Results include the averages from EL PAIS, The Economist, Globe Elections UN, PollingData, Estadão, Veja, CNN Brasil; and the most recent polls from BTG/FSB, Ipec, Atlas, Genial/Quaest, PoderData, XP/Ipespe, Datafolha y Abrapel/Ipespe. Differences in methodology and how calculations are made (i.e. whether to include undecided voters) explain a large part of the variance between the estimates.
