Valencia (EFE) 2019.
Based on the official data from the latest census published by the National Institute of Statistics (INE), corresponding to 2022, and the electoral legislation, which sets the number of mayors by population scale, there are 21 municipalities with more than 20,000 inhabitants that increase their number of councilors, and 2 that reduce them.
others go down
The two towns that will see their municipal corporation reduced in the elections on May 28 are Barañáin (Navarra) and Calatayud (Zaragoza), since they have dropped below 20,000 inhabitants, which means going from 21 to 17 councilors and therefore losing four.
Of the 418 Spanish municipalities with more than 20,000 inhabitants, the largest whose number of mayors varies is Roquetas de Mar (Almería), which, having exceeded one hundred thousand residents, gains two mayors and will go from 25 to 27.
Having exceeded 50,000 inhabitants will allow six towns to have four more councilors and go from 21 to 25: Rincón de la Victoria (Málaga), Granadilla de Abona (Santa Cruz de Tenerife), Ibiza and Calvià (Balearic Islands) and Colmenar Viejo y Tres Songs (Madrid).
Likewise, there are fourteen towns that have exceeded 20,000 inhabitants in the last census, which implies having 4 more councilors (they go from 17 to 21). This is the case of Huércal-Overa (Almería), Sant Quirze del Vallés and Les Franqueses del Vallés (Barcelona), Banyoles (Girona) and Puçol (Valencia).
Burlada (Navarra), Mogán (Las Palmas), O Porriño (Pontevedra), Alcúdia (Baleares), Cartaya (Huelva), Güímar and San Miguel de Abona (Santa Cruz de Tenerife), Arroyo de la Encomienda (Valladolid) and La Unión (Murcia) complete this list.
