Technical Note
Gross Domestic Product
Second Quarter of 2006 (Preliminary)
August 30, 2006
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 second 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 second quarter was revised from 2.5 percent to 2.9
percent (annual rate).

•
Investment in nonresidential structures was revised up--and investment in
residential structures was revised down--reflecting newly available Census
Bureau value-put-in-place data for June and revised data for April and May.
Inventory investment was revised up, reflecting newly available Census Bureau
inventory data for June and revised data for May.
Exports were revised up, reflecting newly available Census goods data for June.
Spending by state and local governments was revised up, reflecting the Census
Bureau value-put-in-place data.
Corporate Profits
Profits from current production increased $49.5 billion, or 3.2 percent (quarterly rate), in
the second quarter, after increasing $175.6 billion, or 12.6 percent, in the first.
Revisions to Wages and Salaries and Disposable Personal Income
In addition to presenting preliminary estimates for the second quarter, today’s news
release also presents revised estimates of first-quarter wages and salaries, personal
taxes, and contributions for government social insurance. These estimates reflect newly
available wage-and-salary tabulations for the first quarter from the Bureau of Labor
Statistics quarterly census of employment and wages. Wage and salary disbursements
are now estimated to have increased $183.1 billion in the first quarter, an upward
revision of $79.2 billion. Real disposable personal income is now estimated to have
increased 4.6 percent in the first quarter and to have increased 1.5 percent in the
second. (By comparison, the estimates that were available last month showed an
increase of 1.7 percent in the first quarter and an increase of 1.0 percent in the second.

Table A.--SOURCE DATA FOR THE ADVANCE AND PRELIMINARY
ESTIMATES OF GDP FOR THE SECOND QUARTER OF 2006
This table shows the actual data used for the preliminary estimate of GDP for the second quarter of
2006. For these key series, actual data for June were not available in time for inclusion in the
advance GDP estimate released on July 28, 2006, and BEA made assumptions for these source
data. The numbers in brackets show the June values that had been assumed for the advance
estimate. For most series, the data incorporated for May and, in some cases, for April, were
preliminary, and the numbers shown in brackets are the values used last month.
All series shown in the table are in billions of dollars, seasonally adjusted at annual rates, and are
published by the Bureau of the Census.
