USA Economy -- Prediction by Economist

In a special edition of The Economist, THE WORLD IN 2012, page 115, GDP was expected to grow at 1.3% with an inflation rate of 2.1%, and a GDP per head of $49,340.

Amosweb.com has GDP growing at 1.9% and inflation at 1.7%.

I think the economy in North America grows on the availability of gas.  When gas is cheap consumers spend more.
