Never saw this before: The Worlds Population by Latitude and Longitude.
And another interesting fact about world Population (and well worth an infographic): 44 % of the world's population (more people than inhabited the entire globe in 1950) live within 150 kilometers of the coast. In 2001 over half the world's population lived within 200km of a coastline. The rate of population growth in coastal areas is accelerating and increasing tourism adds to pressure on the environment.
