Abstract in English:
We live in a world which is becoming increasingly urban, where more and more people are moving to cities. Over 54 per cent of people across the globe were living in urban areas in 2014 (UN DESA, 2014).1 The current urban population of 3.9 billion is expected to grow in the next few decades to some 6.4 billion by 2050 (ibid.). It is estimated that three million people around the world are moving to cities every week (UN-Habitat, 2009). Migration is driving much of the increase in urbanization, making cities much more diverse places in which to live.
Nearly one in five of the world foreign-born population resides in established global gateway cities (Çağlar, 2014). In many of these cities such as Sydney, London and New York, migrants represent over a third of the population and, in some cities such as Brussels and Dubai, migrants account for more than half of the population.
