Four Corners more than doubled from 26,116 residents in the 2010 Census to 56,381 in 2020. The 2024 ACS estimate is higher again, although one-year estimates carry margins of error and should be treated as a current snapshot rather than an exact headcount.
The ACS reports roughly 41,000 housing units but about 32,000 households - a gap of nearly 9,000 units. That gap can include seasonal use, short-term or part-time occupancy, and ordinary vacancy; it should not be interpreted as 9,000 vacation rentals. It does show why access, property management and insurance documentation are recurring inspection issues here.
We do not publish a single Four Corners annual-sales number because the CDP crosses Lake, Orange, Osceola and Polk counties and several postal-city markets. Combining unrelated county or ZIP totals would create a precise-looking but misleading figure.
