The comparison of data collected by the Generalitat between 2003 and 2023 reveals that in Alt Pirineu i Aran, the habitual use of Catalan has fallen from 71.7% to just 51.1%, a loss of 20.6 percentage points. This sharp decline is evident across all of Catalonia, particularly affecting social spheres such as conversations among friends, neighbors, or colleagues.
Across Catalonia as a whole, the average habitual use of Catalan has plummeted from 46% in 2003 to the current 32.6%, a loss of nearly one-third.
The regions experiencing the most severe setbacks are Ponent (Plana de Lleida), which lost 25.4 points (dropping from 76.5% to 51.1%), and the Girona regions, which suffered an almost identical drop of 25.3 points, settling at 45%. This places Girona below the halfway mark for habitual Catalan speakers, at levels similar to Camp de Tarragona (37.9%).
The most critical situation is registered in the Barcelona Metropolitan Area (AMB), where the habitual use of Catalan has fallen from 41.5% to 24.7% (-16.8 points), now being the region with the lowest percentage. In the social sphere, use among friends has dropped 15 points (from 61% to 46%), and exclusive use in conversations with friends is now only 15%.
