UN predictions indicate that in 2050, the demographics of urban areas will be fairly equal to the total population of the world in 2002. With constant development of the cities, economic, social and creative opportunities increase which forms the major attraction for the inflow of population.
As per the estimates from McKinsey, the top 600 cities in the world will account for 60% GDP by 2025. In no time, the smart city industry will be a $400 billion market by 2020. But the fact still remains that urbanisation comes hand in hand with some major challenges which are faced commonly by the world’s fastest growing cities.
