Distribution of urban population and its growth rate is very uneven in the world. Describe.

Solution
Distribution of urban population is very uneven in the world:
(i) While N. America with almost 80% of its urban population being urban is the most urbanised continent. Africa has only 20% of its population urban and Asia is 35-40% urban. The rate of urbanisation has also increased rapidly in recent years. In 1950 only 16% of the world population was urban which rose to 46.7% by 2000.

(ii) An important point of world urbanisation is the great difference in the emerging trends between the developed and the developing regions of the world. In 1950, 20 of the world’s 30 largest metropolitan cities were located in developed countries, 11 in Europe and 6 in North America.

(iii) From a region of villages, Asia is fast becoming a region of cities and towns. Its urban population rose nearly five fold between 1950 and 1995 to 1.2 billion. There are 16 of the 30 largest cities of the world, in Asia. 45% of the world’s urban population lives in Asia. Almost all developing countries, are experiencing high rates of urbanisation. Karachi, in Pakistan, with 1.1 million population in 1950 is estimated to have 20.6 million in 2015. Likewise Cairo, Mumbai, Sao Paulo. Lagos etc. are projected to have populations in excess of 20 million by 2015.
