KNOW YOUR GEOGRAPHY

County outlines across western mountains and eastern plains

The editor follows Montana’s county boundaries along the western mountains and across the eastern plains. Gallatin contains Bozeman and Yellowstone contains Billings. A larger shape on the map does not imply a larger population.

Tribal lands and reservation boundaries are separate geographic layers. This county map represents Census county identities.

OFFICIAL DATA

Residents added and percentage growth tell different stories

Yellowstone added more residents than Richland, but Richland had the larger percentage gain. Look at the starting population alongside the mapped rate.

July 2024 to July 2025 · 56 counties

Richland and Flathead both recorded net domestic gains

Richland had +23.08 net domestic movers per 1,000 residents, Flathead +7.95, and Lewis and Clark +3.52. A small population makes a rate sensitive to a relatively modest number of movers.

COMMON QUESTIONS

Montana county map questions.

Is Bozeman a selectable area in this editor?

Bozeman is in Gallatin County. Use GEOID 30031 for the county fill.

Which county contains Billings?

Billings is in Yellowstone County, GEOID 30111.

Can I use reservation-level data directly in this county map?

Use a Tribal geography layer for reservation-level data. Tribal boundaries and county boundaries define different reporting areas.

Why can a small Montana county have a high growth rate?

A modest change becomes a larger percentage when the starting population is small. Compare counts and rates together.

How do I join Lewis and Clark County in a CSV?

Use 30049. The GEOID avoids ambiguity over punctuation and spacing in a name column.

What does domestic migration count here?

The rate measures net moves within the United States relative to county population. It excludes international migration and does not capture total population change.
