Are there any diverse market towns?

Just been watching Escape to the Perfect Town on BBC which was quite interesting. A London couple with 2 kids looking to move to Yorkshire to get more fur their £250k than a 1-bed flat. As someone in (almost) their initial position, I can see lots of benefits to finding a lovely market town somewhere and moving outside London to grow our family. But I can't think of anywhere that isn't 99% white. Are there any ethnically diverse market towns in England? I suspect the answer is no and cities like Bristol or Brighton are a better choice.
Are there any people of colour on here who have made the move to a market town?

I live in a Derbyshire market town that is very white working class. I sadly can't think of any ethically diverse market towns in Derbyshire or Nottinghamshire.

Peterborough?

OP, if you choose to stay in London for diversity reasons, don’t feel hard done by. Just move to somewhere nice on the edge of London. You’ll still get the diversity, coutryside on the doorstep, general leafiness, weekly/monthly markets, low crime, fab schools etc It won’t be as pretty as a market town but at least you’ll have an easy commute to work and more amenities.
