A quick cruise around the net reveals that Coventry has approximately:
132,000 Households
127 Schools of various types
3 major hospitals
93 GP services, many with multiple doctors
A bus station + buses + staff
A railway station + trains + staff
A road network
Utilities networks
Shops, offices, industry = work
Imagine if a new one had to built from scratch every year.
Coincidentally, Coventry is about the same size as net migration to the UK last year.
Go figure.
