World's slums grow despite rapid economy growth - U.N.

RIO DE JANEIRO (Reuters) - Almost a quarter of a billion people moved out of slum conditions in the past decade, driven by rapid economic growth in emerging giants India and China, but the number of people living in them continues to rise, the United Nations housing agency said on Friday.

The number of people living in shantytowns increased by 55 million to 827.6 million as population growth and migration from the countryside outstripped the effect of upward mobility in cities, the U.N.'s biennial report on cities found.
