INFO: This applet uses a logarithmic equation obtained through a statistical analysis of the data at the following URL: http://www.census.gov/ipc/www/worldpop.html. As this is a regression, it may not match the figures from the above URL exactly. This figure does take into account both births and deaths, for those that have asked. And, yes, while the count may not be exact, there really are, more or less, that many people on the planet.
