Ethnic groups in Delhi

The original natives of Delhi are those whose ancestors lived in the Yamuna basin, a region which spreads radially from the capital up to a distance of approximately 200 kilometres.

[1] This province was not ethnically homogeneous and large amounts of Hindi-speakers resided in the southeast, now Haryana, eastern side, now West Uttar Pradesh and in Delhi's Yamuna Basin.

Today the migrant population consists largely of Punjabis, Haryanavis, Bengalis and recently, Biharis and Uttar Pradeshis etc.

Linguistic data cannot accurately predict ethnicity: for example, many descendants of the Punjabi Hindu and Sikh refugees who came to Delhi following the partition of India now speak Hindi natively.

Punjabi (including Hindkowan and Saraiki) migrants and refugees, who arrived in hordes from West Punjab and North-West Frontier Province after the Partition, suddenly came to form nearly one-third of the city's population.

[20] South East Delhi's Chittaranjan Park locality hosts the largest Bengali population in the city, the majority of its residents have settled here just after Partition.
