Louisville/Jefferson County metro government (balance) is a major city in Kentucky, with 627,210 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it first of 554 ranked by population. The median age here is 37.7 years against 39.1 nationally, a slightly younger profile than the country as a whole.

The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean.

The typical owner-occupied home in Louisville/Jefferson County metro government (balance) is valued at $221,500, 27% below the national figure and 41% above the $157,200 peer median, while median gross rent runs $1,069 a month, 24% below the national figure, or roughly $12,828 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 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 60.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
