It attracts many people from different parts of the city and its suburbs, owing to its location
and transportation links. T.Nagar has the highest commercial catchment population when
compared with other commercial centers of the city like Adyar, Nungambakkam,

have given way to multi storey shopping malls, but with little change in the infrastructure.
