The ratio of urban to rural dwellers is that some 55% (approximately 4.2 billion people) reside in urban areas, with this projected to grow to almost 70% by 2050. Nearly 90% of the anticipated growth in urban populations by 2050 is anticipated to occur in Asia and Africacoastal cities on the continent will absorb a great deal of the future urban growth projected.
