Where do you get this information from? Can you provide evidence to support this?
According to the 2001 census there are almost 200,000 people in the West Midlands whos' families have their origin in India as opposed to just over 100,000 in the Northwest. Remember that Leicester and the East Midlands also has a large population of people whos' families are from India too (143,000) and Leicester/Nottingham/Derby are easily accessible from Birmingham Airport.

Indeed Birmingham and the West Midlands has more people whos' families originated outside the UK than any other city outside London with the exception of the Chinese community where Birmingham and Manchester are equal second and Italian community which is relatively low in the West Midlands.
