on January 1, 2025 · INE Household Income Distribution Atlas, population in family dwellings on 1 January. Series from January 1, 2016. Up to 2020, INE is missing some municipal values and the municipalities don't add up to the provincial total.

Experimental INE statistic: homes listed on short-term rental platforms. It isn't a licence register and doesn't measure occupancy.

People registered as unemployed

106

Compared with September 2025

+2.9 %

Unemployed job seekers registered with SEPE on the last day of the month. It isn't the EPA unemployment rate, and it isn't divided by population because there is no official municipal denominator.

Affiliates

7,726

Compared with August 2025

+2.1 %

Affiliates on the last day of the month, assigned to the municipality of the employer's contribution account: it counts where people work, not where they live.
