Thanks! Unfortunately, there's just not enough data for me to actually make the quiz using information from around 1803.

Also probably because there probably wasn't more than 10 cities that even existed in the Louisiana Territory in 1803

I wonder if any Canadian cities would've made it. A quick scour on Google Maps seems to say no.

Definitely no 50,000+ population settlement there. From what I can tell, there are few (if any) settlements there with a population of over 1,000.
