I want to know the answer to the following question:
Some cities in what county have a higher population density than New York City?
All the background I'm provided with is that "In 2014, the city had an estimated population density of 27,858 people per square mile (10,756/km²), rendering it the most densely populated of all municipalities housing over 100,000 residents in the United States; however, several small cities (of fewer than 100,000) in adjacent Hudson County, New Jersey are more dense overall, as per the 2000 Census.". Is that enough to answer the question?
