36. Union City, New Jersey

Union City is one of the most densely populated areas in the entire country, as 68,500 residents are packed into just over one square mile. But, despite the number of people living in such proximity, the city seems to be lacking in resources.

23% of the population lives in poverty, which is not aided by New Jersey’s overall high cost of living. Although you’d think there’d be plenty of employment opportunities in the area, the average commute time is over 30 minutes.
