The world population is soon set to exceed 7 billion, with population growth doubling in the last 50 years. Enter your date of birth to see what number you are. (When I was born born, I was the: 2,467,548,778th person alive on Earth and the 75,440,962,022nd person to have lived since history began)

When you were born, you were the:
2,290,796,387th
person alive on Earth
74,767,125,989th
person to have lived since history began

Am I alone in thinking that doesnt seem like so many? I thought it would be an unrecordable number somehow... weird.

The trouble is that the amazingly precise-looking numbers are based on estimates. (After all, in various places and at various times there were no full records of births - or no records at all). I suppose it might be more accurate to give a likely range, but that would spoil the fun. wink

I was the 4,463,334,345th person born on Earth. In the amount of time it took to figure that out the population increased by 81. How do we feed everyone?

ren, I think it's because it's only once the numbers got big that it really got going. The rate of increase is interesting to track - here's what Wiki has to say:

"It is estimated that the population of the world reached one billion for the first time in 1804. It would be another 122 years before it reached two billion in 1927, but it took only 33 years to rise by another billion people, reaching three billion in 1960. Thereafter, the global population reached four billion in 1974, five billion in 1987, six billion in 1999 and, by some estimates, seven billion in October 2011"

So it took however many millions of years to get to one billion, 122 years to get to two, and now we're adding another billion every decade or so.

Yeah, because I've kinda grown fond of my own personal number. LOL laugh

Ren, maybe one reason it doesn't look so many is because you're British and we don't count billions like that - the figures shown are mere thousand millions, not million millions. And I am shocked that Auntie BBC has become so Americanised it shows figures like that and says they're billions without even blushing. Shame on you, Auntie Beeb, shame! tongue wink

I just did an interesting exercise that might open your eyes a bit about large numbers.

Imagine if everyone alive today (say, 7,000,000,000) occupies a single square metre of earth. Which country would you be able to fit the entire population in, and still have room to spare?

Russia? Australia? India? Greece? Puerto Rico? Hong Kong?







7,000,000,000 square metres is equal to 7,000 square kilometers or 2700 square miles.

Believe it or not, with an area of 8,800 sq km (3,400 sq miles), Puerto Rico could accommodate ALL of us, and still have over 1,800 square kilometres (700 square miles) left over.

I can't tell you what my numbers are because then you'd know my age! LOL

I'm number 3,102,512,177 and 76,812,982,215th.

I wonder how much uncertainty there is in these numbers? :-)

I try to get my students thinking about the uncertainty in their answers (especially those copied straight from excel spreadsheets!)

I reckon there must be at least an uncertainty of 1% (and that would be extremely precise for this sort of thing) so really I'm somewhere between 3.07 and 3.13 billion....
