Blackfoot city, ID in context

How this area compares with national benchmarks.

Blackfoot city is a mid-size town in Idaho, with 12,628 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #21 of 236 ranked by population — larger than 91% of them. The median age here is 35.6 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Blackfoot city earn a median of $69,091 a year, 12% below the national figure of $78,538 and 8% above the $63,864 median for the 100 Idaho cities we cover. 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 10.3% of residents here, below the 12.4% national rate.

A household on the local median income would put about 13.9% 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. 72.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners.
