What are NYC's youngest, oldest, richest and poorest neighborhoods? ‘Factfinder’ knows.

More Dominicans live in Washington Heights than any other neighborhood, Yorkville is the city’s densest neighborhood and South Williamsburg is the youngest, according to data from the U.S. Census Bureau.

The data published Tuesday by the Department of City Planning at its online Population FactFinder was “another example of how we’re celebrating the melting pot that makes New York New York,” the department's Director Dan Garodnick said in a statement.

The FactFinder and an accompanying MapViewer present an array of economic and demographic information about the city, as well as its many racial and ethnic groups.

For instance, Jamaica has more Bangladeshi residents than any other neighborhood and South Ozone Park is the city’s largest Guyanese neighborhood.

Jackson Heights has the most Hispanic residents of any neighborhood at 54,300. Dominicans are the largest Hispanic group in the Bronx and Manhattan, according to the department, while Ecuadorians are the largest Hispanic group in Queens. In Brooklyn and Staten Island, Puerto Ricans are the largest Hispanic group.
