I run a geography quiz game that challenges you to name as many cities1 in the United States as you can. In this post, co-written with my friend Sasha Trubetskoy, we've analyzed 49,468 plays of the quiz2 to answer questions like "How many cities can the average person name", "What are the best-known cities in America", and more.
The median player named 104 cities. 75% of players named at least 47 cities, and 25% of players named 207 cities or more. Here's every tenth percentile:
You should take these numbers with a grain of salt, because some players undoubtedly "cheated" and because not everyone was genuinely trying to name as many cities as they could. Also note that sessions with fewer than 10 cities named have been excluded from this analysis.
For real competitors, here's every percentile above the 89th:
I've seen some plays with more than 20,000 cities named, which defy credulity, so the very highest percentiles are likely inflated a little, but I don't doubt that some people really can name more than 1,000 cities from memory.
Here are the twenty best-known cities in the United States, by the percentage of players that named them:
|1||New York, NY||90.8%|
|2||Los Angeles, CA||88.3%|
|5||Las Vegas, NV||82.4%|
|6||San Francisco, CA||82.2%|
|14||San Diego, CA||74.3%|
|16||New Orleans, LA||73.8%|
Little surprise that New York City, Los Angeles and Chicago top the list. Sixteen of these twenty are also among the twenty most populous metropolitan areas in the United States,3 while Portland (25th), Las Vegas (28th), Austin (29th) and New Orleans (45th) fall outside. The four top-twenty metro areas that don't make the best-known list are the Inland Empire (13th), Minneapolis (16th), Tampa (18th), and St. Louis (20th).4
The best-known cities with at least 15 letters in their name:
|1||Colorado Springs, CO||36.1%|
|3||Huntington Beach, CA||9.6%|
|4||Truth or Consequences, NM||6.4%|
|5||Saratoga Springs, NY||4.9%|
|6||Rancho Cucamonga, CA||4.9%|
|7||International Falls, MN||4.5%|
|8||South San Francisco, CA||4.1%|
|9||Steamboat Springs, CO||3.5%|
|10||Panama City Beach, FL||3.3%|
The best-known city for each letter of the alphabet:
|E||El Paso, TX||54.0%|
|F||Fort Worth, TX||48.2%|
|G||Green Bay, WI||37.6%|
|K||Kansas City, MO||66.5%|
|L||Los Angeles, CA||88.3%|
|N||New York, NY||90.8%|
|S||San Francisco, CA||82.2%|
|V||Virginia Beach, VA||26.1%|
Perhaps more interesting than the best-known cities is the list of cities that are surprisingly well-known relative to their population. Using the quiz results, my friend Sasha Trubetskoy devised a piecewise linear regression that estimates the number of times a city is expected to be named, based on its population. By computing the ratio between a city's actual and expected popularity using this function, we can see how surprising the city's popularity is.
Here are the twenty most surprisingly well-known cities:
|9||Palm Beach, FL||8,348||12.3%||0.2%|
|17||Key West, FL||24,649||24.4%||0.6%|
|20||Truth or Consequences, NM||6,475||6.4%||0.2%|
The list includes some cities that are legitimately well known, including state capitals (Montpelier, Pierre, Juneau, Helena, Augusta, Dover) and others (Aspen, Gettysburg, Palm Beach, Moab, Malibu, Key West, Taos, Truth or Consequences), as well as some cities sharing a name with a much larger counterpart that were likely guessed randomly or by mistake (London, Berlin, Brooklyn, Paris, Toronto). I assume that people got "Adams, MA" just by guessing that Adams would be the name of some city in the U.S.
