Top 100 Powerful Cities of the World

Here is my list of the Top 100 Cities of the World.  This is based on several criteria, sometimes competing.  In general it is ranked by GDP, with adjustments for other factors, such as political power. For instance, Washington and Brussels are ranked higher for political reasons. I think it is pretty good for a first pass and it is subject to change.

Of this number, 24 are in the United States and Canada, 3 in Central America and the Caribbean, 7 are in South America, 28 are in Europe (including Russia & Turkey), 3 are in Africa, 6 are in the Middle East and 29 are in Asia (including India & Australia).
