The graphical trend of GDP since 2008. While it has improved since 2008, the economy is still somewhat stagnant, as per this graphical display. Of course, other items must be analyzed while looking at economic growth. Recall: GDP is the final numbers, not the purchases of the intermediate goods for the production process.
With Gross Output of all industries, it shows intermediate goods purchases, some that are included in the GDP number. These purchases are typically purchase of goods or inputs prior to the final sale of the products. The GDP number reflects the final sale, the GO numbers, for the most part, are pre sale to consumers.
