South Asians also left descendants in Brazil, although more recently than East and West Asians. Currently, there is an influx of Bengalis, most of them refugees. There are no studies, however, over how South Asians are classified in the Brazilian typical racial system, and it is possible that South Asians arenot be included into the category "yellow" category of skin colour, which is usually used as a proxy to quantify the population of Asian ancestry (other than West Asian) in Brazil.
