14. Spain – Median wealth: $95,360
Spain ranks in 14th place overall with a median wealth per adult of $95,360, while its GDP per capita is much lower at $38,118. The country’s wealth isn’t evenly spread, however, with the average gross monthly salary in the northern Basque Country region being $700 higher than in the southwestern region of Extremadura. Economic growth has stagnated lately due to a slowdown in population growth.
