Just checked the U.S. Population clock; there are estimated 309,774,892 people in America. When I checked it on February 19, 2009; there were 305,849,952 people. That’s a net gain of 3,924,940 people. Keep in mind that we only built around 554,000 housing units last year…get the picture? I understand that we still have a substantial amount of inventory, but that too will change.
