The earth is witnessing an urban
revolution, as people worldwide crowd into towns and cities. In 1800 only
five percent of the world’s population were urban dwellers; now the proportion
has risen to more than forty-five percent, and by the year 2010 more people will
live in towns and cities than in the countryside. Humanity will, for the first
time, have become a predominantly urban species. Though the world is getting more crowded by the day, absolute numbers of population are less important than where people concentrate and whether these areas can cope with them. Even densities, however, tell us nothing about the quality of the infrastructure’-roads, housing and job creation, for example--or the availability of crucial services.
