Heard about this project on NPR. "Worldmapper is a collection of world maps, where territories are re-sized on each map according to the subject of interest...The maps presented on this website are equal area cartograms, otherwise known as density-equalising maps. The cartogram re-sizes each territory according to the variable being mapped...The process of creating an equal area cartogram is not a trivial one, and has occupied researchers for decades. A recent development by Mark Newman and Michael Gastner (described in their paper, Gastner and Newman 2004) has led to the creation of this website. The process is essentially one of allowing population to flow-out from high-density to lower-density areas, and they used the linear diffusion method from elementary physics to model this process."

HIV prevalence

"In 2003, the highest HIV prevalence was Swaziland, where 38%, or almost 4 in every 10 people aged 15 to 49 years,were HIV positive. All ten territories with the highest prevalence of HIV are in Central and Southeastern Africa."

Violent Deaths (2002)

Gotta love Europe when it comes to violence (or lack thereof). Stay away from Colombia. And from everything I've been hearing, the mafia and murderers of Juarez are trying to push Mexico up in the rankings. Dark humor, I know.

Odd fact that I didn't know: Norway is the 2nd leading exporter of crude petroleum to the world (#1 is Saudi Arabia - exporting 2x as much as anyone else).

Best feature of the website: for each map, you can make a printable PDF poster for your classroom/dorm/apartment/rebel base.
