Notes:
- Results have been conveniently rounded and displayed without decimals. Hence, some totals may not coincide with the sum of their disaggregation by age or territory.
- The population of Catalonia in the Municipal Population Projections differs from that published in the County Population Projections because the starting population is different (the former uses the Population Register and the latter Population Estimates).
- The municipalities are classified by sections of population according to its size in 2021.

Methodological note

Methodological aspects

The goal of population projections is to describe possible future population evolution, both in total size and according to different variables: sex and age; place of residence; composition of the household; relationship with the activity.

Municipal population projections are drawn up using the componential method with a multi-regional focus. This method consists in adding the demographic growth components to the baseline pyramid each year: the natural growth flows (births and deaths) and the migration flows (immigration and emigration). At the same time, this ensures the consistency both between the results for counties and municipalities and among the municipalities of the same county.

The reference date for projected populations is 1 January each year.

The municipal population projections (base 2018) consist of two scenarios; the average scenario and the standard scenario. The two scenarios incorporate the same assumptions about the future evolution of fertility, mortality and migrations (immigration and emigration), but differ in the baseline population.

In the municipal population register scenario, the baseline pyramid is the population as per the Municipal Population Register as of 1 January 2018, with a correction in some municipalities of 0 years based on the births figure.
