Richfield, ID population, income and ZIP codes

Richfield city is a very small community in Idaho, with 558 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #139 of 236 ranked by population — larger than 41% of them. The median age here is 35.7 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 Richfield city earn a median of $59,375 a year, 24.4% below the national figure of $78,538 and 7% below the $63,864 median for the 100 Idaho cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 20.4% 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 Richfield city is valued at $196,100, 35.4% below the national figure and 28% below the $271,500 peer median, while median gross rent runs $731 a month, 48% below the national figure, or roughly $8,772 across a full year. A household on the local median income would put about 14.8% 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 3.3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 76.3% 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.
