There are 723,297 houses, apartments and condominiums in the area. Nearly a third of those units — 233,420 — have been built since 2000.
That translates to 32.3 percent of Austin’s housing units being constructed in the 21st century, dwarfing the average of 15.8 percent for all 109 major markets across the country. A major market is defined as any metro with more than 200,000 housing units as of 2011, the latest year for which official figures are available.
Las Vegas led the list with 36.1 percent, followed by Cape Coral, Fla. with 36 percent; McAllen with 33.8 percent; and Raleigh, N.C. with 32.3 percent.
