Jefferson City, MT population, income and ZIP codes

Jefferson City CDP is a very small community in Montana, with 446 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #164 of 497 ranked by population — larger than 67% of them. The median age here is 38.8 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 Jefferson City CDP earn a median of $73,875 a year, 5.9% below the national figure of $78,538 and 17% above the $62,992 median for the 94 Montana cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 4.9% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Jefferson City CDP is valued at $282,000, 7.1% below the national figure and 12% above the $250,900 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 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.

With 446 residents, a handful of survey responses moves every median on this page. Compare Jefferson City CDP against its county rather than against national figures.

The Census withheld gross rent for Jefferson City CDP 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.
