San Bartolomé has a population of approximately 18,000 residents, with a diverse mix of locals and expatriates from across Europe. The town has experienced steady growth in recent years, driven in part by its popularity as a tourist destination and the increasing number of people relocating to Lanzarote for its laid-back lifestyle and year-round pleasant climate.
The population is primarily Spanish-speaking, though English and German are also widely spoken, especially in the tourism and service sectors. The town’s demographics reflect a blend of traditional Canarian families and newer residents from mainland Spain and other parts of Europe.
