San Celoni has a population of approximately 18,000 residents. The town is predominantly Catalan-speaking, though Spanish is also widely spoken, reflecting the region’s bilingual nature. The population is a mix of young families, older residents, and a growing number of expats who are drawn to the area for its quality of life, beautiful surroundings, and proximity to Barcelona.
In recent years, San Celoni has experienced moderate population growth, partly due to its appeal as a commuter town for those working in Barcelona but seeking a quieter, more affordable place to live. The town has a strong sense of community, with many local events and initiatives designed to bring residents together.
