Note

Of the 570,660 migrants who were detained in 2009 in the 27 EU Member States, 252,785 were deported to their country of origin. The United Kingdom (64,945) and Greece (62,850) carried out the most deportations. Although, in certain countries such as Romania, the Netherlands, Poland and the United Kingdom, a period in detention generally results in deportation, this is not the case in countries like France, Italy, Portugal, Greece or Germany, which detain many more persons than they deport. Finally, in countries like Poland, the Netherlands, Romania and Slovenia, the number of deportations exceeds the number of detainees; house arrest and refusal of entry at the border [1] may partly explain these differences.
