In 2011, 22.7% of the population in the Salford USD (Urban Subdivision) were non-white British compared with 15.6% for the surrounding borough. The USD had a slightly larger percentage of Asian and black people. Salford has become a lot more ethnically diverse since the previous census, probably due to the relocation of many BBC establishments from London between 2011 and 2012. This has created many jobs and encouraged migration to the area, which was previously very deprived since the loss of many traditional industries in the 20th century.
