An estimated 300 million people use this syllabic alphabet, which makes it the 5th most commonly used writing system in the world. It is the sole national script of Bangladesh and one of the official scripts of India, specifically used in the Indian states of West Bengal, Tripura and the Barak Valley of Assam.
