(I)Cities are economically vibrant spaces around the world and drawing a large number of rural migrants looking for better prospects. This is a sustained trend, particularly in developing countries now a day.
(II) A fresh look at urban governance is necessary as migration from rural areas picks up pace. (III) The rate of migration has shown a consecutive decline in the last three Censuses.
