Thiruvalla, alternately spelled Tiruvalla, is a Municipality in Kerala and also the headquarters of the Taluk of same name located in Pathanamthitta district in the State of Kerala, India. The town is spread over an area of 27.94 km . It lies on the banks of the river Pamba and river Manimala, and is a land-locked region surrounded by irrigating streams and rivers. Thiruvalla is regarded as the "Land of Non resident Indians ". Due to the increasing migration of young people, it is now battling a decline in its population. The age group above 60 makes up almost 54% of the town's population. Also due to declining fertility levels in Thiruvalla (almost 0.7), many schools are being forced to shut down due to the lack of children. Thiruvalla is also famous for the dance of Kathakali, which is hosted in the Sreevallabha temple almost every day in a year.
