About the ADP Small Business Report
The ADP Small Business Report is a monthly estimate of private nonfarm employment among companies in the United States with 1-49 employees. In partnership with Macroeconomic Advisers, LLC, the ADP Small Business Report is produced on a monthly basis by ADP® Small Business Services, a provider of payroll, tax management, human resources, professional employer organization (PEO) and administrative services outsourcing (ASO) solutions to small businesses across all industries. ADP® Small Business Services is part of ADP Employer Services, a leader in outsourced payroll, HR and benefits administration solutions. The information included in the ADP Small Business Report is based on data from the ADP National Employment Report, a measure of employment derived from an anonymous subset of 500,000 U.S. business clients. During the last six months of 2006, this subset represented approximately 364,000 U.S. business clients and approximately 22 million U.S. employees working in all private industrial sectors. The data 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 and the ADP Small Business Report are not representative of changes in ADP's total base of U.S. business clients or ADP's total base of U.S. small business clients. The ADP National Employment Report, created by ADP® Employer Services, a division of Automatic Data Processing, Inc. (ADP), in partnership with Macroeconomic Advisers, LLC, is based on actual payroll data and measures the change in total nonfarm private employment each month

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.
