"...economically depressed and druggy"
Over the decades we've lived in several different cities; London, Bristol, Manchester, Leeds, Harlow, Colchester, Peterborough. All are different.
Is Peterborough "economically depressed"? No. But there again, are there masses of high paying jobs in Peterborough? Here the answer is also, No.
Peterborough is much more a city of manufacturing and distribution centres rather than high tech industries. According to the ONS, the median pay for a full time worker in Peterborough is about 20% lower than in Cambridge (but there again, house prices are also an awful lot cheaper).
Large employers include the likes of Perkins Engines and also Amazon, Ikea and Lidl amongst others all employ lots of people in local distribution centres.
It has four Aldis but also has the 5th largest Waitrose store in the country (about the same size as the Waitrose near Kings Cross).
Economically depressed? No. A rather different profile to Cambridge? Yes. Peterborough doesn't really have any high-end shops, if that's important then Cambridge is the place to go shopping.
"...and druggy"
No more or less than any other city I've ever lived in. Well, actually, quite a bit less than some of the larger cities we've lived in, in the past.
