Type 'easy' or 'hard' to begin the quiz. Easy is a 5-degree grid, hard is a 2.5-degree grid. Then, try to name the LARGEST city in each grid square which fits the category label for each square. To name a city, you must first click on the grid square to make it have a GREEN border. Then, type in the city answer for that square followed by a '.' (a period). You are given a score from 0 to 100 based on your answer's population compared to the largest city accepted in that square (100 being you named the largest city).
LETTER: means the city starts with that letter.
NUMBER RANGE: (such as 2-5, 10+) means the city contains that many letters (excluding spaces and special characters).
POPULATION RANGE: (such as 50-100K) means the city has that range for its population.
2+ WORDS means the city name has 2 or more words (words denoted by a space or hyphen).
AK and HI are NOT included in this quiz as they often have grid squares with only one answer for this quiz.
At the end of the quiz the largest population missed answer will show in each unanswered square, and for those answered the largest city will be listed if you didn't answer it.

hempstead doesnt count?
It’s a township – those typically are not counted in my city quizzes.
I’m confused why Metairie is included. Everything I searched for said it was not incorporated during the time period it’s included in. I think I found your source, and I don’t know why they include that either.
I think maybe the census included unincorporated places back then? Not sure.
Holy crap. The city at #99 in 1950 jumped SEVENTY (70!!!) spots in 1960.
I wonder if any city has come even close to that 70 position jump between 1950 and 1960…
Oh wow, that really is something. I had no idea that 1950 #99 was such a small city only 70 years ago…
Interesting find, Ovamiat!
According to Wikipedia, in 1958 the city “doubled in size” due to annexation, not sure whether the doubling refers to population or land area or both. There was certainly plenty of actual population growth, but some of it is just changing boundaries.
It got bigger because of advances in AC during the 1950s
Hey Darin, Sherburne, MA is actually the same town as Nantucket (they changed the name in 1795) so you might consider letting “Nantucket” count, unless you think people should know about the town’s archaic name to get the point.
will add as alternate.
Great, seems to be working!
Ah, I was very confused what happened to sherborn Mass was included when its still less than 5k now, but that makes much more sense
