Williamstown city, KY in context
How this area compares with national benchmarks.
Williamstown city is a small town in Kentucky, with 3,929 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #103 of 554 ranked by population — larger than 81% of them. The median age here is 33.9 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 Williamstown city earn a median of $71,761 a year, 8.6% below the national figure of $78,538 and 29% above 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.

The typical owner-occupied home in Williamstown city is valued at $159,100, 47.6% below the national figure and within a couple of points of the $157,200 peer median, while median gross rent runs $770 a month, 45.2% below the national figure, or roughly $9,240 across a full year. A household on the local median income would put about 12.9% 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 2.2×, 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. 70.1% 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.
