At lunch, I felt inspired enough to create a quick chart that looks at some urban population statistics.

A caveat about the data, it comes from the Census Bureau’s tables on the top-100 cities. So until a city appeared on that list, I did not chart it. The exceptions are 2000 and 2010, where I pulled directly from those census results. Mostly because it was lunch and I needed to be quick about it.
Hint, US Census Bureau, make your interface more friendly.
Credit for this goes to me.
