According to the state-run Wildlife Institute of India, there are an estimated 3,600 tigers in India. Four years ago there were only 1,411 – the lowest figure ever.
According to the government, the increased population is due to efforts to preserve the tigers and their habitat.
India is believed to have had a tiger population of around 40,000 at the time of independence from Britain in 1947.
Since then, deforestation, poaching and human settlement in the tigers’ habitats have led to a sharp decline in the population.
Tigers once roamed central, eastern and southern Asia, but have lost nearly 95 percent of their historic range over the past century.
"Continued efforts to protect tiger habitats are critical to securing the future of India’s tigers and their ecosystems for generations to come," the government writes in a press release.
India is currently home to 75 percent of the world’s tigers.
