Brentwood, TN population, income and ZIP codes

Brentwood city is a small city in Tennessee, with 45,272 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #18 of 504 ranked by population — larger than 96% of them. The median age here is 44 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 Brentwood city earn a median of $184,720 a year, 135.2% above the national figure of $78,538 and 230% above the $55,988 median for the 307 Tennessee cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 2.5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Brentwood city is valued at $926,700, 205.4% above the national figure and 385% above the $191,100 peer median, while median gross rent runs $2,497 a month, 77.6% above the national figure, or roughly $29,964 across a full year. A household on the local median income would put about 16.2% 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 5×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 90.9% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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.
