Real gross domestic product -- the output of goods and services produced by labor and property
located in the United States -- increased at an annual rate of 2.5 percent in the first quarter of 2013 (that
is, from the fourth quarter to the first quarter), according to the "advance" estimate released by the
Bureau of Economic Analysis.  In the fourth quarter, real GDP increased 0.4 percent.

      The Bureau emphasized that the first-quarter advance estimate released today is based on source
data that are incomplete or subject to further revision by the source agency (see the box on page 3 and
"Comparisons of Revisions to GDP" on page 5).  The "second" estimate for the first quarter, based on
more complete data, will be released on May 30, 2013.

      The increase in real GDP in the first quarter primarily reflected positive contributions from
personal consumption expenditures (PCE), private inventory investment, exports, residential investment,
and nonresidential fixed investment that were partly offset by negative contributions from federal
government spending and state and local government spending.  Imports, which are a subtraction in the
calculation of GDP, increased.

     Comprehensive Revision of the National Income and Product Accounts

     BEA plans to release the results of the 14th comprehensive (or benchmark) revision of the national
income and product accounts (NIPAs) in conjunction with the second quarter 2013 "advance" estimate
on July 31, 2013.  More information on the revision is available on BEAs Web site at
www.bea.gov/gdp-revisions, including a link to an article in the March 2013 issue of the Survey of
Current Business that discusses the upcoming changes in definitions and presentations, including
capitalizing spending on research and development and on entertainment originals and measuring
transactions of defined benefit pension plans on an accrual accounting basis.  An article in the May
Survey will describe changes in statistical methods, and an article in the September Survey will describe
the estimates in detail.  Revised NIPA table stubs and news release stubs will be available in June.

___________________________

      The acceleration in real GDP in the first quarter primarily reflected an upturn in private
inventory investment, an acceleration in PCE, an upturn in exports, and a smaller decrease in federal
government spending that were partly offset by an upturn in imports and a deceleration in nonresidential
fixed investment.

      Motor vehicle output added 0.24 percentage point to the first-quarter change in real GDP after
adding 0.18 percentage point to the fourth-quarter change.  Final sales of computers subtracted 0.01
percentage point from the first-quarter change in real GDP after adding 0.10 percentage point to the
fourth-quarter change.

      The price index for gross domestic purchases, which measures prices paid by U.S. residents,
increased 1.1 percent in the first quarter, compared with an increase of 1.6 percent in the fourth.
Excluding food and energy prices, the price index for gross domestic purchases increased 1.3 percent in
the first quarter, compared with an increase of 1.2 percent in the fourth.

      Real personal consumption expenditures increased 3.2 percent in the first quarter, compared with
an increase of 1.8 percent in the fourth.  Durable goods increased 8.1 percent, compared with an increase
of 13.6 percent.  Nondurable goods increased 1.0 percent, compared with an increase of 0.1 percent.
Services increased 3.1 percent, compared with an increase of 0.6 percent.

      Real nonresidential fixed investment increased 2.1 percent in the first quarter, compared with an
increase of 13.2 percent in the fourth.  Nonresidential structures decreased 0.3 percent, in contrast to an
increase of 16.7 percent.  Equipment and software increased 3.0 percent, compared with an increase of
11.8 percent.  Real residential fixed investment increased 12.6 percent, compared with an increase of
17.6 percent.

      Real exports of goods and services increased 2.9 percent in the first quarter, in contrast to a
decrease of 2.8 percent in the fourth.  Real imports of goods and services increased 5.4 percent, in
contrast to a decrease of 4.2 percent.

      Real federal government consumption expenditures and gross investment decreased 8.4 percent
in the first quarter, compared with a decrease of 14.8 percent in the fourth.  National defense decreased
11.5 percent, compared with a decrease of 22.1 percent.  Nondefense decreased 2.0 percent, in contrast
to an increase of 1.7 percent.  Real state and local government consumption expenditures and gross
investment decreased 1.2 percent, compared with a decrease of 1.5 percent.

      The change in real private inventories added 1.03 percentage points to the first-quarter change in
real GDP after subtracting 1.52 percentage points from the fourth-quarter change.  Private businesses
increased inventories $50.3 billion in the first quarter, following increases of $13.3 billion in the fourth
quarter and $60.3 billion in the third.

