ADP®, a leader in human capital management services, and Moody's Analytics, a leading independent provider of economic forecasting, today announced enhancements to the ADP National Employment Report®, ADP's widely followed gauge of U.S. nonfarm private sector employment.

The newly expanded ADP National Employment Report will be issued each month by the ADP Research Institute(SM), a specialized group within ADP that provides insights around employment trends and workforce strategy. The first enhanced monthly report issued in collaboration with Moody's Analytics will be released on November 1, and will report private payroll changes for the month of October 2012.

"Our new strategic collaboration with Moody's Analytics marks the beginning of an exciting stage in the evolution of the ADP National Employment Report, as we work to offer an even deeper, richer and more illuminating look at U.S. monthly employment," said Jan Siegmund, Chief Strategy Officer, ADP. "Moody's Analytics is one of the most trusted names in economic forecasting with a vast and dedicated research team focused on national and regional U.S. employment trends. This team is led by their Chief Economist Mark Zandi, one of the world's most respected labor market experts. We look forward to working closely with the Moody's Analytics team to provide an insightful analysis of the changes in the U.S. labor market."

This new collaboration allows the ADP National Employment Report to increase the number of industry categories reported and expands the number of business sizes reported each month. Other key enhancements of the report include the development of a new methodology to further align with the final, revised U.S. Bureau of Labor Statistics (BLS) numbers. A look back at historical data from 2001 to present using the new methodology shows a very strong correlation (96%) with the revised BLS numbers. In addition, the overall sample size used to create the report has been increased from 344,000 U.S. companies to 406,000, and from 21 million employees to 23 million; which accounts for more than 20% of all U.S. private sector employees. Originally launched in 2006, the ADP National Employment Report is a derived from actual payroll data from an anonymous subset of ADP's clients in the U.S.

"The ADP National Employment Report is derived from transactional payroll data and not just survey data, making it a powerful labor market indicator," said Mark Zandi, Chief Economist at Moody's Analytics. "Drawing from this input and the national and regional knowledge provided by Moody's Analytics' dedicated team of economists, we are enhancing the monthly report, which we are confident will further align the ADP National Employment Report findings with the BLS's fully revised numbers."

The previous report provided three company-size classes. The enhanced ADP National Employment Report offers data according to five company-size classes:

• 1-19 employees
• 20-49 employees
• 50-499 employees
• 500-999 employees
• 1000 or more employees

In addition, the enhanced report will provide an expanded snapshot of the monthly change in nonfarm private sector employment by moving from reporting on three industries to five industries. The five industries reported constitute more than 50% of all U.S. private sector employment. The industries are aligned with the North American Industrial Classification System (NAICS), the system endorsed by the U.S. Bureau of Labor Statistics. The five industries are:

• Construction
• Financial Activities
• Manufacturing
• Professional and Business Services
• Trade, Transportation and Utilities
