Seasonal population estimates. Municipalities with more AFTE seasonal population

AFTE seasonal population

The result of the balance between entries of population not resident in the municipality and exits of population resident in the municipality, measured as an annual average number of people per day (annual full time equivalents).

AFTE population

Population resident in a municipality, measured as the annual average of people per day (annual full time equivalents). It is the equivalent to the sum of the resident population and the entries of non resident population in the municipality minus the exits of the population resident in the municipality.

Resident population

Registered population in the municipality.

The Seasonal population estimates constitute an estimation of the population burdens supported by each municipality and measure the number of people there are in a municipality as a yearly average and a quarterly average. The calculation includes people that have some sort of association or relation with the municipality, whether that is because they reside there, work there, study there or despite not having their regular residence there, spend some period of time there (holidays, summer breaks, weekends, etc.), either in their own homes or in those of friends and family or in tourist establishments (hotels, campsites, apartments, habitatges d'ús turístic, etc.). S'han considerat els moviments sense pernoctació per raó de treball i estudis, i en la base 2021 també per turisme. En canvi, no s'han considerat els moviments sense pernoctació per altres motius (per exemple, lleure, compres o visites mèdiques).

The measurement unit for seasonal population estimates are annual full time equivalents. Every day that a person is present in a municipality equates to 1/365 annual full time equivalents (AFTE). So, for example, a person who spends a week's holiday in a municipality equates to 0.02 AFTE.

The conceptual framework for the seasonal population estimates includes four variables. On the one hand, the AFTE population and the seasonal AFTE population measure the resident population along with flows in and out of the municipality. On the other, the AFTE resident plus visitor population and the resident plus visitor population measure the resident population and only the flows into the municipality.

In 2022, Idescat improved the estimate of the seasonal population. The territorial disaggregation was expanded to offer results for all municipalities with 1,000 inhabitants and over (either registered or AFTE population). An estimate of overnight stays in tourist accommodations and an estimate of hikers for tourist purposes have been added. A new base 2021 has been established to collect these methodological changes.
