Industry classifications

This is a set category. It should only contain pages that are Industry classifications or lists of Industry classifications, as well as subcategories containing those things (themselves set categories). Topics about Industry classifications in general should be placed in relevant topic categories.

Industrial classifications organize economic activity in general, and economic organizations (companies, non-profit organizations, etc.) in particular, into categories generally called "sectors" or "industries", typically defined by the kind of product or service produced.
