Where Do Intermediation Classes Sit Across Sections in Rev. 5?

In ISIC Rev. 5, published by the UN Statistics Division, intermediation classes are spread across sections because intermediation is a way of working, not a single industry. A class for arranging transport sits near transport, a class for arranging accommodation sits near accommodation, and so on. That placement keeps the arranging activity close to the market it serves, which helps readers find it in context.

Why is there no single home for all arranging work?

Readers hunting for one intermediation section will not find one, and that absence is deliberate. Intermediation is a way of working that appears in many markets, not a market of its own. Arranging transport belongs near transport, arranging accommodation belongs near accommodation, arranging care belongs near care, and so on. Placing each arranging class beside the market it serves keeps it visible to readers who already know that market, instead of hiding all arranging work in a distant corner of the classification where market specialists would never look.

How does market placement help a reader find the right class?

Start from the market, not from the word intermediation. A reader tracing a transport arranging business should begin in the transport area of the structure, look for the arranging activity within or near it, and read its full description. The same approach works for accommodation, care, professional services, and other markets. The section heading gives useful context about the market, but it does not define the activity; the class description does that work, with its inclusions and exclusions marking what counts and what does not.

This market first approach also prevents a common shortcut: searching the whole classification for the word intermediation and picking the first hit. That shortcut ignores market context and can land a reader in the wrong part of the structure entirely, with a class that describes arranging in a different market. Patience at the market stage, reading neighbouring classes as well as the promising one, usually pays off, because neighbouring classes often state explicitly that arranging work sits elsewhere.

What do a freight platform and a care platform share, and what divides them?

Both platforms intermediate: they match customers with providers, handle bookings, and earn fees for arranging rather than delivering. That shared idea is why Rev. 5 treats them as the same kind of work in general terms. Yet they sit in different parts of the structure because their markets differ, and that difference matters for statistics. Freight arranging figures belong with freight analysis, where analysts study logistics, trade, and transport capacity. Care arranging figures belong with care analysis, where analysts study access to care, funding, and provision. Merging them into one distant total would serve neither analysis well.

How should a reader narrow from a whole section to one class?

Move through the UNSD Rev. 5 classification detail step by step, from section to division to group to class, checking the description at each level against a plain account of the work. At section level, the question is market: transport, accommodation, care, or something else. At division and group level, the question narrows to the kind of activity within that market. At class level, the question is precise: does this description, with its inclusions and exclusions, match arranging work in this market, or does it describe supplying the service itself? A class that looks promising at title level can still fail at description level, which is why titles alone are never enough.

The scale of the structure explains why that narrowing matters. For intermediation classes, Rev. 5 published by the UN Statistics Division has 22 sections from A to V, 87 divisions, 258 groups, and 463 classes, endorsed by the UN Statistical Commission in March 2023. With that many headings, two classes can share similar words while describing different work, and only the full descriptions separate them. National guidance then adds the local layer, explaining how international headings are applied in a particular country’s business register.

Why does placement by market improve comparison across countries?

When every country places transport arranging near transport and care arranging near care, their statistics line up market by market, even when local business names, platforms, and regulations differ. A country that placed all arranging work in one section would break that alignment, because its transport figures would exclude arranging while another country’s included it nearby. Market placement therefore protects comparability where it matters most: inside each market’s own analysis, where policymakers, researchers, and businesses actually use the figures.

That protection only works if readers resist copying headings from similar businesses. Two platforms can share a name style, a website design, and a customer type while arranging in different markets, and their classes will rightly differ. Comparison of descriptions, not of names, is what keeps the structure honest.

For a formal answer, this guide points readers to the UNSD structure and to the record holder, as it must. It is statistical classification only, it does not assign any reader’s code, settle a principal activity, or decide a registration, and those formal matters rest with the national statistical institute or business register that holds the record.
