Brazil
In Brazil, seats in the lower chamber of the federal congress (Câmara dos Deputados) are split throughout the 26 States and the Federal District in a roughly proportional manner. Each federal entity has a minimum of 8 seats and a maximum of 70. The States of São Paulo and Minas Gerais have the largest number of seats. Within each federal entity, representatives are chosen by open-list proportional voting.
For the senate, each federal entity (state or federal district) has a fixed number of three senators.
