Between 2012 and 2016, Belgium's gross domestic product (GDP) was 3.5 percent higher than it would have been if there had been no immigration to our country during that period. This additional growth came from both EU and non-EU migrants. During those years, migrants paid more on average in taxes and social security contributions than they cost in benefits and public services.
Their income, not just tax contributions, also get spent to mostly support of other Belgian interests/employees.
