United Nations - World Urbanization Prospects - 2014 Revision

esa.un.org - Press Release (excerpt)

UN finds world's population is increasingly urban with more than half living in urban areas today and another 2.5 billion expected by 2050

With nearly 38 million people, Tokyo tops UN’s ranking of most populous cities followed by Delhi, Shanghai, Mexico City, São Paulo and Mumbai

New York, 10 July—Today, 54 per cent of the world’s population lives in urban areas, a proportion that is expected to increase to 66 per cent by 2050. Projections show that urbanization combined with the overall growth of the world’s population could add another 2.5 billion people to urban populations by 2050, with close to 90 percent of the increase concentrated in Asia and Africa, according to a new United Nations report launched today.

The 2014 revision of the World Urbanization Prospects produced by the UN Population Division of the Department of Economic and Social Affairs notes that the largest urban growth will take place in India, China and Nigeria. These three countries will account for 37 per cent of the projected growth of the world’s urban population between 2014 and 2050. By 2050, India is projected to add 404 million urban dwellers, China 292 million and Nigeria 212 million.

The urban population of the world has grown rapidly from 746 million in 1950 to 3.9 billion in 2014. Asia, despite its lower level of urbanization, is home to 53 per cent of the world’s urban population, followed by Europe with 14 per cent and Latin America and the Caribbean with 13 per cent.

The world’s urban population is expected to surpass six billion by 2045. Much of the expected urban growth will take place in countries of the developing regions, particularly Africa. As a result, these countries will face numerous challenges in meeting the needs of their growing urban populations, including for housing, infrastructure, transportation, energy and employment, as well as for basic services such as education and health care.

“Managing urban areas has become one of the most important development challenges of the 21^st century. Our success or failure in building sustainable cities will be a major factor in the success of the post-2015 UN development agenda,” said John Wilmoth, Director of the Population Division in the UN’s Department of Economic and Social Affairs.
