Industries in the Administrative and Support Services subsector group establishments engaged in activities that support the day-to-day operations of other organizations.

The establishments classified in this subsector have specialization in one or more of these activities and can, therefore, provide services to clients in a variety of industries and, in some cases, to households. The individual industries of this subsector are defined on the basis of the particular process that they are engaged in and the particular services they provide.
Many of the activities performed in this subsector are ongoing routine support functions that all businesses and organizations must do and that they have traditionally done for themselves. Recent trends, however, are to contract or purchase such services from businesses that specialize in such activities and can, therefore, provide the services more efficiently.
The industries in this subsector cannot be viewed as strictly "support."" The Travel Arrangement and Reservation Services industry group includes travel agents
