East Africa hasn’t urbanized at the same rate as the rest of the world. While over 50 percent of the world’s population now lives in cities, the East African region of Tanzania, Kenya, Uganda, Rwanda, and Burundi - the members of the regional intergovernmental organization East African Community - will only reach an urban population of 31 percent by 2030.
But while the countries as a whole aren't following the urbanization trend at the same pace as other places, some of their biggest cities are among the fastest growing in the world. Of the projected top 20 fastest growing cities in the world from 2010 to 2025, five of them are located in East Africa. Kampala, Uganda is expected to grow by 99.5 percent, followed by Dar es Salaam, Tanzania (85.2 percent), Kigali, Rwanda (79.9 percent), Mombasa, Kenya (79 percent), and Nairobi, Kenya (77.3 percent).
