New Delhi. Besides the big metros, two cities – Surat and Pune – have emerged as biggest destinations for migrants in India, even as interstate migration has doubled between 2001 and 2011 compared to last decade, a new study by the World Economic Forum has said.

Of the total population of over 50 lakhs of Surat, 58% comprise migrants from other states of the country like Maharashtra, Andhra Pradesh, Odisha, Bihar, Uttar Pradesh and Rajasthan. Similarly, Pune attracted 6.60 lakhs migrants in 2011, which is 21% of its total population. It was up from 3.70 lakh (14%) in 2001.

The WEF report on “Migration and its impact on cities” analyses the story of migration of 22 cities of the world. In the Asia region, the report studied Guangzhou in China and Davao City of the Philippines, besides Surat and Pune.
The report studies the types, patterns and causes of migration, cities most affected by it and its impact on the urban infrastructure. It also looks at how the cities are meeting the challenges emerging out of the excess population and presents a framework to achieve long term migrant integration.

Out of the 100 fastest growing cities in the world, 25 are in India with Mumbai and Delhi and Kolkata being among world’s 10 most populous urban spaces, the report notes.

People, mostly poor, from rural and backward areas keep migrating to cities in the hope of getting jobs, enhancing income and the quality of life and having access to better urban infrastructure in health and education for children. However, in the process, the cities drawing the migrants face the challenge of meeting the requirements of added population.

According to the WEF, the world has more than one billion migrants, a seventh of the globe’s population. Over 76% of the total migration in the world is internal migration, but it receives less attention of world leaders than the international migration.
