ADP Automatic Data Processing Inc

According to today's ADP National Employment Reportďż˝, private sector employment decreased by 693,000 in December. The ADP National Employment Report, created by ADPďż˝ Employer Services, a division of Automatic Data Processing, Inc. (ADP), in partnership with Macroeconomic Advisers, LLC, is derived from actual payroll data and measures the change in total nonfarm private employment each month.

Beginning this month, the ADP Report will incorporate methodological improvements intended to improve the correspondence between the nonfarm private employment estimates shown in the ADP Report and estimates published in the Bureau of Labor Statistics' Employment Situation Report.

Nonfarm Private Employment Highlights - December Report:

-- Total employment:               -693,000

-- Small businesses*               -281,000
-- Medium businesses**             -321,000
-- Large businesses***              -91,000

-- Goods-producing sector:         -220,000

-- Service-providing sector:       -473,000

Addendum:
-- Manufacturing industry:         -120,000

* Small businesses represent payrolls with 1-49 employees
** Medium businesses represent payrolls with 50-499 employees
*** Large businesses represent payrolls with more than 499 employees

According to Joel Prakken, Chairman of Macroeconomic Advisers, LLC, "Nonfarm private employment decreased 693,000 from November to December 2008 on a seasonally adjusted basis, according to the ADP National Employment Report. This month's ADP Report incorporates methodological improvements intended to improve the correspondence between the nonfarm private employment estimates shown in the ADP Report and estimates published in the Bureau of Labor Statistics' Employment Situation Report."

Prakken added, "December's ADP Report estimates nonfarm private employment in the service-providing sector fell by 473,000. Employment in the goods-producing sector declined 220,000, the twenty-third consecutive monthly decline. Employment in the manufacturing sector declined 120,000, marking its twenty seventh decline over the last twenty eight months."

"Large businesses, defined as those with 500 or more workers, saw employment decline 91,000, while medium-size businesses with between 50 and 499 workers declined 321,000. Employment among small-size businesses, defined as those with fewer than 50 workers, declined 281,000. Sharply falling employment at medium- and small-size businesses clearly indicates that the recession has now spread well beyond manufacturing and housing-related activities," said Prakken.

Prakken went on to say, "In December, construction employment dropped 102,000. This was its twenty-first consecutive monthly decline, and brings the total decline in construction jobs since the peak in January 2007 to 809,000."

The matched sample used to develop the ADP National Employment Report was derived from ADP data which, during the last six months of 2008, averaged approximately 400,000 payrolls representing nearly 24 million U.S. employees. This approximately represents the size of the matched sample used this month.

Small Business Highlights - December Report:

Due to the important contribution small businesses make to economic growth, employment data that is specific to businesses with fewer than 50 employees will be reported in the ADP Small Business Reportďż˝ each month. The ADP Small Business Report is a subset of the ADP National Employment Report.

--  Total small business employment: -281,000
--  Goods-producing sector: -80,000 small business jobs
--  Service-providing sector: -201,000 small business jobs
    

Private employment among small businesses decreased by 281,000 in December, according to the ADP Small Business Report released today. Additional information about small business employment, including charts on monthly job growth and employment levels, along with historical data, is available at http://www.smallbusinessreport.adp.com.

"Employment among small-size businesses, defined as those with fewer than 50 workers, declined 281,000. Though the severity of job losses in recent months among small-size businesses has been less than that at larger-size ones, today's employment declines clearly indicate that the recession has widened to include businesses of all sizes," said Joel Prakken.

About the ADP National Employment Reportďż˝

The ADP National Employment Report, sponsored by ADPďż˝, was developed and is maintained by Macroeconomic Advisers, LLC. It is a measure of employment derived from an anonymous subset of roughly 500,000 U.S. business clients. During the last six months of 2008, this subset represented approximately 400,000 U.S. business clients and nearly 24 million U.S. employees working in all private industrial sectors. The ADP Small Business Reportďż˝ is a monthly estimate of private nonfarm employment among companies in the United States with 1-49 employees and is a subset of the ADP National Employment Report. The data for both reports is collected for pay periods that can be interpolated to include the week of the 12th of each month, and processed with statistical methodologies similar to those used by the U.S. Bureau of Labor Statistics to compute employment from its monthly survey of establishments. Due to this processing, this subset is modified to make it indicative of national employment levels; therefore, the resulting employment changes computed for the ADP National Employment Report are not representative of changes in ADP's total base of U.S. business clients.

For a description of the underlying data and the statistical properties of the series, please see "ADP National Employment Report: Development Methodology" at http://ADPemploymentreport.com/methodology.aspx.
