If you subscribe to the notion that any growth in jobs is good, then today’s report from ADP will be encouraging. The payroll processor said 91,000 new private sector jobs were created in August.

That’s still less than the 100,000 economists were expecting, and it’s about a third of what the U.S. needs each month to bring down the unemployment rate. The company, and Macroeconomic Advisers, its partner in the monthly report, also adjusted downward its July estimate to 109,000 from the original 114,000.

In ever-so-cautious language, the report says that the slow job growth in August is “at a pace below what would be consistent with a stable unemployment rate.” That means that should the trend continue, unemployment may rise.

Economists expect that when the official employment numbers are released Friday by the U.S. Department of Labor, they’ll show the 9.1 percent unemployment rate unchanged. New jobs are expected to be somewhere in the neighborhood of 75,000 (Bloomberg News) to 80,000 (Dow Jones Newswires).
