The U.S. is one of the world’s largest countries in terms of both area and population. Interestingly, though, some of America’s biggest and most populous cities aren’t the capitals of their respective states. For example, while New York City — home to nearly 8.5 million people — is the most populated city in the U.S., Albany is the New York state capital, with a population of less than 100,000. Some state capitals — like Montpelier, Vermont and its 8,000 residents — are even tinier. But of course, there are some capital cities that are far bigger, even ranking among the most populous cities in the country. Check out the eight most populous U.S. state capitals below.
