How the world's cities have fared since the financial crisis hit in 2007

CITIES are the great engines of growth in the world economy. Istanbul, with income growth of 5.5% and employment growth of 7.3% over the past year, is currently the world's best-performing city, according to a new report by the Brookings Institution and the London School of Economics. The report ranks 150 cities from across the globe according to growth in gross value added per person (a proxy for income) and employment. The 150 metropolitan areas represented just 12% of the world's population but accounted for 46% of the world's GDP in 2007. Some cities have plunged in the rankings since the "Great Recession". Dubai and Dublin, the second and sixth best-performing cities respectively between 1993 and 2007, now rank as the most stagnant.
