There is a huge population of young adults. Some people think New Haven and Hartford are small cities because, unlike anywhere else in the United States, there's a new "town" every 1-2 miles (that's a relic of the 1600s). However if you consider the population density it's actually quite large. For example if you live in New Haven you can drive or take a train for a few minutes and you're in places like Stratford and Derby with dense populations, breweries, etc., that are rarely considered to be part of New Haven even though they are just a few minutes away. Hartford is a short train ride from New Haven and the two cities combined have 2 million people in their center and immediate suburbs. And basically everything along the train line between New Haven and NYC is as densely populated as any of the largest US urban areas.

TLDR, you're moving to a big city, not a "college town." Enjoy.
