In 2011, there were 468 Urban Agglomerations/Towns, an 18.78% increased from the corresponding number (394) in 2001; a majority of 70% (or) 264.9 million of the total urban population lives in these Agglomerations and towns. The census notes "The proportion of this population has increased considerably over the last census". In the remaining classes of towns the growth has been minimal.
