According to figures published by the Luxembourg Institute for Socio-Economic Research (Liser), the number of cross-border workers in Luxembourg grew fourfold over that period, compared to a growth in working residents of just 1.7.

“As a result, while cross-border workers represented 26% of the workforce on 31 March 1994, their proportion grew to 46% 25 years later,” Liser wrote in its summary.

The burst of youth from the cross-border working population also gave Luxembourg a respite from the effects of its ageing working population. However, the effects have since evened out. Some sectors are more impacted than others by the ageing working population. “That is why active ageing remains as much a national as a European stake, and for everyone (workers, companies and politicians),” the report read.
