How are Argentina’s Senate and Chamber of Deputies organized?

Argentina’s legislature, known as the National Congress, is a bicameral body organized into the Senate and the Chamber of Deputies.1

The Senate

The Senate consists of 72 seats. It is organized to represent the provinces and the federal capital, with each province and the city of Buenos Aires electing three representatives to serve six-year terms.21

The Chamber of Deputies

The Chamber of Deputies is composed of 257 members. Unlike the Senate, representation in this house is apportioned according to the population of the provinces. Members of the Chamber of Deputies serve four-year terms.21

Both houses function within Argentina's federal republic framework, which is modeled on the constitution of the United States.1
