According to the 2011 census, there were around 24.6 million Muslims living in West Bengal. Nearly 19 million are Bengali Muslims, constituting around 77% of the total Muslim population in the state, and they are mainly concentrated in rural areas. The Urdu-speaking Muslims live mainly in Kolkata and other urban areas of West Bengal.[15] Their percentage in the population has remained largely stable, from 30.3% in 1946 (before partition) to again regaining 30.05% in 2021 as the same status just they have before partition of Bengal in 1947.[3][2][12] Furthermore, the Muslim decadal growth rate has decreased over the last three decades, owing to a fall in fertility rates.[16][17]
