Roman Catholicism has traditionally been Belgium's majority religion; being especially strong in Flanders. However, by 2009 Sunday church attendance was 5% for Belgium in total; 3% in Brussels, and 5.4% in Flanders. Church attendance in 2009 in Belgium was roughly half of the Sunday church attendance in 1998 (11% for the total of Belgium in 1998). Despite the drop in church attendance, Catholic identity nevertheless remains an important part of Belgium's culture.
