“National wealth” refers to the total value of wealth possessed by the citizens of a nation at a set point in time. That is, the total value of wealth and goods generated by all economic activity in a nation. National wealth is of great help in economic development planning and in carrying out economic analyses. The scope of this statistic (that is, gross national wealth) is defined as the total value of assets including tangible assets and net foreign assets possessed by all economic departments (i.e., all citizens) of a nation at a set point in time. The former includes the total value of tangible assets that may be regenerated and the estimated value of registered land. Gross national wealth is used to represent the production and service potential of assets and net national wealth calculated by deducting depreciation from current assets, which is used to represent the residual value and degree of usage of the assets.
