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.
ORBIS is powered by ESPAS, the European Strategy and Policy Analysis System, a unique inter-institutional project aimed at strengthening the EU's efforts in the crucial area of forward planning. ESPAS brings together the European Commission, the European Parliament, the Secretariat General of the Council of the European Union and the European External Action Service to strengthen the Union's collective administrative capacity to identify and analyse the key trends and challenges, and the resulting policy choices, which are likely to confront Europe and the wider world in the decades ahead.
