Huh, only 14. Seems low to me, probably 'cause I’ve lived in a couple of those places a few different times.
I counted 21… In 5 countries.
A one time, sort-of okie? You don’t see that too often.
My list…
Oklahoma City, OK (4 years)
Shattuck, OK (14)
Stillwater, OK (1)
Pratville, OK (4)
Tulsa, OK (3)
Bedford, TX (6)
Roswell, GA (18 and counting)
Do places you lived as a child count…?
Chronoligically (there are repeats, but in the order of first time in each)
Cambridge, MA (if being a baby there counts)
Tel Aviv, Israel (actually last chronlogically if living with parents doesn’t count – done both)
Newton, MA
Rochester, NY
Haifa, Israel
Bnei Braq (technically, in reality across the street from Ramat Gan) Israel
So – 5 or maybe 6.
Been living continuously in Tel Aviv for the past 23 years (currently on my third apartment – been here for 21 years!)
7, I guess, less if I just say “Silicon Valley”.
LA, CA
Davis, CA
Phoenix, AZ
San Jose. CA
Palo Alto, CA
Cupertino, CA
Santa Barbara, CA
Technically, I’ve only actually lived in four cities –
Cambridge MA
Rochester, NY
Binghamton, NY
Salt Lake City, UT
But I’ve lived in the suburbs, very close to
New York City
Boston MA
<List>
Austin, Texas
</List>
I’m more interested in the manner most are posting their lists. They look chronological, offering an additional bit of history.

Solon, OH
Buffalo, NY
Williamsville, NY
Durham, NC
Bar Harbor, ME
Annapolis, MD
Washington, DC
Raleigh, NC

Mine was chronological, and anyone raised as a military kid will know straightaway that I was raised the same, and most will be able to tell what branch my dad was in. 
4 metropolitan areas:
Saskatoon, SK (from birth to undergraduate)
Auburn, AL (family went there for a sabbatical)
Waterloo, ON (grad school)
Toronto, ON (employment)
Counting city names, not zip codes, addresses, or move backs:
Michigan City, IN
Niles, MI
Eastpointe, MI, when it was know as East Detroit
Goshen, IN
West Lafayette, IN
Angola, IN
Bedford, IN
Indianapolis, IN
Hampton, VA
Gatesville, NC
Lexington Park, MD
That makes 11, arguably 10.
Air force brat era:
Dayton, OH
Birmingham, AL (I think… this is before I can remember anything)
Dayton, OH (again)
Albuquerque, NM
Livonia, MI
Oberlin, OH
Post-college vagrancy era:
Cambridge, MA
Boston, MA
Somerville, MA
Stoughton, MA
N. Kingstown, RI
I’ve been moving every summer since the start of college. Sometimes twice, when I had some sort of temporary summer housing. Now, finally, I get to stay in one place for a few years. I’ll probably move again sometime next summer (when my wife finishes her MS) but I’m anchoring us around Providence for the next five years at least.
Los Angeles
Long Beach, CA
Palo Alto, CA
Minneapolis
Chicago
That’s all there’s going to be in the US. If I leave Chicago, I’m going back to LA. As much as I love Philly and would like to give living there a whirl, I’ve lost my patience with picking up and going new places where I don’t know anyone. If I leave the US, I’d go to Costa Rica because it’s awesome and my family’s there. Could potentially go to Italy with spouse. TBD.
I’m just listing cities, not every township I’ve ever lived in (10 total):
Charlotteville, VA
Portsmouth, NH
Moscow, Russia;
Alexandria, VA,
Novosibirsk, Russia,
Pristina, Kosovo,
Baghdad, Iraq
Banda Aceh, Indonesia,
Kabul, Afghanistan,
Washington, DC
10 - Mostly large to mid-sized cities/towns in Washington State and now I’m in the Chicago area.
The people living only in one city are very interesting to me…as are the ones who have lived in numerous countries (military?).
Mine was also in chronological order, and I almost got to start off with Santa Cruz, CA, since I was born there, but my only living address there was the hospital. My mom went straight from the hospital to Wapato, WA to meet back up with my dad, who had moved up a couple weeks before.
