I want to know the answer to the following question:
How many housing units were built in the Bronx in 2002-2007?
All the background I'm provided with is that "In 2006, The New York Times reported that "construction cranes have become the borough's new visual metaphor, replacing the window decals of the 1980s in which pictures of potted plants and drawn curtains were placed in the windows of abandoned buildings."". Is that enough to answer the question?
