Blacks to outnumber whites in Brazil...?

According to the Brazilian census Blacks make up 6% of the population. Unless Whites share of the population is even less than 6% which according to the IBGE they aren't, than I don't see how Blacks outnumbering Whites is accurate. I think the article is misleading and should have replaced Black with Brown/Mixed Race since it's Brown people that are quickly catching up with the White population.
