I want to know the answer to the following question:
How many buddhists are in Asia?
All the background I'm provided with is that "According to Johnson and Grim (2013), Buddhism has grown from a total of 138 million adherents in 1910, of which 137 million were in Asia, to 495 million in 2010, of which 487 million are in Asia.". Is that enough to answer the question?
