What are the American versions of British cities?
Here are some of my ideas
London - NYC, for obvious reasons.
Birmingham - Chicago. Chicago is in the midwest; Birmingham is in the West Midlands. Both large cities; both also have something of a reputation for crime.
Bristol - Portland. Both west coast cities; both with large anarchist/far left movements with opposition to the police, both with large amounts of drug users.
Brighton - San Francisco. Both the gay capitals of their respective countries.
Leeds - Dallas. Don't really know much about either city but they're both relatively large and both cities have large motorway networks.
Manchester - Atlanta. Again both large cities, both also major transit points in their own countries
Sheffield - Detroit. Post industrial rust belt with lots of crime/deprivation in parts.
Newcastle - Cleveland? Again sort of rust belt area, maybe wrong though. There is also a Cleveland in the Northeast of England.
Glasgow - Houston. Both huge, sprawling metropolises with ridiculously large motorways/highways. Glasgow is probably the most "American" of all the cities here because of its grid road layout. It's also often used as a substitute for New York when filming movies.
Liverpool - New Orleans. Both large port cities, both with their own unique culture. Both cities are predominantly Catholic enclaves within historically Protestant countries. New Orleans has a unique creole culture, Liverpool has a unique culture/dialect of its own made up of lots of different immigrant groups almost forming its own ethnic mix (irish, welsh, scottish ,norwegian/german, chinese etc)
Belfast - Birmingham (Alabama). Both have histories of bombings (lots of bombings in birminghams in the 50s and 60s). Both have issues with conflict (racism/segregation in alabama, the troubles in belfast/northern ireland).
As a general rule of thumb, I would say the north of england particuarly the northwest, as well as scotland and northern ireland are comparable to the American south, whereas the south/east of england are comparable to the American north, and the west coast (california etc).
