If you’re in London, Los Angeles, Singapore or Sydney your city is in the top 20 as it was in 2008, the first (and only other) list put together by this group. Moscow missed the top 20 this time moving from 19 to 25. Frankfurt and Shanghai appeared tied at 20 (or one is 20 and the other 21 – you can decide.).
The last on the list? That was Chongquing which wasn't on the list in 2008 (which only had 40 cities listed.) That year Kuala Lumpur was # 40 (now # 48) and this year #40 is Atlanta.
Not simply a list based on population but rather an analysis of 65 cities with populations of over a million ranked using “25 metrics across five dimensions”. (http://www.foreignpolicy.com/articles/2010/08/18/global_cities_index_methodology). The metrics include, as you’d expect, the measure of business activity, human capital, and how freely information flows into and out of the city. Beyond these basics they considered cultural experience (sporting events and diversity of restaurants) and political engagement such as international organizations based there and the perceived influence the city on our global dialogue.
Look to see where your favorite city ranks overall and then explore where it is on the dimensions that you consider most important. What make a city global for you?
