Recently the population of the earth exceeded 7 billion.
There is a cool page on BBC that you can link to here to find out some stats on yourself and the country in which you live.
When I was born, I was the:
3,793,054,066th person alive on Earth and the 77,990,203,579th to ever be born.
Interesting isn't it?
You can get more information on the page about the country in which you live. I entered Zimbabwe because although I don't live there now, it is where I am from.
I thought it was interesting that the life expectancy of women in Zimbabwe is 45.5 years. Thankfully I no longer live there, but reside in Canada where my life expectancy is almost double.
