Most sources report Argentina's population as 97 per cent white (mostly of Spanish and Italian descent) and three percent mestizo (Amerindian' and European), Amerindian, or other nonwhite groups. One of the difficulties in assessing and addressing persistent forms of racial discrimination in Argentina is the lack of adequate information about the population, particularly the indigenous and immigrant communities. The national census scheduled for 2000 was postponed due to lack of funds. Historically, national census data has been collected using the category of national origin rather than race in Argentina, leading to undercounting Afro-Argentines and mestizos.
