Intelligence spending has increased by a third over 10 years ago, in inflation adjusted dollars, according to Steve Kosiak at the Center for Strategic and Budgetary Assessments.
How the money is divided among the 16 intelligence agencies and exactly what it is spent on is classified. It includes salaries for about 100,000 people, multibillion dollar secret satellite programs, aircraft, weapons, electronic sensors, intelligence analysts, spies, computers and software.
Much of the intelligence budget ---about 70 percent---goes to contractors for the procurement of technology and services including analysis, according to a May 2007 chart from the DNI's office.
For comparison, last year's intelligence spending was about half the $91 billion President Bush is proposing to spend over the coming year on the Agriculture Department.
