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.
Commonwealth (U.S. state)
Two U.S. territories are also designated as commonwealths: Puerto Rico and the Northern Mariana Islands. When used in connection with areas under U.S. sovereignty that are not states, the term broadly describes an area that is self-governing under a constitution of its own adoption and whose right of self-government will not be unilaterally withdrawn by the United States Congress.
