Tiruvottriyur has industrial units, trading activity, and nearby fishing hamlets.

The area is easily accessible by Metropolitan Transport Corporation (MTC) buses from across the city and has a bus terminus.

Along with Avadi, Ambattur, Sembium, and Ennore, Tiruvottiyur is part of the "auto belt" in the city's industrial north and west regions that developed when the automobile industry developed in Madras during the early post-World War II years.

[1] In April 2018, the state government transferred Tiruvottiyur to an expanded Chennai district.

Sea encroachment was a major problem for fishermen before the building of Groynes started in 2004.

This was chiefly because of numerous industrial units, mills, power plants, refineries, fishing harbours, and docks.

[4] According to the 2011 census, Tiruvottiyur had a population of 249,446, with a ratio of 991 females for every 1,000 males, much higher than the national average of 929.

Due to a delayed road-widening project, traffic congestion is common in Theradi during peak hours.

[vague] The blue line of Chennai Metro is extended up to Wimco Nagar in Thiruvottriyur, and is up and running.
