One vote, one value

In Australia, one vote, one value is a democratic principle, applied in electoral laws governing redistributions of electoral divisions of the House of Representatives. The principle calls for all electoral divisions to have the same number of enrolled voters (not residents or population), within a specified percentage of variance. The electoral laws of the federal House of Representatives, and of the state and territory parliaments, follow the principle, with a few exceptions. The principle does not apply to the Senate because, under the Australian constitution, each state is entitled to the same number of senators, irrespective of the population of the state.
