Private Sector Contribution to GDP

Once upon a time the United States rivaled only with Germany for manufacturing superiority.  However, the American economy over the past 63 years has evolved from a country who's economy was driven by manufacturing to a country that is now largely a service nation.  Another fundamental shift is taking place in the economy again as the U.S. moves towards a predominately financialized  economy, but that is a discussion for a different day.

The data displayed below depicts three broad industry categorizations.  Finance, Insurance, and Real Estate include all companies that engage in financial transactions for the sole means of profits.  Manufacturing firms include all firms that produce durable and non-durable goods.  Services does not include any government transactions or public utilities as is often included in this account.  I have not included government services as to only display the private sectors contribution to GDP.  In measuring GDP i have also excluded from the aggregate number any government contributions, again to isolate the private sector. 

Data: BEA's Gross Product Origination

The three sectors shown above account for the largest contributions to GDP.  Since 1947 the average combined contribution to GDP is 61.63% with a standard deviation of 3.54%.
