Striking how stark the differences between Northern/Central and Southern/Eastern Europe are when it comes to the share of students who have jobs! This map shows only the share of the employed, however, in Northern European countries many students are still unemployed, meaning that they are looking for work but at that moment did not have one. The share of those can be as high as 14% in Sweden, 9% in Finland and 7% in the Netherlands. It means that over 3/4 of all students in the Netherlands want/need to have or already have a job!
