There’s some chronological complication somewhere in the list, but this is roughly the order:
Columbus, OH
Syracuse, NY
Chillicothe, OH
Springfield, OH
Aberystwyth, Wales

…so, 8.

Danville, KY
Laurinburg, NC
Greenville, NC
Bloomington, IN
Pine, CO
Denver, CO
Bremerton, WA
Springfield, Illinois

Kashiwazaki, Niigata, Japan
Joplin, Missouri (again)
Bourbon, Missouri
Loami, Illinois
Springfield, Illinois (again)
I have a problem with the term “city”, since some of the places that I’ve lived in have been urban areas but not (strictly speaking) cities. So, here we go:
North Sydney, NSW – born there, but it was a municipality then, and not a city.
Warringah Shire, NSW – urban, but not a city.
Leicester, England
Leeds, England
Newcastle, NSW*
St Pancras, England (metropolitan borough within the county of Greater London)
Randwick, NSW (municipality)
Canberra, ACT (called a city, but not incorporated as a city separate from the rest of the ACT)
Columbus, Ohio
Washington, DC (which I’m counting because it was the address I got my social security card at).
- which I’ve lived in on several separate periods, so I regard it as (in a sense) my home town.
I haven’t lived in as many “cities” as I have “towns”, so I’ll leave some of these generic (anti-stalking, donchaknow).
Niagara Falls, NY
Small Town, CA (near Sacramento)
Back to Niagara.
Small Town in northern Maine.
Orono, ME (college).
Another small town in northern Maine (more college)
Portland, ME and 6 different suburbs (and/or nearby towns) thereof
San Francisco, CA
Oakland, CA
And back to Maine, but no new towns/cities.
Counting up … 14 different cities/towns, and probably close to 40 seperate residences (I went through a stretch where I moved to a new apartment every year – don’t ask me why).
I’ve lived in some pretty small towns, so once you get below say 500 population I’ll just list the nearest large community within walking distance:
Dunkirk, NY (including the several years spent at a small community on the shores of Lake Erie where, despite the fact I don’t like the beach or swimming I didn’t know how good a location I was in.)
Fredonia, NY (including the several years spent on a farm on the outskirts which was techinically in another township, the closest community with a crossroads and a business being Laona, the home of american Spiritualism.)
Sarasota, FL.
Ithaca, NY (Cornell.)
Orlando (UCF)
Sarasota again (couldn’t get a job.)
Palm Bay, FL (got a job.)
Orlando, again (got another job.)
Condo/apartment in both Palm Bay and Orlando, now (got yet another job.)
Cuba City, WI
San Antonio, TX
Biloxi, MS
Panama City, FL
Cedar Grove, FL
Aviano, Italy
Parker, Fl
Platteville WI
Greenville, WI
Unless I’m forgetting something, It looks like 9.
Hmm…I’ve never counted them all up.
Saginaw, MI
New Baltimore, MI
Anchorville, MI
Chesaning, MI
Minneapolis, MN
Columbus, OH
Nashville, TN
Yelm, WA
Brentwood, TN
Smyrna, TN
Readyville, TN
StG
Lennoxville Québec (now Sherbrooke)
Kippenheimweiler, Germany
Rock Forest Québec (now Sherbrooke)
Guelph, Ontario
Hamilton, Ontario
Montreal, Québec
5 or 6, depending on how you count it, since at the time Lennoxville and Rock Forest were separate municipalities, but have now been absorbed into Sherbrooke.
And just for fun: 9 different homes
I’ve never lived in a city, but I lived in the town of Gordonsville, VA during most of my teen years. It’s most notable feature is a traffic circle, unusual for Virginia.
San Francisco.
Apparently I lived in Pacifica at some point, but as it was apparently before I could retain a memory, I don’t count it.
Rochester, NY
La Cañada, CA
Berkeley, CA
Los Angeles, CA
Van Nuys, CA
San Jose, CA
Sausalito, CA
San Francisco, CA
Mill Valley, CA
Huh - only 9. I thought I’d lived in more, but I guess I just moved around inside cities.
