Organization and Staffing

CBO is organized into the following divisions:

CBO’s collegial work environment and flat organizational structure foster collaboration and teamwork across and within divisions. For example, reports produced by analysts in several divisions rely on economic projections prepared by the Macroeconomic Analysis Division and on cost estimates and budget projections prepared by the Budget Analysis and Tax Analysis Divisions. Similarly, budget projections and cost estimates prepared by the Budget Analysis and Tax Analysis Divisions draw on models and analyses produced by other divisions.

CBO has about 260 staff members, mostly economists or public policy analysts with advanced degrees. The agency also employs lawyers, information technology specialists, editors, and people with other areas of expertise that contribute to the agency’s mission.

Office of the Director

CBO’s Director leads the agency and is supported in that effort by a group of senior staff, members of the Office of Communications, and members of the Office of General Counsel.
