How many sunni barelvi are in the world?

Estimating the number of Sunni Barelvi followers worldwide is challenging due to varying definitions and the lack of comprehensive demographic data. However, it is estimated that there are tens of millions of Barelvi Muslims, primarily concentrated in South Asia, particularly in Pakistan and India. Some estimates suggest that their numbers could range from 20 to 30 million, but precise figures are hard to determine. The Barelvi movement emphasizes a particular interpretation of Sunni Islam and is known for its devotional practices.
