World Population is a graphic simulation of human population growth over two millennia, developed by Population Connection. As the years roll by on a digital clock from 1 C.E. to 2050, dots light up on a global map to represent population change (1 dot = 1 million people). The mapped population dots were created from a unique dataset that was compiled from a number of government and academic sources (see a listing at www.WorldPopulationHistory.org).
