Monthly building permits for residential buildings, measured in number of dwellings, as a seasonally and calendar adjusted index (2021=100). Eurostat dataset sts_cobp_m ('Building permits by type of building - monthly data'), indicator indic_bt=BPRM_DW (building permits, number of dwellings), building type cpa2_1=CPA_F41001_X_410014 ('Residential buildings, except residences for communities' - the dwellings headline total; residences for communities are excluded by construction), s_adj=SCA (seasonally and calendar adjusted), unit I21 (index, 2021=100). Each row is one (month, country). Method: short-term business statistics compiled by Eurostat from national statistical institutes' building-permit registers; the SCA series removes seasonal and calendar effects. Units: index points (2021=100). Caveats: permits are authorizations, not starts or completions; national series start dates vary and some countries revise late data; the UK is dropped by the connector's commercial-use geo rule; the EU27_2020 and EA aggregates are included as published. Coverage: ~20 geographic units after the geo rule, monthly from the early 2000s (varies by country) to the latest month. Provenance: Eurostat keyless JSON-stat API, free reuse with attribution (Commission Decision 2011/833/EU) - please cite Eurostat. Primary key: (month, country_code). Join keys: country_code (ISO 3166-1 alpha-3), month. Cadence: refreshed monthly; Eurostat publishes the series about two months after the reference month. Sample use: filter country_code='DEU' to track German residential construction authorizations.
Monthly building permits for residential buildings, measured in square metres of useful floor area, as a seasonally and calendar adjusted index (2021=100). Eurostat dataset sts_cobp_m ('Building permits by type of building - monthly data'), indicator indic_bt=BPRM_SQM (building permits, m2 of useful floor area), building type cpa2_1=CPA_F41001_X_410014 ('Residential buildings, except residences for communities' - the headline residential total), s_adj=SCA (seasonally and calendar adjusted), unit I21 (index, 2021=100).

Join keys: country_code (ISO 3166-1 alpha-3), month. Cadence: refreshed monthly; Eurostat publishes the series about two months after the reference month. Sample use: compare with 'eurostat-building-permits-dwellings-monthly' (dwellings vs floor area) to see whether new homes are getting bigger or smaller.
Housing Market Signals (derived)
Signals derived from FRED's US housing series: 30-period annualized volatility of changes, 3-month momentum, year-over-year percent change (the Case-Shiller boom/bust gauge), 3-sigma anomaly flags, naive-drift 1-month forecasts, a per-date cross-series volatility rank, and the permits-to-starts pipeline ratio. Covers HOUST (monthly housing starts), PERMIT (monthly building permits), CSUSHPISA (S&P/Case-Shiller U.S. National Home Price Index), MORTGAGE30US (weekly 30-yr fixed mortgage rate) and HSN1F (monthly new one-family houses sold). All rows are normalized to country_code USA so they join cleanly with US macro data. Raw series: Federal Reserve Bank of St. Louis (FRED).
