The increase in urban population and the resultant increase in the urban area is called Urbanisation. The increase of population in the urban area takes place by the natural growth of population and also by migrations of rural population to urban areas..Urbanisation brings spatial, temporal and structural changes in the demographic, social, economical, technological and environmental aspects of life in a given society. The accumulation of wealth and availability of job opportunities in the urban centers have resulted into the concentration of human population in limited space. About 29 % of the total world population was recorded as urban population in 1951 and it increased to 54 % in 2011 period. Though urbanisation is an indicator of development, but it is also bitter fact that poverty is growing faster in urban areas in the form of slums. Hence, rapid Urbanisation and Industrialisation without needed urban infrastructure development has resulted in slums and they are residential areas of poor urban people.Keeping the above aspects under consideration an attempt is made in this paper to study pattern of urbanisation and formation distribution of slums in Visakhapatnam city.
