You might not think of Colorado Springs as a "big city" but according to the U.S. Census Bureau, it's probably larger than you think. Based on estimated data compiled in July of 2016, Colorado Springs has 465,101 residents across its 194.54 square mile city limit. This makes it the second largest city in the state, but also the 40th most populated city in the country, surprisingly surpassing some much more well-known cities. To be fair, these numbers do not include other suburban areas or total metropolitan areas. In that case, Colorado Springs population would jump to 712,327 but it would be ranked lower. That said, it's still fun to see how Colorado Springs sizes up.
