NAICS - Primary Business Activity

According to the U.S. Census Bureau, the primary business activity of an establishment is determined by relative share of production costs and/or capital investment. In practice, other variables, such as revenue, value of shipments, or employment, are used as proxies. The U.S. Census Bureau generally uses revenue or value of shipments to determine an establishment's primary business activity.
