Port St. Lucie, FL population, income and ZIP codes

Port St. Lucie city is a mid-size city in Florida, with 220,453 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #7 of 955 ranked by population — larger than 99% of them. The median age here is 43.7 years against 39.1 nationally, a slightly older profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Port St. Lucie city earn a median of $78,137 a year, essentially level with the national figure of $78,538 and 14% above the $68,617 median for the 775 Florida 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 8.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Port St. Lucie city is valued at $327,700, 8% above the national figure and 7% above the $305,300 peer median, while median gross rent runs $1,781 a month, 26.7% above the national figure, or roughly $21,372 across a full year. A household on the local median income would put about 27.4% 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 4.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 83.2% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
