ACS 2020–2024 · Port St. Lucie city, Florida · Incorporated city · GEOID 1258715. The survey estimates a population of 232,491 for its five-year window. This is separate from the annual July 2025 population estimate on the city overview.

Median age in Port St. Lucie is 43.9 years, with a 90% margin of error of 0.6 years. There are 83,952 households (±1,329). Age and household distributions show how these totals are composed; they do not establish which neighborhood suits a particular person.

Every count and share is an estimate. “±” is a 90% margin of error (MOE); pp means percentage points. Derived shares use the category count divided by the named universe. Aggregated category MOEs and percentage MOEs are approximate. A margin larger than half its estimate is flagged as low precision. Blank source uncertainty is shown as unavailable, never zero.
