Belgrade is home to many ethnicities from across the former Yugoslavia and the wider Balkans region. The main ethnic groups are: Serbs (1,505,448), Roma (27,325), Montenegrins (9,902), Yugoslavs (8,061), Croats (7,752), Macedonians (6,970), and ethnic Muslims (3,996). Many people came to the city as economic migrants from smaller towns and the countryside, while tens of thousands arrived as refugees from Croatia, Bosnia-Herzegovina and Kosovo, as a result of the Yugoslav wars of the 1990s.
