This is a work in progress and these GDP numbers are based on research into several govt statistical sources, economic think tanks, chambers of commerce, local business resources etc. In some instances, I was aided by sources citing the percentage of a national economy is represented by a city or metro. Any and all insights and observations are welcomed and in fact requested.
In any event, I used the urban agglomeration map and chart from citypopulations.de to determine population.
I decided to use Nominal GDP instead of Purchasing Power Parity GDP because Im more interested in actual GDP instead of relative GDP.
The only Urban Area whose population I changed was London because I could not find a GDP stat that was similar to the 11 Million pop figure from citypopulations.de, so I combined London and Southeast England's populations and GDP(data from the online statistical portal of the UK govt).
added 10/16/2011. For Paris, the entire population of the Ile de France region was used instead of just the figure provided by citypopulation.de
I am also considering combining the Rhine-Ruhr Area, Milan and its surroundings, Shanghai and more its surroundngs as well as other cities depending on input from other forumers coroborrated by actual data.
For US urban agglomerations, these are the GDP stats for their CSA or uncombined MSA from the Bureau of Economic Analysis of the Commerce Department.
Amounts are in US Dollar using the currency exchange rates for Dec 31, 2010.
Here are the findings so far of the Top 50(actually 51). It could change as I add other cities that I havent calculated yet.
Here are urban agglomerations in the Top 50 as far as population, but not in the Top 50 as far as GDP
The GDP numbers should had been compared on a Purchasing Power Parity basis. Nominal figures can be artificially inflated by controlling the exchange rate to cause such illusion, among other tactics. Such imbalances are removed in PPP.

I actually mentioned that in the first post: I decided to use Nominal GDP instead of Purchasing Power Parity GDP because Im more interested in actual GDP instead of relative GDP.
In actuality, PPP creates illusions because it doesnt just measure just the total dollar value of total economic output(which is what Nominal GDP is), but PPP factors in cost of living and income disparity, ultimately trying to compare countries on as level a playing field as possible, and that is commendable and productive when trying to determine a plan of action to solve issues of socio-economic issues, but that's not my concern here
I want to know total dollar amounts without any factors skewing the outcome.
London has a much higher GDP per capita then that.
Yeah, many of the numbers there do look off. Other sources have different figures.
However, I think focusing on cities and their metropolitan areas is the right idea since so much of the world's population lives in these places nowadays and so much wealth is created and concentrated there.

Yes, the UK Region known as London does yes, but as I incidated above: The only Urban Area whose population I changed was London because I could not find a GDP stat that was similar to the 11 Million pop figure from citypopulations.de, so I combined London and Southeast England's populations and GDP(data from the online statistical portal of the UK govt).
In the interesting of being realistic, I had to add London and Southeast England together because London's area of influence stretches beyond just the UK statistical region known as London.
Otherwise, the London region has a GDP that is approximately 400 Billion US dollars. And I think people would probably have a bigger problem with that than Per Capita GDP.
Any suggestions as far as what areas constitute London would be welcome.
How are Tokyo, New York City, and Ciudad de Mexico metros not part of this list!!? For both population as well as GDP they've got to be top 10.
