"Pegged at more than 10 lakh in a city of about 50 lakh people, there is one migrant from UP or Bihar for every five Punjabi. ...
Like Ranjit Kumar, who calls himself Ranjit Singh these days, nearly 11% of people from Bihar and UP use Punjabi surnames. The 25-year-old, who came from Bihar to Sainian Bahurian village in Gurdaspur district to work in the farm of Mann Singh, is as much Punjabi as anybody around him.
Sukhram, too, is no exception. He came to Sunam in Sangrur from Purnea in Bihar, some 15 years ago to work for Mohinderpal Singh Dhindsa.
Now, with a beard and kara on his wrist, he is indistinguishable from the people around him in this nondescript town."
