How many tigers are alive in total number India today?

I do not have access to real-time information, including constantly changing wildlife population data.

To get the most up-to-date information on the number of tigers in India, I recommend checking the following sources:

* The Wildlife Institute of India (WII): They are a leading research institute specializing in wildlife conservation and conduct regular tiger censuses.

* The National Tiger Conservation Authority (NTCA): This authority oversees tiger conservation efforts in India and publishes reports on tiger populations.

* World Wildlife Fund (WWF): This international conservation organization has a dedicated India branch that focuses on tiger conservation and provides updates on tiger populations.

You can find their websites and reports online.
