Louisa city, KY in context

How this area compares with national benchmarks.

Louisa city is a small town in Kentucky, with 2,645 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #142 of 554 ranked by population — larger than 74% of them. The median age here is 33.8 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 Louisa city earn a median of $41,250 a year, 47.5% below the national figure of $78,538 and 26% below 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 18.8% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Louisa city is valued at $144,900, 52.2% below the national figure and 8% below the $157,200 peer median, while median gross rent runs $444 a month, 68.4% below the national figure, or roughly $5,328 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 3.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 61.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

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.
