Marchena has a population of approximately 20,000 residents, most of whom are of Spanish descent, with deep roots in the region. The town maintains a close-knit community atmosphere, where local traditions and family values are highly respected. Despite its relatively small size, the town’s population has been stable, with slight growth due to its appeal as a quieter, yet culturally rich, place to live.
There is a small but growing presence of foreign residents, particularly from other European countries, who are drawn to Marchena’s relaxed lifestyle and affordable cost of living. This adds a touch of diversity to the town, though the local culture remains predominantly Andalusian in character.
