Islam and Christianity in India. Increasing or declining?

How do you guys view this? I get that many Western countries(in Europe and NA) are starting to see declines or younger generations not identify as religious.

In ME, numbers are skewed due to dictatorship regimes.

What about In India? How is the situation there? Could anyone say if either Islam or Christianity is on its last legs there as well or if it will still take time?

What about Afghanistan, Pakistan and Bangladesh as well?
