Overbuilding..

The first and most obvious explanation for the severity of the area's outbreak is that New York is the largest and most densely populated city in the US, and coronavirus tends to spread in dense places.

"That spatial closeness makes us vulnerable," New York Gov. Andrew Cuomo said Wednesday.

New York City had an average of just over 27,000 people per square mile, according to the 2010 Census. That's more than double the density of Chicago and Philadelphia and more than three times the density of Los Angeles.

At all times of day, New Yorkers pack together on the subway, bump into each other on sidewalks and brush knees at bars and restaurants -- all while potentially contagious. They live in crowded apartment buildings, squeezing up stairs or into elevators with neighbors. The transit system connects people across all five boroughs, so most people don't own cars that might otherwise separate people.

With over 8 million people, New York City is also the largest city in the country. So New York's high number of coronavirus cases is also just a reflection of its size. The state will likely lead the country in coronavirus cases even if its infection rate per person is not the highest.

So Mr. De Blasio, enough of the over building in the city. Just a thought.
