AFP, Brussels :
Of the more than 500 million people in the European Union, some 34 million or less than seven percent are counted as migrants.
Of that total, 14.3 million are EU citizens who have taken advantage of the bloc’s free movement possibilities, while just under 20 million come from third countries outside.
Here is a breakdown of Europe’s migrant numbers:
Some of the smaller EU countries, led by one of the smallest of all, Luxembourg, have opened their doors widest in proportion to their demographic size.
More than 45 percent of the population of Luxembourg are foreigners, attracted by its high standard of living, according to the EU’s statistical agency, Eurostat.
Cyprus follows on 19.5 percent, Latvia 15.2 percent, Estonia 14.9 percent, Austria 12.5 percent, Ireland 11.8 percent and Belgium 11.3 percent.
In eastern Europe, however, Poland, Romania, Croatia, Lithuania are all less than one percent.
Poland in turn is one of the largest sources of citizens living in other EU countries, ranking in the top five in 10 member states.
The number of short-term foreign workers in EU countries is surprisingly small despite a 60-percent increase from 2010 to some two million in 2015.
Sent by their employer to work in another member state, this category accounts for less than one percent of jobs in the EU, concentrated largely in construction and manufacturing.