All the surprisingly popular cities in the table above are quite small. Here's what the top twenty looks like if we limit it to cities with at least 50,000 people:
|2||Carson City, NV||55,274||32.2%||1.9%|
|3||Santa Fe, NM||67,947||43.1%||2.7%|
|12||Iowa City, IA||67,862||22.3%||2.7%|
|17||Niagara Falls, NY||50,193||11.5%||1.6%|
|18||Santa Cruz, CA||59,946||15.2%||2.2%|
|19||Green Bay, WI||104,057||37.6%||5.5%|
|20||Daytona Beach, FL||61,005||15.3%||2.2%|
Again, we have many state capitals, but only one city with a famous name this time (Manhattan). Other cities are famous for various reasons: for example, Green Bay is home to a professional football team, and Scranton was the setting of a popular American sitcom (not to mention the birthplace of Joe Biden).
On the flip side of the coin, here are the twenty most surprisingly obscure:5
|1||Sunrise Manor, NV||189,372||0.6%||14.7%|
|3||South Whittier, CA||57,156||0.1%||2.0%|
|4||Town 'n' Country, FL||78,442||0.2%||3.4%|
|5||Kendale Lakes, FL||56,148||0.1%||1.9%|
|7||Casas Adobes, AZ||66,795||0.2%||2.6%|
|9||Country Club, FL||47,105||0.1%||1.4%|
|10||Aspen Hill, MD||48,759||0.1%||1.5%|
|12||North Highlands, CA||42,694||0.1%||1.2%|
|13||San Tan Valley, AZ||81,321||0.3%||3.6%|
|14||Pine Hills, FL||60,076||0.2%||2.2%|
|15||Spring Valley, NV||178,395||1.3%||13.3%|
|16||Lehigh Acres, FL||86,784||0.4%||4.0%|
|18||Mission Bend, TX||36,501||0.1%||0.9%|
|20||Lake Ridge, VA||41,058||0.1%||1.1%|
Every city here is a census-designated place, a category created by the Census Bureau for localities that are not legally incorporated, which tend to be lesser-known than incorporated municipalities. Furthermore, all of them are suburbs in the Sun Belt, with a propensity towards smaller metro areas (Sacramento, Orlando). The Sun Belt is the fastest-growing region in the United States, and many of these cities were evidently founded too recently to have left much of an imprint on the popular imagination.
Finally, here are the most surprisingly obscure cities with at least 200,000 inhabitants:
|3||Chula Vista, CA||243,916||7.5%||22.3%|
|6||Santa Ana, CA||324,528||13.3%||34.9%|
|8||North Las Vegas, NV||216,961||7.6%||18.4%|
Once again, they are all suburbs and satellite cities in the Sun Belt.
Here are the ten most forgotten state capitals:
|2||Jefferson City, MO||15.3%|
They are all either the capitals of small states (Concord, Augusta, Charleston, Pierre, Montpelier), the capitals of states with much larger cities (Jefferson City, Springfield, Annapolis, Harrisburg), or both (Frankfort).
And finally, here are the most forgotten states, by percentage of players who named at least one city in the state:
West Virginia, the most forgotten state, likely suffers from the fact that its capital and largest city, Charleston, is also the name of a larger city in South Carolina. Connecticut is the most populous state on the list, with 3.5 million people. Alaska and North Dakota are the least populous states not on the list, probably because Anchorage and Fargo are fairly well-known.
Finally, a few miscellaneous interesting stats:
Here and throughout I use "cities" as a shorthand to refer to populated places of any size.↩
49,468 is the number of sessions with at least 10 cities that were saved up to October 31, 2020. Note that sessions that were not saved, whether because they were still in progress or because user simply elected not to save them, were not included.↩
I'm playing a bit fast and loose with the terminology here. Technically, metropolitan areas are defined by multiple cities that form the urban core, e.g. New York, Newark and Jersey City for the New York metro area. As it happened, no two cities in the top twenty were in the same metro area. Although the quiz itself uses city-proper populations as reported by the 2010 census, the 2019 metro area populations are more appropriate for comparison as they give a better idea of what cities we would expect to be the best-known.↩
A number of townships in New Jersey and Pennsylvania were added to the database of cities a while after the quiz was initially published; these have been excluded from the table because their popularities are artificially low.↩
