Now, there are only 3,200 tigers left in the wild around the world.
However, around 100,000 tigers once roamed in the wild a century ago.
The World Wide Fund (WWF) for Nature has revealed it in a report which coincided with the International Tiger Day on Tuesday.
WWF has also offered to assist with the conservation efforts being carried out by the 13 tiger-range countries.
They are India, Bangladesh, Bhutan, China, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Nepal, Russia, Thailand, and Vietnam.
In 2010, these countries committed to securing a doubling of wild tiger population by 2022, says WWF.
The WWF warned that the largest of all the Asian big cats could go extinct in the wild primarily due to poaching and habitat loss.
Poaching is the "most immediate threat to wild tigers" since their parts are used for "traditional medicine, folk remedies, and increasingly as a status symbol among some Asian cultures".
Authorities across Asia seized parts of at least 1,590 tigers, killed for traditional medicines between January 2000 and April 2014, the organisation said, citing figures from the wildlife trade monitoring network Traffic.
In its report, the WWF admitted that it has the statistics of tiger population in the wild in India, Nepal, and Russia.
But it lacks data of Myanmar, Cambodia, China, Indonesia, Laos, Malaysia, and Thailand.
The non-governmental organisation urged those countries to count the number of tigers that exist in the wild with a view to protecting the different subspecies of this big cat.
