Most of Vargem Grande do Sul's inhabitants descend from European immigrants, especially from Italy. Italian family dominate the register of the municipality. Significant families include the Baizi, the Bassi, the Beloni, the Bortoloto, the Buzato, the Canal, the Coracini, the Cossi, the Filipini, the Longuini, the Lupetti, the Marquesini, the Menossi, the Molinari, the Nardini, the Pratali, the Pecinato, the Rocchetto, the Sartori and the Sbardelini. At the beginning of the 20th century, some of those families, and others, founded the mutual aid "Società de Mutuo Socorso" to help members, offering among other services free health care and coffins. The organization continues to hold dinners and dances. At the time of the
Second World War, the Brazilian government prohibited the use of enemy languages in the country, such as Italian and German spoken so widely at the time, so it was renamed "
Sociedade Beneficente Brasileira". The change was imposed on many institutions and associations throughout Brazil; state capital football team Società Esportiva Palestra Italia became
Sociedade Esportiva Palmeiras. The municipality's population has historically middle class, showed little social segregation and has a peaceful profile. == Dialect ==
