Building permits: useful floor area (monthly, Europe)

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). 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.

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.
