Mega Cities have populations of more than 10,000,000 and are located in rapidly urbanising emerging markets.
Beijing leads the group, receiving an overall score of C+, while Mumbai and São Paulo each receive a C. As Mega Cities continue to boom, propelled by industrialisation and mass migration from rural areas, low incomes and rapidly rising populations are proving particularly challenging in terms of improving networks and ensuring that basic infrastructure meets demands in these cities. However, innovative new uses of data and apps to improve connectivity in a cost-effective way are helping these cities gain pace with global competitors.
