Centenarian
From Wikipedia, the free encyclopedia
A
centenarian is a person who lives to or beyond the age of 100 years. Because
life expectancies everywhere are less than 100, the term is invariably associated with
longevity. A
supercentenarian
is a person who has lived to the age of 110 or more, something only
achieved by about one in 1,000 centenarians. Even rarer is a person
who has lived to age 115 – there are only 36 people in
recorded history who have indisputably reached this age, of whom only
Jeralean Talley,
Susannah Mushatt Jones,
Emma Morano-Martinuzzi, and
Violet Brown are still living.
[1][2][3] In 2012, the
United Nations estimated that there were 316,600 living centenarians worldwide.
[4]
As life expectancy is increasing across the world, and the world
population has also increased rapidly, the number of centenarians is
expected to rise fast in the future.
[5] According to the UK
ONS, one-third of babies born in 2013 in the UK are expected to live to 100.
[6]
The
United States currently has the greatest number of known centenarians of any nation with 53,364 according to the
2010 Census, or 17.3 per 100,000 people. In 2010, 82.8% of US centenarians were female.
[7] Japan has the second-largest number of centenarians, with an estimated 51,376 as of September 2012,
[8]
and the highest proportion of centenarians at 34.85 per 100,000 people.
Japan started recording its centenarians in 1963. The number of
Japanese centenarians in that year was 153, but surpassed the 10,000
mark in 1998; 20,000 in 2003; and 40,000 in 2009. According to a 1998
United Nations demographic survey, Japan is expected to have 272,000 centenarians by 2050;
[9] other sources suggest that the number could be closer to 1 million.
[10] The incidence of centenarians in Japan was one per 3,522 people in 2008.
[11]
Centenarian populations by country
The total number of centenarians in the world remains uncertain. It
was estimated by the Population Division of the United Nations as 23,000
in 1950, 110,000 in 1990, 150,000 in 1995, 209,000 in 2000, 324,000 in
2005
[12] and 455,000 in 2009.
[13]
However, these older estimates did not take into account the
contemporary downward adjustments of national estimates made by several
countries such as the United States; thus, in 2012, the UN estimated
there to be only 316,600 centenarians worldwide.

The following table gives estimated centenarian populations by country,
including both the latest and the earliest known estimates, where
available.
