The Global Power Cities Index is determined by various factors in six broad categories: cultural interaction, research and development, livability, environment, and accessibility. First published in 2008, the index also features actor-specific ranking and key findings – looking at perceptions of each city from the viewpoint of actor groups like managers, artists, researchers, visitors and residents.

Although Joburg ranks at the bottom of the index across many categories, its inclusion on the index is recognition of the city’s growing status as a powerful city in the global environment.

The top five power cities, reflecting the same trend since the index launched, have remained fairly stable without much change among them.

London has been ranked the most powerful city in the world after it took the top spot from New York in 2012.
