The World Population Clock

by Germán and Nicolás Rodríguez

If you have a java-enabled browser you will see our World Population Clock dynamically updated at every tick of the clock.

This clock is synchronized with the World Population Clock at the U.S. Census Bureau, and provides essentially the same estimate of the population of the world for any time between July 1, 2011 and June 30, 2012. (Last updated July 16, 2011.)

To launch the Population Clock on a small popup window click here.

For more information on world population data and population clocks, visit the U.S. Census Bureau website.
