Worldmapper is a collection of world maps, where [national/country] territories are re-sized on each map according to the subject [data-set] of interest. Maps will be added, and information modified during 2006.

Currently, the 56 online maps feature a diverse range of data-sets, which uses UN data (same basic info as the CIA apparently) include:
Land
Demographics (birth, age, etc.)
Population (various years)
International Refugees / Migration (various)
Tourism $ (various aspects of)
Transportation (various modes)
Communication (various modes)
Imports / Exports (various commodoties)

As more data is entered, more maps will be added.
Each map is accompanied by a printable pdf, an Excel data file with or without the map, and an Opendoc datafile in standard format.

The Univ. of Michigan has a role in the project:

They are copyrighted & are not mass reproduceable. Though other single maps have used one or two sets of data, this is perhaps the most extensive set of maps.

The poster is nice enough to use as a -placemat- at your next missions banquet. Write for permission, then find some generous
businessman with a color printer and a laminator.
