ZIP 59240 in context

How this area compares with national benchmarks.

ZIP 59240 is a very small community in Valley County, Montana, with 26 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #357 of 369 ranked by population — larger than 3% of them. The median age here is 68.4 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 59240 earn a median of not published a year. 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 0% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in ZIP 59240 is valued at $266,700, 12.1% below the national figure, while median gross rent runs not published a month. 100% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 68.4 puts ZIP 59240 well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 26 residents, a handful of survey responses moves every median on this page. Compare ZIP 59240 against its county rather than against national figures.

The Census withheld household income, gross rent for ZIP 59240 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 59240 in context

How 59240 sits inside Valley County and Montana.

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 59240 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Owner-occupied homes are valued at a median of $266,700, 56% above the county figure and close to the statewide ZIP median.

Montana charges 0% statewide, and local governments overlapping 59240 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 59240 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.
