The first person to live to over 150 years of age has already been born. This, according to the Strategies for Engineered Negligible Senescence Foundation.
The United Nations says that by 2050 there will be 2.2 million people in the world who are over 100. That is as many people as the entire population of Houston. The figure for the number of humans aged 100 or older in the world today is about 300,000.
24/7 Wall St. looked at statistics on centenarians in the 15 largest nations by GDP. Then we took the 11 countries that are also OECD members because the organization keeps data on life expectancy and heath care expenditure per GDP, two sets of data that are essential to an analysis of why people tend to be long-lived. The common data among all countries allowed 24/7 Wall St. to give some context to the number of people who are over 100 in each country. Not having the common data ruled out China and Brazil. China says it has over 43,000 centenarians; Brazil has over 23,000. That would put both nations in the top ten.
Scientists and doctors are as yet unsure about the causes of longevity — whether it is superior genes or substantially better lifestyles. The debate will probably continue for some time.. Medicine has not been able to determine how to make any individual live longer than people who live in the same place and have many of the same traits. So, the medical mystery will continue.
Despite the drawbacks of research, the United Nations believes it can project how large the population of people over 100 will be four decades from now. The global agency reports:
In 1998, there were 135,000 centenarians in the world. By 2050, there will be 2.2 million centenarians, that is one of every 5,000 people. The largest centenarian populations in 2050 are projected to be in China with 472,000, the United States with 298,000, Japan with 272,000, and India with 111,000. By 2050, Japan will have the highest proportion of centenarians, 2.6 per thousand of the total population, or 2.2 per cent of the oldest-old. Its total number of centenarians will be 272,000: 40,000 males and 232,000 females. Finland, Italy, Norway, Singapore and Sweden will have slightly below two per one thousand people.
There are a number of reasons to believe that the count of centenarians by country is inexact. The first is that census data collection is uneven and therefore cannot be reliably compared between countries. There is also some amount of research that shows that people will exaggerate their age as much as they do their incomes and the frequency with which they have sex. People over 100 receive much attention, which is a good reason for people who are in their late 90s to lie.
24/7 Wall St. used OECD data to determine health care spending as a percentage of GDP, average life expectancy, and GDP per capita for the countries on this list. The data on centenarians came from census bureaus and government agencies from the various countries. There is every reason to believe that as the availability of modern medicine becomes widespread, the concentration of people that are over 100 years old in non-OECD nations will begin to rival those who live in the developed world today.
These are the countries with the most people over 100.
