At what population do you jump from the status of being a small town to a big town? Is Sedalia a small, big town, or a small city?

I guess it depends on where you were raised. I came from a town with a population under 4,000. Of course there were smaller towns around that had lesser populations, and there was a few that were even bigger. When I moved to Sedalia in 1977, I thought I'd moved to a big town.

According to information I gathered on population.us, the number was at 22,847 in 1970 and in 1980 it dropped to 20, 927. So most likely the population in 1977 was around 21,000.

According to the Urban Dictionary:

Big City: 300,000+ people within city limits
City: 100,000-300,000 citizens within limits
Small City: 20,000-100,000 citizens within limits
Big Town: 7,000-20,000 citizens within limits
Town: 800-7,000 citizens within limits
Small Town: 200-800 citizens within limits
Village: 50-200 citizens within limits
Hamlet: Community with less than 50 members.

So according to these numbers, Sedalia is considered a small city.