      Real final sales of domestic product -- GDP less change in private inventories -- increased 1.5
percent in the first quarter, compared with an increase of 1.9 percent in the fourth.


Gross domestic purchases

      Real gross domestic purchases -- purchases by U.S. residents of goods and services wherever
produced -- increased 2.9 percent in the first quarter; it was unchanged in the fourth quarter.


Disposition of personal income

      Current-dollar personal income decreased $109.1 billion (3.2 percent) in the first quarter, in
contrast to an increase of $262.3 billion (8.1 percent) in the fourth.  The downturn in personal income
primarily reflected a sharp downturn in personal dividend income and a sharp acceleration in
contributions for government social insurance -- a subtraction in the calculation of personal income.
Fourth-quarter personal dividend income was boosted by the payment of accelerated and special
dividends. The acceleration in contributions for government social insurance in the first quarter resulted
from the expiration of the "payroll tax holiday."

      Personal current taxes increased $27.2 billion in the first quarter, compared with an increase of
$34.3 billion in the fourth.

      Disposable personal income decreased $136.3 billion (4.4 percent) in the first quarter, in contrast
to an increase of $228.0 billion (7.9 percent) in the fourth.  Real disposable personal income decreased
5.3 percent, in contrast to an increase of 6.2 percent.

      Personal outlays increased $116.3 billion (4.1 percent) in the first quarter, compared with an
increase of $97.0 billion (3.4 percent) in the fourth.  Personal saving -- disposable personal income less
personal outlays -- was $313.3 billion in the first quarter, compared with $566.0 billion in the fourth.

      The personal saving rate -- personal saving as a percentage of disposable personal income -- was
2.6 percent in the first quarter, compared with 4.7 percent in the fourth.  For a comparison of personal
saving in BEAs national income and product accounts with personal saving in the Federal Reserve
Boards flow of funds accounts and data on changes in net worth, go to
www.bea.gov/national/nipaweb/Nipa-Frb.asp.


Current-dollar GDP

      Current-dollar GDP -- the market value of the nation's output of goods and services -- increased
3.7 percent, or $146.1 billion, in the first quarter to a level of $16,010.2 billion.  In the fourth quarter,
current-dollar GDP increased 1.3 percent, or $53.1 billion.

                                            Comparisons of Revisions to GDP

     Quarterly estimates of GDP are released on the following schedule:  the "advance" estimate, based on
source data that are incomplete or subject to further revision by the source agency, is released near the end of the
first month after the end of the quarter; as more detailed and more comprehensive data become available,
the "second" and "third" estimates are released near the end of the second and third months, respectively.
The "latest" estimate reflects the results of both annual and comprehensive revisions.

     Annual revisions, which generally cover the quarters of the 3 most recent calendar years, are usually carried
out each summer and incorporate newly available major annual source data.  Comprehensive (or benchmark)
revisions are carried out at about 5-year intervals and incorporate major periodic source data, as well as
improvements in concepts and methods that update the accounts to portray more accurately the evolving U.S.
economy.

The table below shows comparisons of the revisions between quarterly percent changes of current-dollar
and of real GDP for the different vintages of the estimates.  From the advance estimate to the second estimate (one
month later), the average revision to real GDP without regard to sign is 0.5 percentage point, while from the
advance estimate to the third estimate (two months later), it is 0.6 percentage point.  From the advance estimate to
the latest estimate, the average revision without regard to sign is 1.3 percentage points.  The average revision
(with regard to sign) from the advance estimate to the latest estimate is 0.2 percentage point, which is larger
than the average revisions from the advance estimate to the second or to the third estimates.  The larger average
revisions to the latest estimate reflect the fact that comprehensive revisions include major improvements, such as
the incorporation of BEAs latest benchmark input-output accounts.  The quarterly estimates correctly indicate the
direction of change of real GDP 97 percent of the time, correctly indicate whether GDP is accelerating or
decelerating 72 percent of the time, and correctly indicate whether real GDP growth is above, near, or below trend
growth more than four-fifths of the time.
