9.6 billion by 2050

The United Nations has revised its population estimates for 2050:

The current world population of 7.2 billion is projected to increase by 1 million over the next 12 years and reach 9.6 billion by 2050, according to a United Nations report launched today, which points out that growth will be mainly in developing countries, with more than half in Africa.

Much of that growth will happen in cities in Africa, many of which are ill-prepared for the influx of people.
