Residents are sometimes referred to as Franciliens, an administrative word created in the 1980s. The GDP of the region in 2019 was nearly one-third of the French,: 12  and 5% of the European Union's.: 12  It has the highest per capita GDP of any French region and the third highest of any region in the European Union.Beyond the city limits of Paris, the region has many other important historic sites, including the palaces of Versailles and Fontainebleau, as well as the most-visited tourist attraction in France, Disneyland Paris.
