ZIP code 33131

ZIP 33131 is a mid-size town in Miami-Dade County, Florida, with 23,289 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #422 of 1,013 ranked by population — larger than 58% of them. The median age here is 36.3 years against 39.1 nationally, a slightly younger 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 ZIP 33131 earn a median of $143,114 a year, 82.2% above the national figure of $78,538. 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. Poverty reaches 6.1% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in ZIP 33131 is valued at $621,700, 104.9% above the national figure, while median gross rent runs $2,847 a month, 102.5% above the national figure, or roughly $34,164 across a full year. A household on the local median income would put about 23.9% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 4.3×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 35.5% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.

ZIP 33131 is tabulated inside Miami-Dade County, Florida, one of 80 ZIP areas the Census publishes for that county and 1,013 across Florida. This is a mid-sized suburban ZIP inside a county that is split across many delivery areas. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 33131 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 33131 reports a median household income of $143,114, 97% above the $72,564 county median, and 105% above the $69,820 typical FL ZIP. Owner-occupied homes are valued at a median of $621,700, 47% above the county figure and 110% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $2,847 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

A taxable purchase made inside 33131 carries 7% at the register, assembled from the Miami jurisdiction stack: the Florida state rate plus every county, municipal and special district levy that reaches this address. Because those district boundaries were drawn for schools, transit and hospital funding rather than for mail delivery, two addresses inside 33131 can legitimately fall under different totals — the rate shown here is the one that applies to the dominant jurisdiction.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 33131 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
