Datafolha is one of the most important and complete research institutes in the country. Created in 1983 as a study department on public and electoral opinion for the Folha Group, it earned more notoriety after the 1989 campaign, when the country returned to direct presidential elections.
That year, it was the only institute to predict, based on exit polls, the two candidates that advanced to the second round (Fernando Collor de Mello and Luiz Inácio Lula da Silva).
In 1990, it began to serve outside customers, such as banks, supermarkets, factories, advertising agencies and media companies that wanted to improve services, strategies and marketing plans. It is characterized by technical rigor and the agility with which it performs its work.
Datafolha doesn't accept orders for research on voter intentions, or government evaluations done by candidates, political parties or financial institutions.
