A city and/or metropolitan area with a very high population or average density. A [megacity] is generally considered to be an urban [agglomeration] with a population of at least 10 million, though the United Nations defines it as a metro area that is home to at least 5 million people living in an area of consistent urban-level density. Most of the worlds megacities are in the developing world — particularly sub-Saharan Africa and South and East Asia — which is rapidly [urbanizing] to the same high percentage that is seen in the United States, Latin America, and Western Europe. However, these cities are generally built with little in the way of construction regulation or public infrastructure. By the year 2030, it is estimated that more than 60 percent of the worlds population will be urban.
