Source: Conventional GDP and NDP in 1987 prices were calculated by BEA (U.S. Congress Economic Report of the President, 1995). GDP with mineral additions was calculated based on data in columns (1) and (3) and estimates of mineral additions and depletions from Bureau of Economic Analysis (1994b:60). Mineral additions and depletions in this calculation rely on current rent method I.
