The majority of the population is of Spanish descent, though in recent years, the city has seen modest growth in immigrant populations, particularly from Latin America and Eastern Europe. This has added a layer of diversity to the local community, while traditional Castilian customs remain dominant in daily life.
The population is relatively balanced across age groups, with a mix of young families, working professionals, and retirees. The city has a warm, welcoming atmosphere, with strong community ties and a focus on preserving local traditions.
