How measured: Statistics Portugal trailing-12-month municipality median rent per useful square meter for new lease agreements is multiplied by the midpoint of that municipality's 2021 Census weighted-median useful-area band for two-division and three-division usual-residence dwellings, then converted with the ECB EUR/USD reference rate. This row uses the T1 proxy: two divisions profile and 30 m² - 39 m² weighted-median area band. These are planning profiles, not observed bedroom-specific lease amounts. T1 and T2 are proxied by two and three Census divisions, the rent-per-square-meter source covers all dwelling typologies, and the dwelling-size distribution is from 2021. The published range preserves the full weighted-median area band.

How measured: INE 2025 average actual primary-residence rent among renter households is the rent-exclusive national baseline. It is adjusted by the AEAT 2024 municipality-to-national habitual-rent price-per-square-meter ratio, by the disclosed 50 m2/70 m2 bedroom planning factor, and by the dated ECB EUR/USD reference rate. Model-limited planning profiles, not observed one-bedroom or two-bedroom rents or current asking rents. INE supplies a national actual-rent amount only for households with rent expense; AEAT supplies the municipality price adjustment but not bedroom count. Utilities are separate COICOP categories and are excluded from this rent anchor.
