Budget Deficit
A budget deficit is a period shortfall when government expenditure exceeds revenue under a stated accounting boundary and measurement basis.
Core public-finance guides to measuring a budget deficit and evaluating policies intended to reduce it.
Public Budget Deficits and Fiscal Balances explains the headline government shortfall and the policy choices used to narrow it. The section treats budget deficit, fiscal deficit, and federal deficit as context-dependent names for the same core period measure rather than presenting synonyms as separate articles.
Start with Budget Deficit for formulas, measurement boundaries, primary versus headline balances, financing, and the distinction between deficit and debt. Use Deficit Reduction when the question concerns policies intended to reduce that shortfall.
