New Plymouth city, ID in context
How this area compares with national benchmarks.
New Plymouth city is a small town in Idaho, with 1,863 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #70 of 236 ranked by population — larger than 70% of them. The median age here is 32.4 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 New Plymouth city earn a median of $59,875 a year, 23.8% below the national figure of $78,538 and 6% 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 9% of residents here, below the 12.4% national rate.
The typical owner-occupied home in New Plymouth city is valued at $199,200, 34.3% below the national figure and 27% below the $271,500 peer median, while median gross rent runs $988 a month, 29.7% below the national figure, or roughly $11,856 across a full year. A household on the local median income would put about 19.8% 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. 69% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.
No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
