How many cities total does the United States have?

After processing the file with a custom-made script, I find that nine types of places are listed by the Census: borough, Census Designated Place (CDP), city, comunidad, county, municipality, town, urbana, and village. I consider that three of these -- borough, CDP, and county -- do not qualify as self-governing entities. For each of the six remaining types of place, below are the number identified as such.

city 10,016
comunidad 147
municipality 1
town 4,431
urbana 78
village 3,770
------------------
total 18,443

I therefore conclude that there are 18,443 cities, towns, villages, and other such governing groups in the United States. In case you're wondering, the sole place identified as a municipality is Anchorage.

I'm not sure how complete this list is, however, it consists of 262 U.S. "cities" and lists them by population with this intro:

"The following table lists the incorporated places in the United States with a population of more than 100,000 as estimated by the United States Census Bureau on July 1, 2007."

Because there is more than one definition for the word "city," I'll include lists with population counts:
