Cities preferred by world's wealthiest people

While much of the wealth creation is taking place in the world’s new economic powerhouses, New York and London are still considered the most important cities for the super-rich – at least for now.
Knight Frank’s Global City Survey examines four key themes: economic activity, political power, quality of life and knowledge and influence.
Note: For each theme, every city is ranked from one (strongest) to 40 (weakest).
