Generalists In Florida Population Forecast

If the recent trend holds, Generalists in Florida is projected to fall about 17% by 2030 — from 8.3 in 2025 to a central estimate of 6.9 (95% range 4.3–9.6). A 5-year backtest shows a typical error of ±10.9%, with 100% of held-out values landing inside the 95% band.
