Difficult to say exactly, because the Census is not very accurate in many countries.

However, they were estimated around 15,000.

Estimation for World Centenarian population around 450,000
Actually, I was being silly before with listing 500 as an answer.
The actual number for USA only was projected in 2000 as 72,000.

However, these numbers vary wildly as the following link is showing a guess-timate of 55,000 in USA is for 2005.

http://en.wikipedia.org/wiki/Centenarian

I quickly did a search that you might want to try:

Type the keyword or keywords in a search engine such as Google or Metacrawler (searcher of all search engines).

Keyword is 'Centenarians' or 'world population of centenarians'.
One such search resulted in this link:

http://www.grg.org/calment.html

"As reported on the front cover of USA Today of August 24, 1999, The U.S. Census Bureau has forecast that the number of Americans aged 100 or older will increase by more than 22 times the 1990 estimate of 37,306. In October 2001, the US Census Bureau actually reported that there were 50,454 US centenarians (a more reasonable 35 percent increase) out of a total population of 281.4 million Americans."

"From present data, the number of worldwide centenarians is around 450,000. However, if one considers only the total number of supercentenarians (100 plus), this number falls dramatically to an estimated 300 to 450 worldwide, of which only approximately 80 are validated."

Thanks for answers I thought(as a uneducated guess) there would be only a few hundred ! -surely there can't be that many people born on 01/01/1900 who were alive on 01/01/2000

I'm sorry...but I'm not sure if you misunderstood something I posted or I misunderstood you. I will clarify (and please let me know what you think...OK?):

The answer is 450,000 people alive of the 100-yr-olds worldwide on 1/1/2000. Then beyond that...of the super-centenarians (100+ to 120 yrs) there's a rapid falloff to down below 300-400 and 80 validated worldwide on 1/1/2000.

I wrote this last night, but decided to wait....

How many people in the world lived to celebrate their 100th birthday on 01/01/2000 ?

I'm reading the question a bit differently, such as....how many people had their 100th birthday on Jan 1, 2000... so just in case that is the question...

One would have to find out how many people were born worldwide in 1900, then divide that by the average percent of the population that lives to be 100 {of people that were born in 1900}...then divide again by 365 to get a per day average.

My guess would be 5 or less...if any.

Edit: I looked for a bit last night, before I decide that I might be reading the question wrong, the only thing I found were stats for Minnesota, saying that only .002 percent of the population that was born in the year 1900, lived to be at least 100.

2packs: I'm not thinking that is the case, but interpretation is a little unclear and needs revisiting by the originator of the thread.

Yeah, I'm still not exactly sure either.

(emphasis mine)

I don't see how there are two possible interpretations of that sentence...? The OP was wondering about people having their actual 100th birthday on 1/1/00, not just turning 100 sometime in 2000, doncha think?

In lieu of your clarification...are you asking about how many of those who are born specfically on the day of 01/01/1900 that actually have that day for a birthdate? Your question seems ambiguous to me...maybe it's just me (and 2 Packs).

I'll try to clear up any confusion Smile

- the question relates ONLY to centurions born on 01/01/1900 AND who were alive on 01/01/2000 -how many of them were they?

Such information for the answer you seek is not available online.

I cannot understand original confusion in my question i've re-read it -it was very clear to me 100% with specific dates.
Why it is "unanswerable" is equally puzzling.At a guess i would say it is a very small number.

Forgive my confusion. Perhaps I just read it too fast.

It is unanswerable as the worldwide list of people who were born on 1/1/1900 is just not readily available online.

Even in USA, where such data is more likely to be kept on computer, you'd have a tough time (as a civilian) generating this data unless you had access to database such as Social Security info or records at City Halls.

Just out of curiosity, why would you need such exacting info? Is this for a school assignment?

I need such info purely for trivia reasons and nothing else! Smile

In fact also want to know same info on people born on 31/12/1899 -who celebrated b/day on 31/12/1999 Laughing

-wouldn't that be fascinating?
I must get out more often Laughing
