Official SingStat Definition & Scope
This section includes a variety of activities that support general business operations. These activities are often undertaken in-house by establishments in various sections. The economic units in this section specialise in one or more of these support activities and typically provide these services to clients in a variety of industries and, in some cases, to households on a contract or fee basis. These activities differ from those in section N 'Professional, Scientific And Technical Activities', since their primary purpose is not the transfer of specialised knowledge and therefore this section includes office administration, hiring and placing of personnel, security and surveillance services and cleaning services.
