Princeton city, KY in context

How this area compares with national benchmarks.

Princeton city is a mid-size town in Kentucky, with 6,242 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #76 of 554 ranked by population — larger than 86% of them. The median age here is 41.2 years against 39.1 nationally, a slightly older 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 Princeton city earn a median of $51,875 a year, 33.9% below the national figure of $78,538 and 6% below the $55,469 median for the 246 Kentucky 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 13.7% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Princeton city is valued at $89,700, 70.4% below the national figure and 43% below the $157,200 peer median, while median gross rent runs $719 a month, 48.9% below the national figure, or roughly $8,628 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 1.7×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 56.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
