SQGDP9 Footnotes

1. Real GDP is in millions of chained 2017 dollars. Industry detail is based on the 2017 North American Industry Classification System (NAICS). Calculations are performed on unrounded data. Chained (2017) dollar series are calculated as the product of the chain-type quantity index and the 2017 current-dollar value of the corresponding series, divided by 100. Because the formula for the chain-type quantity indexes uses weights of more than one period, the corresponding chained-dollar estimates are usually not additive. For the All industry total and Government and government enterprises, the difference between the United States and sum-of-states reflects overseas activity, economic activity taking place outside the borders of the United States by the military and associated federal civilian support staff.
