Global: The humanitarian iImpact of urbanisation - Overview

Somewhere, some time this year, a baby will be born on the 25th floor of a city hospital or the dirt floor of a dark slum shack; a first-year college graduate will rent a cramped apartment in lower Manhattan, and a family of five will finally concede their plot of farm land to an encroaching desert or sea, and turn towards Jakarta or La Paz or Lagos in search of a new livelihood and a new home. The arrival of this family or graduate or baby will tip the world’s demographic scale and, for the first time in history, more than half the human population will live in cities.
