General Notes: Data are based on the 2012 North American Industry Classification System (NAICS). NAICS is a set of codes developed by the Office of Management and Budget (OMB) to classify all U.S. businesses. *National Total includes only GDP from metro areas; also known as the "metropolitan portion" of Gross Domestic Product. Median value gives the value for the "average" metro area for this metric, the 50th percentile of all metro areas for which data values were released. Some values were not released due to privacy concerns; others were not released because they are less than $500,000. Neither of those sets of suppressed values are listed or included in national median.
