The Importance Of Urbanization

Recently, global attention has been drawn to the fact that world’s population has been urbanized, triggering them to move from a rural area to an urban society. Urbanization is defined as the process by which rural areas become developed and urbanized as a result of economic development and industrialization (Naab et al., 2013). In this case, urbanization will cause the shift of a number of population from a rural area to an urban area, which leads to an increment in the number of urban society in that particular area. According to United Nations (2008), the number of urban population will be doubled and increases from 6.7 billion to 9.2 billion between 2007 and 2050. In short, global urbanization causes a rise in the number of population in developed countries from 63% to 85% (GHEC, 2007). Available statistics show that current world’s population has reached 7 billion and will keep increasing, where more than 50% of global population reside in urban areas (Wu, 2014).

As a matter of fact, urbanization occurs mainly because of the expansion of city boundary which engulfs the rural area. This will result in the increment of interaction of residents,

Not to mention, residents in many cities of developed countries spend 90 percent of their incomes on foods. Hence, it implies that urban population depends on their incomes in order to afford a healthy diet; and thus employment opportunities. However, in rapid urbanization issues, the employment opportunities might be not sufficiently available due to overcrowding in that particular urban area. According to Lancet (2013), evidence proves that there is a causal relationship between income and infant mortality rate. Therefore, there would be some challenges for the vulnerable financial groups in urban populations to consume such highly cost ‘safe
