Very good quiz - nice job! The one I find most interesting, and would never have expected, is the city which was the largest in Florida from 1880-1890, given its relative size today.
I scored 53/90 as a non-American. I consider it a fun challenge to finally list cities other than the state capitals. It is not my goal to remember the ones I didn't know :)
This quiz is definitely missing Lexington, Kentucky, which was the largest city in Kentucky in the 2000 census, with a population of 260,512 compared to Louisville's 256,231. (Louisville regained the title of biggest city in Kentucky after it consolidated with Jefferson County in 2004)
another error: Norfolk, Virginia became the biggest city in Virginia in 1960, not 1950. in the 1950 census, Richmond had around 230,000 while Norfolk had around 213,000
Still a great quiz idea though.
Perhaps another 30 seconds? I couldn't finish on mobile.
This list only contains 23 state capitals.
