More than half of the world’s population lives in cities which is even growing rapidly and some of the cities are astounding in the growth metric. In 2014, about 53% of the world’s population resided in towns and cities. However, levels of urbanization still vary from country to country. The urban population has been increasing consistently in every corner of the world. A surprising fact is, in 1950 the world’s population was 2.5 billion and in last 70 years it has become 7.2 billion. The number is expected to increase another half a billion by 2050. About 50% of the world’s urban dwellers live in a relatively small settlement, while about 13% live in mega-cities.
