Cubelles is home to approximately 15,000 residents, though the population swells during the summer months as tourists flock to the beaches and local festivals. The town has seen steady growth in recent years, largely due to its appeal as a seaside getaway and its proximity to Barcelona, which makes it a desirable location for commuters looking for a more peaceful living environment.
The population is diverse, with a mix of local Catalonians, Spaniards from other regions, and an increasing number of international residents who have been drawn to the town’s relaxed lifestyle and scenic surroundings. The demographic is also quite family-friendly, making it popular with both young families and retirees.
