Grand Concourse, The Bronx
Typical rows of apartment houses in Bronx Borough.
In older Manhattan multi-family units were known generally as tenements or flats; but when the Bronx began to decelope-with the opening of the first subway transit system 20 years ago- there appeared the modern apartment house. Before the subway came, the Bronx had 250,000 population; now 20 years later it has nearly 900,000.
