This blog is intended to go along with Population: An Introduction to Concepts and Issues, by John R. Weeks, published by Cengage Learning. The latest edition is the 12th (it came out in 2015), but this blog is meant to complement any edition of the book by showing the way in which demographic issues are regularly in the news.

Urban Population of the World Projected to Increase by 2.5 Billion by Mid-Century

Thanks to Todd Gardner for the link to a report released today from the UN Population Division detailing their new projections of the urban population.
By 2050, two out of every three people are likely to be living in cities or other urban centres, according to a new United Nations report, highlighting the need for more sustainable urban planning and public services.
Most of the increase is expected to be highly-concentrated in just a handful of countries. “Together, India, China and Nigeria will account for 35 per cent of the projected growth of the world’s urban population between 2018 and 2050…It is projected that India will have added 416 million urban dwellers, China 255 million and Nigeria 189 million,” said DESA, announcing the findings on Wednesday.
By 2028, the Indian capital, New Delhi, is projected to become the most populous city on the planet. Currently, Tokyo is the world’s largest, with an agglomeration of 37 million inhabitants, followed by New Delhi (29 million), and Shanghai (26 million). Mexico City and São Paulo, come next; each with around 22 million inhabitants.
As the report suggests, these projections imply a tremendous demand for services to meet the needs of these new (and current) urban residents in a sustainable manner--shelter, food, water, sanitation, education, law enforcement, and of course jobs, many of which will be focused precisely on servicing those needs. This will be simultaneously a challenge and an opportunity, and guarantees that the world will be a different place at mid-century than it is now.
