Brussels is listed as #11 on The Global Cities Index 2010.
from the article:
So what makes a Global City? Not size alone, that’s for sure; many of the world’s largest megalopolises, such as Karachi (60), Lagos (59), and Kolkata (63), barely make the list. Instead, the index aims to measure how much sway a city has over what happens beyond its own borders — its influence on and integration with global markets, culture, and innovation. To create this year’s rankings, we analyzed 65 cities with more than 1 million people across every region of the globe, using definitive sources to tally everything from a city’s business activity, human capital, and information exchange to its cultural experience and political engagement. Data ranged from how many Fortune Global 500 company headquarters were in a city to the size of its capital markets and the flow of goods through its airports and ports, as well as factors such as the number of embassies, think tanks, political organizations, and museums. Taken together, a city’s performance on this slate of indicators tells us how worldly — or provincial — it really is.
