Lewis and Clark ZIP codes — Lewis and Clark County, Montana

Lewis and Clark County is a small city in Montana, with 72,580 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 41.3 years against 39.1 nationally, a slightly older profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Lewis and Clark County earn a median of $74,543 a year, 5.1% below the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 8.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Lewis and Clark County is valued at $358,200, 18.1% above the national figure, while median gross rent runs $1,062 a month, 24.5% below the national figure, or roughly $12,744 across a full year. A household on the local median income would put about 17.1% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 4.8×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 69.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
