WASHINGTON (AP) — The chairman of the White House Council of Economic Advisers says the latest jobs report offers signs of an improving economy. But he acknowledges more work needs to be done.

In a statement, Alan Krueger notes that 103,000 jobs were added in the private sector in the last month for the 30th straight month. He pointed to improvement in particular for the leisure, business services and health care sectors.

Krueger says President Barack Obama has been working to create more jobs for the middle class but that a jobs bill the president proposed has stalled in Congress.

The unemployment rate fell to 8.1 percent in August, from 8.3 percent in July. That was largely due to more people who gave up looking for work.
