Non-EU citizens aged 20-64 were in 2013 twice as likely (21.3%) to be unemployed in one of the EU's 28 member states compared to "nationals" (10.0%), new data from the EU's statistics office Eurostat shows.

The data also revealed that the employment rate was 56.1% for non-EU citizens, compared with 68.9% for citizens of the reporting country.

But large differences can be found within member states.

In Sweden, which has the biggest gap, the employment rate for non-EU citizens was 50.2% compared with 81.3% for nationals (-31.1 percentage points), followed by Belgium (-28.8), the Netherlands (-26.8), France (-22.0), Finland (-20.5) and Germany (-20.2).

Meanwhile, some countries are experiencing a higher employment rate of non-EU citizens than for nationals, for example in Cyprus (66.8% for nationals compared with 74.3% for non-EU citizens), the Czech Republic (72.4% compared with 79.5%), Lithuania (69.8% compared with 70.8%) and Italy (59.5% compared with 60.1%).

The Eurostat data also highlighted that migrants from another EU country have the highest employment rate.

In 2013, the employment rate for citizens of another EU member state (70.9%) aged 20-64 was slightly higher than that for citizens of the reporting country (68.9%) in the bloc's 28 countries.

The unemployment rate was  bit higher (12.2) on average for citizens of another EU member state than for nationals (10.0%) though the share of long-term unemployment was however notably lower for citizens of another EU member state (40.0%) compared to the rate for nationals (49.4%).
