Urbanisation, Sustainable Growth and Poverty Reduction in Asia

Almost 3 billion people live in urban areas across the world – equivalent to 48 per cent of the world’s total population. Asia accounts for almost half of these, with an urban population of between 1.3 and 1.5 billion people, accounting for approximately 37 per cent of Asia’s total population (UN-Habitat 2003a; ACHR 2005). These statistics for Asia are perhaps conservative, as different countries define ‘urban centres ’ differently, based upon both population size and other criteria. If either India or China were to redefine their criteria to include some smaller settlements as ‘urban’, then an even greater proportion of Asia’s population would be considered ‘urban’ (Satterthwaite 2005). Asia has a fast growing urban population. The urban population in the region as a whole is projected to grow to 1.8 billion by 2010 (see Figure 1), and as a result Asia is expected to account for a growing proportion of the world’s urban population – just over 50 per cent by 2010 (see Figures 2 and 3). The UN expects this number to increase to between 53 per cent and 55 per cent of the world’s urban population by 2030 (UN-Habitat 2004). In addition to a growing urban population, Asia is also urbanising – that is a growing proportion of its total population live in urban areas (see Figure 4).
