From: The top 1%: quantifying the unequal distribution of malaria in Brazil
Cumulative distribution of malaria cases at varying spatial scales in the Amazon Basin. Three administrative levels (state, municipality, health unit) are considered, corresponding to different spatial resolution. Administrative units are ranked according to P. vivax or P. falciparum transmission intensity. For example, 80% of P. falciparum cases in 2004 could be found in municipalities containing 20% of the population in the Amazon Basin
