Betel is a district of Paulínia, located 5 km to the East of Paulínia downtown, bordering the Campinas district of Barão Geraldo. Its area is about 49.5 km2 and it had a population of 6,242 at the time of the 2010 IBGE census. In 1993, the region was part of the district of Barão Geraldo in Campinas. That year, a referendum concerning its accession to Paulínia was held, as Betel was economically very attached to the city; the population voted to join the Paulínia municipality, which subsequently expanded in area.
