Stats of the Union [fathom.info] by Ben Fry's Fathom Information Design reveals the vital health signs of the U.S. on the iPad. The interactive visualization provides a geographical view on various detailed statistics, such as population demographics, risk factors and indicators of health, all aggregated per county.
Proud iPad owners can now explore the geographical distribution of age, population density or ethnicity, check how people are born (e.g. by parameter like birth weight, premature births) versus how they die (e.g. by cause like homicide, car crashes, heart disease). The population can be filtered by disease, preventative procedures or risk factors, and many other relevant parameters. In addition, interesting views or patterns can be saved and exported.
Let's hope larger screenshots and/or a movie will be released soon, for those without direct access to a tablet computer.
