Mammoth, WY population, income and ZIP codes

Mammoth CDP is a very small community in Wyoming, with 50 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #170 of 205 ranked by population — larger than 17% of them. The median age here is 76.2 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 Mammoth CDP earn a median of not published a year. 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 26% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Mammoth CDP is valued at not published, while median gross rent runs not published a month. 0% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. 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 76.2 puts Mammoth CDP 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 50 residents, a handful of survey responses moves every median on this page. Compare Mammoth CDP against its county rather than against national figures.

The Census withheld household income, home value, gross rent for Mammoth 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.
