Mount Plymouth, FL population, income and ZIP codes

Mount Plymouth CDP is a small town in Florida, with 4,688 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #498 of 955 ranked by population — larger than 47% of them. The median age here is 37.6 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 Mount Plymouth CDP earn a median of $88,112 a year, 12.2% above the national figure of $78,538 and 28% above the $68,617 median for the 775 Florida cities we cover. 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 9.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Mount Plymouth CDP is valued at $303,600, essentially level with the national figure and within a couple of points of the $305,300 peer median, while median gross rent runs $932 a month, 33.7% below the national figure, or roughly $11,184 across a full year. A household on the local median income would put about 12.7% 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. 88.2% 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
