Ferrol has a population of approximately 65,000 people, with a demographic makeup typical of many medium-sized Spanish cities. The population is predominantly Spanish, with a significant portion of residents identifying as Galician, reflecting the strong regional identity of Galicia. The city also has a small but growing population of immigrants, primarily from Latin America, Africa, and other parts of Europe, contributing to its cultural diversity.
Like many cities in Galicia, Ferrol has seen a decline in population over recent decades, largely due to economic migration to larger cities in Spain and abroad. However, the city is working on revitalization efforts to attract new residents, including young professionals and families looking for a quieter lifestyle with access to beautiful natural surroundings.
