Recent data from Idescat indicates that the number of people who changed municipalities in Catalonia during 2024 reached 282,739, exceeding by 8,597 the movements recorded in the preceding year. These internal transfers primarily occurred between different counties, accounting for more than half of the total.
A notable aspect of this demographic dynamic is the profile of the individuals who relocated: almost one third of them were foreign nationals. This data highlights the relevance of immigration in the region's internal mobility patterns.
Regarding the internal migratory balance, which measures the difference between population arrivals and departures to or from other Catalan municipalities, several localities recorded positive figures. Terrassa led the list with a balance of 1,470 people, followed by Vilanova i la Geltrú (691), Badalona (601), Sabadell (554), Cunit (452), and Sant Joan Despí (412).
In contrast, major cities such as Barcelona experienced the most negative internal migratory balances, with a loss of 15,221 residents. Other municipalities with significant negative balances included l'Hospitalet (-1,759), Sant Cugat (-824), and Tarragona (-568).
