                          Third Quarter of 2006 (Final)

This technical note provides background information about the source data and 
estimating methods used to produce the estimates presented in the GDP news release. 
The complete set of estimates for the third quarter is available on BEA's Web site at 
www.bea.gov; a brief summary of "highlights" is also posted on the Web site.  In a few 
weeks, the estimates will be published in BEA's monthly journal, the Survey of Current 
Business, along with a more detailed analysis of the estimates ("GDP and the 
Economy").  


Sources of Revision to Components of Real GDP
     
Real GDP growth in the third quarter was 2.0 percent (annual rate), which was 0.2 
percentage point less than that in the preliminary estimate.  The downward revision to 
real GDP mainly reflected a downward revision to consumer spending for services:

    *  The downward revision to consumer spending for services was mostly accounted
       for by medical care services and reflected newly available Census Bureau
       quarterly services survey data.

The price index for gross domestic purchases increased 2.2 percent in the third quarter, 
0.1 percentage point more than in the preliminary estimate.  The price index for state 
and local government spending was revised up, based on newly available price data 
from the Federal Highway Administration.   


Corporate Profits

Profits from current production increased $61.5 billion, or 3.9 percent (quarterly rate), in 
the third quarter, compared with an increase of $22.7 billion, or 1.4 percent, in the 
second.

In the third quarter, real gross value added of nonfinancial corporate business increased, 
and profits per unit of real value added also increased.  Effective with today's release,
the estimates of real gross value added of nonfinancial corporate business were revised 
beginning with 2003, reflecting the use of a revised deflator for nonfinancial industries 
from the annual revision of the GDP-by-industry accounts.
