World Clock

The stats in the World Clock updated as of July, 2010, using several resources for statistical data:

* World Health Organization
* CIA Factbook
* US Census bureau
* UK HomeOffice
* Avert.org
* International Union Against Cancer
* StateMaster
* NationMaster
* Center for Immigration Studies
* National Wildlife Federation
* EarthPolicy.org
* Wikipedia

We will do our best to keep this data current. This is not an easy task as much of it varies widely throughout the year and many sources report contradictory figures. We recommend that you double-check any stats with other sources.
