Centenarian

A centenarian is a person who has reached the age of 100 years. Because life expectancies worldwide are below 100, the term is invariably associated with longevity. The United Nations in 2012 estimated that there were 316,600 living centenarians worldwide.[1]

As world population and life expectancy continue to increase, the number of centenarians is expected to increase substantially in the twenty-first century.[2] According to the Office of National Statistics in the United Kingdom, one-third of babies born in the country in 2013 are expected to live to 100.[3]

The United Nations estimates that currently there are 573,000 centenarians, almost quadruple the estimate of 151,000 made in 2000.[4] According to a 1998 United Nations demographic survey, Japan is expected to have 272,000 centenarians by 2050;[5] other sources suggest that the number could be closer to 1 million.[6] The incidence of centenarians in Japan was one per 3,522 people in 2008.[7]

In Japan, the number of centenarians is highly skewed towards females. Japan in fiscal year 2016 had 57,525 female centenarians, while there were 8,167 males, a ratio of 7:1. The increase of centenarians was even more skewed at 11.6:1.[8]
