As the world welcomed the 7th billion person on last Monday, the UNFPA (United Nations Population Fund) and BBC launched a new initiative called 7 Billion People and You with the purpose of putting you in perspective to the rest of the world and finding your place on the list, to give you a unique number.
With this application you will be able to relate your own personal characteristics, such as your sex, age, date and place of birth, as well as current residence to the situation of the world’s 7 billion people. You might be surprised at what you will find out.
What you have to do is plug in your birthday, place of birth, sex and other basic information and the application will estimate how many people were alive on earth when you were born, and the total number of people who walked this planet since the early home sapiens. Needless to say these are just estimates, but the best guess that is possible using archaeological evidence and modern census.
You can grill down the data by continent, country and the city your were born. Lots of detailed figures are available. Also checkout the BBC’s version of 7 billion people and you, that provides a different set of data.
