Mumbai: The first draft of the National Register of Citizens (NCR) which was published on July 30, 2018, updated for the first time since 1951, left out over 40 lakh people in Assam.

The final list that was released on August 31, 2019 excluded over 19 lakh people. The government has given a window of 10 months to those missing from the final NRC to prove their citizenship before being sent to detention centres.

The register is meant to be a definitive list of Indian citizens in Assam, separating them from undocumented migrants, mostly those believed to be from Bangladesh.
