Sidney city, MT in context
How this area compares with national benchmarks.
Sidney city is a mid-size town in Montana, with 6,235 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #19 of 497 ranked by population — larger than 96% of them. The median age here is 38.9 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.
Households in Sidney city earn a median of $62,992 a year, 19.8% below the national figure of $78,538 and within a couple of points of the $62,992 median for the 94 Montana cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 8.6% of residents here, below the 12.4% national rate.
The typical owner-occupied home in Sidney city is valued at $249,100, 17.9% below the national figure and within a couple of points of the $250,900 peer median, while median gross rent runs $890 a month, 36.7% below the national figure, or roughly $10,680 across a full year. A household on the local median income would put about 17% 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×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 61.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.
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.
