A Social Accounting Matrix is a comprehensive map of all economic transactions between sectors and actors in an economy, showing how money flows through production, income, consumption, and trade. This structure lets you see how a policy change would ripple across the economy by tracing adjustments in production, household income, demand, and government receipts and expenditures. Because you can simulate changes in taxes, subsidies, transfers, or public spending and observe the resulting shifts in outputs, incomes, and demand across sectors, a SAM is ideal for understanding the current state of the economy and assessing the likely effects of policy proposals. It also supports calculating multipliers and distributional impacts, which is central to policy analysis. The other options don’t fit because population growth forecasting, wildlife habitat measurement, and building layout design are not economic-accounting tasks and aren’t served by the interlinked transaction framework a SAM provides.
