Definition

Value added by professional, scientific, and technical services (legal, accounting, engineering, computer systems design, consulting, research and advertising) (NAICS 54), the industry's contribution to gross domestic product (GDP), in millions of current US dollars. United States and states: Bureau of Economic Analysis GDP by state, table SAGDP2, line 60.

Millions of current US dollars, not adjusted for inflation; for real growth of the whole economy use gdp_growth. Industries are the sectors of the 2017 North American Industry Classification System (NAICS), counted where production takes place. The 20 sector values of a place add up to its gdp_usd, apart from rounding. BEA leaves out values that would disclose a single company, marked (D), and values below $50,000, marked (L); they are missing here, not zero.
