Are all senate allocations 2 per state?
United States congressional apportionment
United States congressional apportionment is the process by which seats in the United States House of Representatives are distributed among the 50 states according to the most recent decennial census mandated by the United States Constitution. Each state is apportioned a number of seats which approximately corresponds to its share of the aggregate population of the 50 states. However, every state is constitutionally guaranteed at least one seat.
Double dissolution
There have been 7 double dissolutions: in 1914, 1951, 1974, 1975, 1983, 1987 and 2016. However, a joint sitting following a double dissolution pursuant to section 57 has only taken place once, in 1974.In an election following a double dissolution, each state elects their entire 12-seat senate delegation, while the two territories represented in the Senate each elect their two senators as they would in a regular federal election. Because all seats are contested in the same election, it is easier for smaller parties to win seats under the Senate proportional voting system: the quota for the election of each senator in each Australian state in a full Senate election is 7.69% (formula_1), while in a normal half-Senate election the quota is 14.28% (formula_2).
