The Demic Atlas Project:
Toward a Non-State-Based Approach to Mapping Global Economic and Social Development
by Martin W. Lewis, Jake Coolidge, and Anne Fredell
The Spatial History Lab at Stanford, which has provided extensive technical assistance, will eventually publish the maps as an on-line document. GeoCurrents will also post maps from the project, as well as commentary on the process. Beginning today, I will discuss both the intellectual rationale for such an atlas and the problems that we have encountered in creating it.
For starters, they are simply not comparable entities, varying enormously in both area and population. We know this, but we rarely let it truly sink in. Consider the discrepancy between China, with 1.3 billion inhabitants, and Tuvalu, with ten thousand. Comparing these two independent states is like weighing a single person against a city of 130,000.
No serious study would ever make such a comparison, spanning more than five orders of magnitude. Yet when it comes to assessing the economic and social conditions of the world, making such gargantuan leaps in scale is the price we pay for using country-based data.
In actuality, the total population of the forty-nine top entries is less than ten per cent of the global sum. That is not exactly a stellar showing for the U.S., especially considering the fact that it is bested by several much poorer countries, including Jordan and Bosnia. Still, the fiftieth-place position indicated by the Factbook is misleadingly low.
Such an inclusive approach is beginning to be followed by other major data sources as well, no doubt from a desire to be fair and comprehensive. Just because Greenland and Guernsey lack full independence is no reason to consign them to statistical oblivion. In the process, however, the problem of incomparability is compounded.
When overall per capita GDP is calculated in terms of purchasing power parity, China’s $7,500 figure ranks well below the global average of $11,100. But the commercial core areas of eastern China, increasingly vital drivers of the world economy, evince per capita GDP figures well above the world average, reaching $13,000 in Jiangsu, $18,500 in Shanghai, and $46,000 in Hong Kong.
