Eurostat has published the data on per capita disposable income for the countries of the European Union up to the year 2022. This refers to the resources available to individuals, including salaries, capital income, public aid, and other income.
In 2022, the per capita income (net disposable income) of Spain was €16,800 per year, which represents 86.6% of the average for the European Union of 27 countries. That is, 13% less.
Two decades ago, there were seven autonomous communities with a per capita income higher than the European Union average; now there are only two: the Basque Country and Madrid, by 6% and 13% respectively. The five that have lost this status are Catalonia, Navarre, La Rioja, Aragon, and the Balearic Islands.
All Spanish autonomous communities have lost ground in this period, except for three: Asturias, Galicia, and Extremadura.
