The number of cross-border workers coming to Luxembourg is growing tirelessly. The only minor drop occurred in the second quarter of 2009. The same year, the number of foreign residents in Luxembourg went down briefly in what seem to be developments linked to the economic crisis in 2009. Furthermore, over 70% of registered unemployed in the Grand Duchy are non-nationals.

Today, Luxembourg employs 177,110 frontier workers, up from 88,631 in 2000. During the third quarter of 2016, French frontier workers were close to a number of 90,000 to be employed in Luxembourg. This number almost doubled in 15 years (around 46,000 in 2000).

Belgian cross-border workers, representing 25,000 employees back in 2000, are today close to 43,000 to have their income in Luxembourg. 16,000 Germans made the trip to Luxembourg in 2000, which also rose to 43,000 today. Compared to the other neighbouring countries, this was the strongest increase in a period of 16 years.
