In eighteen of Mallorca's 53 municipalities, the Spanish-born population declined in 2025. A phenomenon previously unknown in most of these municipalities, the decreases are indicated by figures from the National Statistics Institute which compare municipalities' populations in 2024 and 2025.
The eighteen are: Alcudia, Banyalbufar, Binissalem, Calvia, Campanet, Capdepera, Escorca, Esporles, Estellencs, Felanitx, Llubi, Llucmajor, Palma, Puigpunyent, Sant Llorenç, Selva, Soller and Son Servera. Similar declines have also been registered in Es Castell and Mahon in Menorca and Santa Eularia and Sant Josep de sa Talaia in Ibiza.
The greatest fall, unsurprisingly given the total size of population, was in Palma. There were 1,508 fewer Spanish residents in 2025, while the foreign-born population rose by 6,470. In Calvia, Mallorca's second largest municipality by population, the decrease was 108, while the foreign population increased by 364.
At the other end of the population scale, the three smallest municipalities - Escorca, Estellencs and Banyalbufar - registered decreases of nine, six and four respectively. The foreign population increases were minimal - three, one, two - but were nonetheless representative of this population trend in Mallorca.
For the Balearics as a whole, the Spanish-born population at the end of 2025 was 891,424, an increase of just 275. The foreign-born population meanwhile increased 17,801 to 358,410. In certain Mallorcan municipalities, the foreign population exceeds a Balearic average of just under 30% - Calvia 39%, Alcudia 37%, Santanyi 32%. Only two Mallorcan municipalities showed foreign population decreases in 2025 - Mancor de la Vall and Santa Eugenia.
The explanations for this population trend are pretty obvious - falling Spanish birth rates, some emigration from the islands, and foreign immigration growth that is continuing unabated despite the well-known issues to do with housing. Colombians and Moroccans head the foreign population arrivals followed by Italians and Germans.
INE figures shows that there were 8,835 births in 2025, 2.6% fewer than the previous year, and 9,043 deaths, an increase of 0.5%. The Balearics were the region of Spain where births fell the most, this being attributed at least in part to difficulties faced because of the cost of living.
