Over the past three decades, more than half of the world's population lives in cities. In 1999, 47 percent of the world's population (2.9 billion people) lived in cities. By 2030, according to UN projects, this ratio will reach 60% and make up 4.9 billion people. About 95 percent of this major urban growth is occurring in less developed countries.
