The China Data Center at the University of Michigan, an exhibitor at the recent AIIP conference in Pittsburgh, has published a PowerPoint presentation titled "A Quick Assessment of Potential Population Affected by the Earthquake of
Sichuan, China." Drawing on its database, the slides show where the May 12th earthquake happened and the population characteristics of the area. It’s a wonderful piece of work and very valuable for those with minimal knowledge of that part of the world.
