, however, and because the Argentine population doubled every twenty years from 1870 to 1930 as a result of Immigration in Argentina, immigration (disproportionately benefiting Buenos Aires and the Pampas area provinces), censuses were conducted generationally, rather than every decade, until 1947.Indec: Historia de los censos

Apportionment controversy

The distribution of the Chamber of Deputies is regulated since 1982 by Law 22.847, also called ''Ley Bignone'', enacted by the last Argentine dictator, General Reynaldo Bignone, ahead of the 1983 Argentine general election, 1983 general elections. This law established that, initially, each province shall have one deputy per 161,000 inhabitants, with standard rounding; after this is calculated, each province is granted three more deputies. If a province has fewer than five deputies, the number of deputies for that province is increased to reach that minimum. Controversially, apportionment remains based on the 1980 population census, and has not been modified since 1983; national censuses since then have been conducted in 1991, 2001, and 2010. The minimum of five seat per province allots the smaller ones a disproportionately large representation, as well. Accordingly, this distribution does not reflect Argentina's current population balance.

Presidents of the Chamber
