The information requested falls within the responsibility of the National Statistician, who has been asked to reply.
As National Statistician, I have been asked to reply to your recent question about the number of workers in Preston who have benefited from the national minimum wage (NMW). (169664)
This information is not available at local authority level.
However, the Office for National Statistics (ONS) calculates estimates of the number of jobs paid less than NMW rates for the United Kingdom and Government Office Regions. A guide to measuring low pay and associated articles and data can be found on the National Statistics website at: http://www.statistics.gov.uk/StatBase/Product.asp?vlnk=5837&Pos=1&ColRank=1&Rank=272
