In economics, the distinction between stock and flow variables is fundamental. National Wealth is defined as the total value of all assets, commodities, and economic goods possessed by the citizens of a nation at a specific point in time [t1][t2]. It represents a 'stock' variable because it measures the accumulated holdings at a particular moment [t3][t9]. In contrast, National Income is a 'flow' variable, representing the total value of goods and services produced or income earned over a period of time, typically a year [c1][c4][t9]. While National Resources refer to the underlying natural or human potential of a country, and Per Capita Income is an average flow measure [t5], the specific stock of commodities and assets held by nationals at a given point in time is formally termed National Wealth [t10].
