This paper documents a Ugandan Social Accounting Matrix (SAM) for the year 2007. The SAM is based on newly estimated supply-use tables, national accounts, government budgets, and balance of payments. The SAM reconciles these data using cross-entropy estimation techniques. The final SAM is a detailed representation of Uganda’s economy. It separates 37 activities and commodities; 5 types of factors of production; and 5 representative household groups.
