Sama is a small to mid-sized city, with a population of approximately 10,000 residents. The demographics are a mix of local Asturians and descendants of workers who migrated to the area during the industrial boom of the 19th and 20th centuries. The population is aging, but recent efforts to revitalize the local economy and attract new industries have led to a slight increase in younger residents moving to the area.
While the majority of the population is Spanish, the city has seen some diversity with a small but growing number of international residents, particularly from Latin America and other parts of Europe, adding to its cultural vibrancy.
