Click on World Population Clock to get the latest figure and watch it click on at more than 2 births per second! Put in a future date and scare yourself some more. What is Mother Earth going to do about this ???
Those familiar with the earlier version will note that the range in which the new version gives reasonable estimates has increased considerably. It is of some interest to note that this approximation predicts that the population will start decreasing before the end of the 21st century.
The raw data is from the U.S. Census Bureau, and is not uncontroversial. For instance, the UN, with its data, considered 1999 October 12 to be the “day of six billion”, but the approximation here (which I for one have more faith in) puts it at 1999 June 18 or 19 (depending on what time zone you’re in), nearly four months earlier.
