If all goes as planned, President-elect Barack Obama will sign a massive federal stimulus bill shortly after taking office next month. A major goal of the plan is to create at least 2.5 million jobs, but it's a number that's looking smaller as time goes by.

The U.S. Labor Department said Thursday that initial claims for state unemployment benefits rose to 573,000 last week. Unemployment is rising, and not just because of weak sales in the nation's consumer-based economy—offshore outsourcing may be accelerating as companies seek to cut costs.

But how many tech jobs might be saved or created by a federal stimulus package? Obama has already released a broad outline of a plan that calls for heavy tech investments in schools, health care, broadband networks and energy. But the details of those sketched-out plans could determine which tech industries fare well and which ones don't.

If the Obama administration favors WiMax over wires as a way to connect and improve IT in schools, for instance, the need for tech workers to do the job may slacken, said Rob Enderle, an independent IT consultant in San Jose, Calif.

Enderle pointed to AT&T's recently announced layoff of 12,000 people, which is affecting many of its landline workers. "If part of your goal is to employ more people, maybe you don't use WiMax because you actually want people out there pulling cable," he said. Less money spent on tech projects could mean more money for road building; that's why Enderle estimates that of the 2.5 million jobs Obama envisions, just between 50,000 to 200,000 would go to tech workers.

Estimates about the size of the nation's tech workforce vary. One group, the National Association of Computer Consultant Businesses in Alexandria, this week put it at about 3.87 million and said tech employment is now declining. That's out of a total labor force of about 154 million U.S. workers.

Katherine McGuire, vice president of government relations for the Business Software Alliance, said if Obama's "pro-tech agenda" is pushed forward in its entirety, the nation could see a 10 percent gain in tech jobs. That would represent an increase of about 300,000 high-paying IT jobs.

McGuire noted that IT isn't the lone driver for high-skills jobs. Obama "is right to seek incentives for innovation and growth across the entire economy, which in turn will spur more growth in the IT sector."
