This week the world hit the 7 billion population mark and to mark the dramatic occasion, NPR created this very cool interactive map to as part of their special series, “7 Billion and Counting.”  The map allows users to easily compare each country’s fertility policy, population density, and GDP.

We also love this video that demonstrates the history of world population growth.  It’s a great visual resource to help your students fully grasp what 7 billion really means!
