This study is one of the first attempts to measure participation by th
e Brazilian population in the elections during the country's Imperial
Period. Based on 1880 voter registration lists from the city of Sao Pa
ulo, the author calculates both the proportion of voters vis-a-vis tot
al population and their socio-economic characteristics, including age,
income, occupation, literacy, and place of residence. This model stud
y makes a comparison between Sao Paulo's more wealthy urban parishes a
nd the poorer rural ones and identifies significant differences in the
respective voting populations. Recalling earlier work done on late 19
th-century voter and National Guard lists from the States of Minas Ger
ais and Parana, the author shows that Sao Paulo had comparable rates o
f voter activity, all of which suggests significant participation by p
oor working class males in the electoral process.
