Terrassa has a population of approximately 225,000 residents, making it one of the largest cities in Catalonia. The city has seen steady population growth in recent years, partly due to its proximity to Barcelona and its appeal as a residential area for professionals and families seeking a quieter but still well-connected environment.
The city’s population is diverse, with a mix of Catalans and people from other regions of Spain, as well as international residents. This diversity is reflected in the city’s cultural scene, with festivals and events celebrating both local Catalan traditions and broader multicultural influences.
