The relative performance of states or particular industries within states can be assessed by examining their real growth rates and shares of current-dollar GDP by state. For example, comparing an industry’s real growth rate of chained-dollar GDP by state to the growth rate of total chained-dollar GDP by state indicates whether that industry is raising or lowering the state's growth rate. Comparing the share of total GDP by state in current dollars that is accounted for by an industry’s GDP by state over time indicates whether that industry's claim on the state's resources is increasing or decreasing.
