The West Bengal Official Language (Second Amendment) Bill, 2012, included Hindi, Santhali, Odiya and Punjabi as official languages if it is spoken by a population exceeding 10 per cent of the whole in a particular block or sub-division or a district. Subsequently, Kamtapuri, Rajbanshi and Kurmali were also included in the list of minority languages by the West Bengal Official Language (Second Amendment) Bill, 2018. However, as of 2020, there is no official / other reliable information about the areas covered. Census 2011 provides language data only at the district and above level.
