What is the average Belgian salary?

What are the criteria that define a high, median or low salary? According the latest statistics from 2019, a full-time worker earns an average of 3,758 euros gross per month. But this amount is nevertheless biased. In fact, 60% of Belgians earn less than this amount. In question, the high incomes, the 9% of Belgians who earn more than 6000 euros gross per month, which increase the average.

What figure should be used then? Rather than the average salary, the best indicator is the median salary.
It is 3,486 euros gross per month. It is really central because 50% of Belgians earn less than this amount, 50% earn more. Net, this corresponds to approximately 2250 euros monthly.
