1) The Expenditure Approach
This method of determining GDP adds up the market value of all domestic expenditures made on final goods and services in a single year, including consumption expenditures, investment expenditures, government expenditures, and net exports. Add all of the expenditures together and you determine GDP.
2) The Production Approach
This method also called the Net Product or Value added method requires three stages of analysis. First gross value of output from all sectors is estimated.

It’s the only method used for all official purposes within the U.S. and I suppose most other governments. I suppose that includes all USA state governments and all or almost all national governments.
