There's no denying that Dallas-Fort Worth's population is booming, and to keep up, the metro is expanding at a rapid rate. BuildZoom recently conducted an in-depth study on metropolitan growth in the U.S., revealing DFW's growth patterns.

Since the 1970s, the Dallas metro area's expansion rate has increased by 48 percent, making it the eighth most rapidly expanding city in the nation.

To put that into perspective, DFW added 269 square miles of urban development in the 1970s. From 2000-2009, we gained a whopping 398 square miles. Only Atlanta added more land during that time: 632 square miles. Houston was third, with 393 square miles.

Austin's expansion rate has increased by 123.5 percent since the 1970s. Only two cities are expanding more rapidly: Raleigh, North Carolina, No. 1, and Charlotte, North Carolina, at No. 2.

So just how big are we? In 2010, DFW clocked in at 1,833 square miles. Watch the metro area's growth from the 1940s on below:
