor's site shows the exact rate for any address.

These 20 are every county with more than about 13,000 people, and together they hold nearly the whole state. The other nine, from Emery and Grand down to Daggett, have fewer homes for sale in a year than one Salt Lake County suburb, so a county-level comparison would rest on a handful of sales. Their towns are still covered: Moab, Kanab, Beaver, Panguitch, and Huntington each have a full city guide and a things-to-do list on The Local.

From The Local, the part of this site that covers every one of the 138 towns as a place rather than a listing. Each town has a ranked list, researched and written for that town, and the county pages gather those lists by county so you can see the whole weekend bench in one place. The counts in the tables are the number of ranked lists, not a score.
