New Delhi: Smart cities will be selected through a bottom-up rather than top-down approach, where the decision would be made by the citizens and municipalities concerned, Prime Minister Narendra Modi said on Thursday.

"For the first time such an approach is being taken, where neither the centre nor states will decide. The decision to become a smart city will be taken by the citizens themselves, by the municipalities," Modi said launching the three missions on Smart Cities, the Atal Mission for Rejuvenation and Urban Transformation and Housing for All.
