The National Capital Region is a much larger entity comprising the entire NCT along with adjoining districts in neighboring states. New Delhi has been selected as one of the hundred Indian cities to be developed as a smart city under Prime Minister of India Narendra Modi's flagship Smart Cities Mission.
