The world’s population is becoming increasingly urban. Sometime in 2007 is the turning point when city dwellers formed the majority of the global population for the first time in history. Today, the trend toward urbanisation continues: as of 2014, about 54% of the world’s population lives in cities – and it expects to reach 66% by 2050. Migration forms a significant, and often controversial, part of this urban population growth.
