WASHINGTON (Reuters) - President Barack Obama willoutline new measures next week to boost the U.S. economy afterAugust data Friday showed again that jobs -- the centralissue in November elections -- were being created too slowly.

Obama, speaking to reporters in the White House RoseGarden, greeted a better-than-expected August employment reportthat showed thousands of new private sector jobs were createdas "positive news."

But he said the numbers were not good enough and moreneeded to be done to address U.S. economic woes.

The White House is under pressure to show tangible resultsin lifting growth and hiring before congressional electionsin November, when Obama's Democrats face punishment from votersanxious about near double-digit unemployment.

"I will be addressing a broader package of ideas nextweek," Obama said. "We are confident that we are moving in theright direction. But we want to keep this recovery movingstronger and accelerate the job growth that is needed sodesperately all across the country."

On Monday, the president highlighted a number of possibleoptions including extending middle class tax cuts, investing inclean energy, spending more on infrastructure, and deliveringmore tax cuts to businesses to encourage hiring.

The White House declined to give more specifics about themeasures and a spokeswoman said final decisions had not beenmade.

"We need to take further steps to create jobs and keep theeconomy growing, including extending tax cuts for the middleclass and investing in the areas of our economy where thepotential for job growth is greatest," Obama said.

"In the weeks ahead, I'll be discussing some of these ideasin more detail."

Obama will have ample opportunity to flesh out thosethoughts next week. He is planning to travel to Milwaukee onMonday, the Labor Day holiday, and will visit Cleveland onWednesday. He will also hold a White House news conferenceon Friday, September 10.

The August employment report earlier showed a bigger-than-expected rise of 67,000 in private payrolls, while unemploymentinched up a tenth of a percentage point to 9.6 percent.

Overall, U.S. nonfarm payrolls fell 54,000 as temporaryjobs to conduct the decennial census dropped by 114,000.

"Jobs are being created. They're just not being created asfast as they need to, given the big hole that we experienced,"Obama said.

"We're going to have to continue to work with Republicansand Democrats to come up with ideas that can further acceleratethat job growth. I'm confident that we can do that." (Additional reporting by Patricia Zengerle; Editing by Doina Chiacu)
