Organization and Staffing

CBO is organized into the following divisions:

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

CBO's staff numbers about 245. Most of those people are economists or public policy analysts with advanced degrees, but 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

The Speaker of the House of Representatives and the president pro tempore of the Senate jointly appoint the CBO Director, after considering recommendations from the two Budget Committees. Directors are appointed for four-year terms, and they may be reappointed to the position; in addition, a Director serving at the expiration of a term may continue to serve until his or her successor is appointed. The Congressional Budget Act of 1974 specifies that CBO’s Director is to be chosen without regard to political affiliation. CBO has had nine Directors and several Acting Directors.

The rest of CBO's staff, including the Deputy Director, are appointed by the Director. CBO Directors have established a firm tradition of retaining staff from their predecessors. Directors appoint all CBO employees solely on the basis of professional competence, without regard to political affiliation.

The Office of the Director is home not only to the Director and Deputy Director but also to the Associate Directors for Economic Analysis, who contribute to all aspects of the agency’s analytic work; the Associate Director for Legislative Affairs, who serves as CBO’s central liaison with the Congress; the Associate Director for Communications and the members of the Office of Communications, who are responsible for CBO’s website and all of the agency’s public affairs activities, including relations with the media and with the public; and the Office of the General Counsel, which performs the agency’s legal work and acquisitions.

In addition, the division also makes key contributions to many of CBO's analytic reports and works on:
