World’s fastest-growing cities

What to study?

For Prelims: About the survey and top performers.

For Mains: Fastest growing urban areas- meaning, challenges and ways to address them.

Context: Three Indian cities have been listed as the world’s fastest-growing urban areas, a survey by the Economist Intelligence Unit (EIU) revealed.

 How are the cities ranked?

Cities are ranked based on “Total % change, 2015-20 forecast”.

The list is based on data from the United Nations Population Division.

The Economist has listed the rate at which the populations of the “urban agglomerations” (UA) are expected to increase between 2015 and 2020.

 Key facts:

  • Malappuram, Kozhikode and Kollam were the only three cities to make it to the top 10 of the world’s fastest-growing cities.
  • Malappuram was ranked No. 1 in the world rankings with a 44.1 per cent change between 2015 and 2020.
  • While Kozhikode was ranked fourth with 34.5 per cent change and Kollam was at number 10 with 31.1 per cent.

Why then are Malappuram (44%), Kozhikode (34.5%), and Kollam (31%) growing so fast?

These cities are seeing rapid urbanisation, and the main reason is the inclusion of new areas in the UA’s limits.

  1. In 2001, there were two municipal corporations within the UA of Malappuram. In 2011, the number of municipal corporations had doubled to four, and an additional 37 CTs were included within Malappuram. The population of the UA (excluding the residents of the outgrowths) increased almost 10 times in the same period — from 1,70,409 to 16,99,060 — obviously because of the inclusion of existing urban areas in the town.
  2. Similarly, Kollam UA grew from one municipal corporation in 2001 to 23 CTs, one municipal corporation, and one municipal council in 2011. Its population increased by 130%, even though the population of the original ST of Kollam actually decreased by 4%.
