The proportion of centenarians in the United States is smaller than that of many other developed countries. For example, for every 10,000 people, there are 1.92 centenarians in Sweden, 1.95 in the United Kingdom, and 2.70 in France. And Japan has 3.43 centenarians per 10,000 people, beating even our longest-lived state, North Dakota.
