ZIP 59318 in context

How this area compares with national benchmarks.

ZIP 59318 is a very small community in Garfield County, Montana, with 145 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #294 of 369 ranked by population — larger than 20% of them. The median age here is 35.5 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in ZIP 59318 earn a median of $70,000 a year, 10.9% below the national figure of $78,538. 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 11% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 59318 is valued at $206,700, 31.9% below the national figure, while median gross rent runs not published a month. The home-price-to-income ratio works out to 3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 78.3% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

With 145 residents, a handful of survey responses moves every median on this page. Compare ZIP 59318 against its county rather than against national figures.

The Census withheld gross rent for ZIP 59318 because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.

Reading ZIP 59318 in context

How 59318 sits inside Garfield County and Montana.

ZIP 59318 is tabulated inside Garfield County, Montana, one of 6 ZIP areas the Census publishes for that county and 369 across Montana. This is one of the smallest tabulated ZIP areas in the state, the kind of rural route where a single subdivision or farm cluster accounts for most addresses. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 59318 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 59318 reports a median household income of $70,000, 3% above the $67,917 county median, and 9% above the $64,375 typical MT ZIP. Owner-occupied homes are valued at a median of $206,700, 8% below the county figure and 23% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at not published a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Montana charges 0% statewide, and local governments overlapping 59318 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 59318 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
