A new Structure of Earnings Survey by Eurostat finds:

The proportion of low-wage earners among employees amounted to 17.2% in 2014 in the European Union (EU). This means that they earned two-thirds or less of their national median gross hourly earnings.

The proportion of low-wage earners continued to vary significantly between Member States in 2014. The highest percentages were observed in Latvia (25.5%), Romania (24.4%), Lithuania (24.0%) and Poland (23.6%), followed by Estonia (22.8%), Germany (22.5%), Ireland (21.6%) and the United Kingdom (21.3%). In contrast, less than 10% of employees were low wage earners in Sweden (2.6%), Belgium (3.8%), Finland (5.3%), Denmark (8.6%), France (8.8%) and Italy (9.4%).
