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 "Geographically co-extensive with New York County, the borough of Manhattan's population density of 71,672 people per square mile (27,673/km²) makes it the highest of any county in the United States and higher than the density of any individual American city.". Is that enough to answer the question?
Answer: no
