Parish geography of 2025 (CAOP2025). Nationality (Portuguese, foreign, stateless) is INE indicator 0014632. * Indicator published by INE only for 2013 parish geography (NUTS 2024); used because the parish has the same territory in both geographies (identical population by sex and age group). Ageing index = population aged 65+ ÷ population aged 0–14 × 100; share with higher education = residents with completed higher education ÷ residents aged 15 or over (our calculations from INE figures).
