What Does Section K Cover in ISIC Rev. 5?

Section K in ISIC Rev. 5, UN Statistics Division, covers telecommunications, computer programming, consultancy, computing infrastructure and other information services. It was created when the old Rev. 4 Section J was split, so that content production stayed in the new Section J while carriage, software and computing services moved here. Section K therefore describes the networks, software and data services that carry, process and organise information, rather than the content itself.

Which five kinds of service share this one section?

Section K gathers five kinds of service that share a common trait: they carry, process or organise information rather than creating content itself. Telecommunications activities move voice, data, text, sound and video between users. Computer programming activities write, modify and test software. Computer consultancy advises on systems, and computer facilities management operates a client’s systems on its behalf. Computing infrastructure, data processing and hosting supply the capacity and facilities that run software and store data for others. Web search portals and other information services help users find or use information. Development of video games sits in this neighbourhood where the UNSD structure places that work here, with the caution that publishing and live operation are described separately. The section was created when the old Rev. 4 Section J was split, so that content production stayed in the new Section J while carriage, software and computing services moved here, and that history explains why the five kinds sit together.

How can one company sell programming, hosting and connectivity at once?

Take the bundled company example and unpack its invoice. A company builds a business application for a client, writing code for orders and stock, hosts that application on its own servers so the client’s staff can reach it from any office, and provides telephone and internet connectivity to those offices. The client signs one contract, deals with one account manager, and pays one monthly bill, yet three Section K activities are present: programming in the code that was written, hosting in the servers that run it, and telecom in the connectivity that links the offices. ISIC Rev. 5, UN Statistics Division, describes each service separately even when one company sells them as a bundle, and the principal activity decides the overall placement for statistical purposes. A reader who labelled the whole company by its best known service, perhaps the application everyone talks about, would hide the hosting and telecom work that also earn income and employ staff.

What stays outside even though it touches computers or screens?

Four kinds of work touch computers or screens yet stay outside Section K, and they are worth listing because they cause the most confusion. Publishing books, films or music stays in Section J, because the task is creating and issuing content, not carrying or processing it. Broadcasting programmes stays in Section J for the same reason: the broadcaster creates a scheduled service, even when it travels over a telecom network. Manufacturing computers or telecom equipment stays in manufacturing, because making a device is not operating it or writing its software. Retailing software or devices to consumers stays in trade, because selling a finished product is not the same as writing, hosting or carrying a service. Each exclusion sharpens Section K by showing what it is not, and each one should be checked in the UNSD structure, since a business that does both a Section K task and an excluded task needs its principal activity identified before any total is chosen.

Why does a shared section still demand separate descriptions?

Sharing a section does not mean sharing a description. Networks and software now underpin almost every other industry, from health to transport, and if telecom, programming and hosting were buried inside content or manufacturing totals, analysts could not see investment in connectivity and computing, or compare countries on digital infrastructure and software capacity. Section K solves that burial problem at section level, but the work is only finished when each activity inside the section is also described separately. Otherwise Section K itself would become a new crowded household, repeating the old Section J problem at a smaller scale. ISIC Rev. 5, UN Statistics Division, contains 22 sections from A to V, with 87 divisions, 258 groups and 463 classes in total, and those finer levels exist precisely so that a shared section can still yield separate, comparable totals for telecom, programming, consultancy, hosting and information services.

This guide maps a section, it does not place any particular business inside it. It does not determine any reader’s code, principal activity or registration, and a reader who needs a code for a real activity should confirm it with the national statistical institute or business register that holds the record.
