Technical Note
Gross Domestic Product
Third Quarter of 2010 (Second Estimate)
November 23, 2010
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 Real GDP

The real GDP growth rate in the third quarter was revised from 2.0 percent to 2.5 percent (annual rate).
Upward revisions to consumer spending, to exports, and to state and local government spending were partly
offset by a downward revision to inventory investment.

*       Consumer spending was revised up.  The largest contributors to the revision were “gasoline and
        other energy goods” and “net purchases of used motor vehicles,” based on newly available gasoline
        data for August from the Energy Information Administration (EIA) and on newly available retail
        sales and used motor vehicle registration data.
*       Exports were revised up, primarily based on newly available Census goods data for September.
*       State and local government spending was revised up.  The revision was primarily to gross investment,
        reflecting newly available Census construction spending data for September and revised data for July
        and August.
*       Inventory investment was revised down.  The largest contributor was “mining, utilities, and
        construction” inventories, based on newly available Census Quarterly Financial Report data
        for mining and on newly available EIA data on natural gas, coal, and petroleum stocks for
        utilities.

The price index for gross domestic purchases increased 0.8 percent in the third quarter, the same increase
as in the advance estimate.

Corporate Profits

Profits from current production increased $44.4 billion, or 2.8 percent (quarterly rate), in the third
quarter, after increasing $47.5 billion, or 3.0 percent, in the second.

Revisions to Wages and Salaries and Disposable Personal Income

In addition to presenting revised estimates for the third quarter, today's release also presents revised
estimates of second-quarter wages and salaries, personal taxes, and contributions for government social
insurance.  Wage and salary disbursements are now estimated to have increased $97.4 billion in the second
quarter, an upward revision of $46.3 billion.  These estimates reflect newly available wage and salary
tabulations for the second quarter from the BLS quarterly census of employment and wages.  These data are
more comprehensive than the monthly employment and earnings data that were used for the earlier
estimates—the QCEW data include irregular pay, such as bonuses and gains from the exercise of stock options.

Real disposable personal income is now estimated to have increased 5.6 percent in the second quarter and
0.9 percent in the third.  (By comparison, the estimates that were available last month showed increases
of 4.4 percent in the second quarter and 0.5 percent in the third.)
