Commonwealth of Nations
The Commonwealth comprises 53 countries, across all continents. The members have a combined population of 2.4 billion people, almost a third of the world population, of which 1.26 billion live in India, 220 million live in Pakistan and 94% live in Asia and Africa combined. After India, the next-largest Commonwealth countries by population are Pakistan (220 million ), Nigeria (170 million), Bangladesh (156 million), and the United Kingdom (65 million). Tuvalu is the smallest member, with about 10,000 people.
State government
The Commonwealth of Australia is a federal nation with six states (and two mainland territories). Section 51 of the Australian Constitution sets out the division of legislative power between the states and the Commonwealth (federal) government. The Commonwealth government is given a variety of legislative powers, including control of foreign policy, taxation (although this cannot discriminate between states or parts of states), and regulation of interstate commerce and corporations. Since the original ratification of the constitution, the High Court of Australia has settled a number of disputes concerning the extent of the Commonwealth's legislative powers, some of which have been controversial and extensively criticised; these included a dispute in 1982 over whether the Commonwealth was entitled to designate land for national heritage purposes under United Nations agreements, as well as numerous disputes over the extent of the Commonwealth's power over trade union and industrial relations legislation.
