Because the publishing arm of the Organisation for Economic Co-operation and Development is the most savvy and user-oriented data publisher around (beyond of course my other BFF SimplyMap). What has the OECD done to deserve my love? The OECD Factbook 2009 is now available as an iPhone and iTouch app. That's right dataheads, you can take your economic indicators out on the road with you. Below is a screenshot of the Total Population for the 30 OECD countries and OECD cooperation countries (Brazil, Russia, etc).
While the bar charts aren't visually interesting, it is still pretty nifty to have major indicators from 30 countries at your fingertips (Potentially useful for my bar trivia addicts). I would love to see a more interactive version at some point (e.g., be able to choose specific countries to display and compare). Nevertheless, this e-reference book is a great start. Thanks OECD!
