Northfield, KY population, income and ZIP codes

Northfield city is a small town in Kentucky, with 1,104 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #233 of 554 ranked by population — larger than 58% of them. The median age here is 51.7 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 Northfield city earn a median of $110,714 a year, 41% above the national figure of $78,538 and 100% above the $55,469 median for the 246 Kentucky 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 5.4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Northfield city is valued at $485,800, 60.1% above the national figure and 209% above the $157,200 peer median, while median gross rent runs $1,533 a month, 9% above the national figure, or roughly $18,396 across a full year. A household on the local median income would put about 16.6% 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 4.4×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 67.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 51.7 puts Northfield city 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.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
