Texas is in a league of its own when it comes to economic expansion.

The total personal income (TPI) in Texas reached $1.07 trillion dollars in the second quarter of this year, according to the U.S. Bureau of Economic Analysis. That's an increase of 71 percent from the state's corresponding total 10 years earlier, $626.7 billion.

Here's another way of looking at it: Texas accounted for 8.02 percent of the nation's TPI this year, up 1.10 percentage points from 6.92 percent in 2002.
