US state housing-momentum signals (FHFA HPI boom/bust gauges)
Quarterly housing-momentum signals derived from FHFA All-Transactions House Price Indexes (FRED, 50 states + DC + US national, 1975 ->): quarter-on-quarter and year-on-year price changes, 30-quarter change volatility, 3-sigma anomaly flags vs a trailing-12-quarter baseline, drift forecasts, per-quarter cross-state volatility ranks, state-vs-nation divergence gaps, 10-year house-price z-scores, cycle-position percentiles, and boom/cooldown flags. The state-breadth companion to the national housing signals. Country codes normalized to ISO alpha-3 (USA). Raw data: Federal Housing Finance Agency via FRED.
