Is There a Capital of the World?

"Intelligent Life has subjected the contenders to a scoring system that rates them on five attributes (see table below). These are: power and influence (mostly political); income and wealth; educational standards (universities and graduates); cultural life (theatre, publishing, an art scene) and global connections (foreign residents, airports, tourists, foreign languages taught at school, phone calls, internet connections and so on). We have tried to make the scores impartial but some, such as those for power and culture, are inevitably subjective."

Based on this ranking, London comes in first as the world capital, with New York trailing as a close second.
