Abstract
The rationalization of the Spanish municipal map has been a recurring issue in recent times. In times of economic crisis, there have been numerous voices calling for rethinking and modernizing the municipal and provincial level, which has remained practically unchanged since its establishment in 1833. However, apart from some legislative changes that tried to stimulate the merger of municipalities and some controversial recent experience, the number of municipalities has continued to grow to its current 8,132.
The latest to join the list, at the end of 2023, was Usansolo with its population of only 4,500 and priorly a neighborhood of Galdácano (Galdakao in Basque).
