If you read a lot of articles about cities and urbanism, you're probably familiar with the words "half of the world's population now lives in cities." For a number of years, these words have been frequently used in the opening sentences of articles, hoping to convince readers in just a few seconds of the importance of the subject at hand. In fact, according to the World Health Organization these words are no longer even true: in 2014 the urban portion of the world's population has already reached 54%. In other words, every nine months the world adds enough new urbanites to fill a city the size of Tokyo, with an increase of nearly 300 million new urban dwellers since we reached the tipping-point in 2008.
The rise of cities has been so dramatic that UN Habitat has declared today, October 31st 2014, as the first annual World Cities Day.
Of course, all of this means that there has never been a better time to be an urbanist than right now. Or does it?
