The predominant religious community in the area are Hindus, especially Nairs which constitute 54 per of total population, followed by Muslims, and then by Christians.^{[citation needed]} This area of Travancore kingdom had been historically dominated by artisan caste people, who worked in the quarries to build the bricks, stones and masonry for the temples and palaces of Travancore kingdom in the capital city. with the development of the city, vattiyoorkavu became one of the most sought after residential areas in the city mostly for middle-class people due to the availability of most city facilities in a comparatively green and clean locality at comparatively affordable rates. In recent years, land prices have increased and several flats and apartment complexes have come up in the region and more upmarket residential areas have been created. This can be mostly attributed to the presence of large number of excellent educational institutions including Saraswathi Vidyalaya and Bharatiya Vidya Bhavan. As a result the junction and surrounding areas are now affected by regular traffic blocks. The next phase of the TRIP,trivandrum road improvement project is centred on vattiyoorkavu and aims to develop the junction as well as extend the four lane road with carriageways from sasthamangalam to peroorkada via vattiyoorkavu.
