Why Was Division 45 Removed in ISIC Rev. 5?

In ISIC Rev. 5, published by the UN Statistics Division, the former Rev. 4 Division 45, which grouped trade in motor vehicles and motorcycles with their repair, was removed as a division. Trade and repair were placed where they now fit better in the structure. The removal was a restructuring, not a claim that motor vehicle trade or repair stopped being economic activity.

What Kind of Division Was Division 45 in Rev. 4?

Rev. 4 Division 45 combined selling vehicles with repairing them, even though selling and repairing are different kinds of work. It grouped trade in motor vehicles and motorcycles with their repair, under a single divisional umbrella organised around the vehicle. That organisation made sense as a way of gathering everything vehicle related in one place, and it made vehicle statistics easy to find in one corner of the old structure. It also hid a basic difference, because a sale transfers ownership while a repair restores an item that stays with its owner.

A garage that only repairs cars and a showroom that only sells cars were grouped together under the old division, despite doing different work all day. The garage diagnosed faults, replaced worn parts, and returned vehicles in working order. The showroom displayed stock, agreed prices, and transferred vehicles to new owners. Their customers, their skills, and their daily rhythms differed, yet the old division treated vehicle involvement as the organising fact. Rev. 5 questioned that organising fact, and decided that the kind of work should organise the structure more strongly than the kind of vehicle.

How Did Rev. 5 Rehouse Trade and Repair Separately?

Rev. 5 places trade with other trade in Section G, so vehicle selling sits alongside wholesale and retail trade more generally. A showroom selling cars to households is now read as retail trade, and a distributor selling vehicles onward to dealers is now read as wholesale trade, with detailed headings inside Section G separating those roles. Vehicle selling has not disappeared. It has been rehoused with other selling, where its wholesale or retail character and its goods can be described in the same framework as other trade.

Repair moves to a repair section, which groups repair work across product types rather than by vehicle alone. In Rev. 5, vehicle repair sits in Division 95 in Section T, alongside other repair services. That move may feel like a loss of visibility for vehicle repair, because it no longer sits beside vehicle trade. In structural terms, it is a gain in coherence, because repair work is now grouped with repair work, and trade work is now grouped with trade work, instead of both being grouped by the vehicle they touch.

Why Does a Restructuring Like This Happen at All?

Classifications are revised when the old arrangement stops matching how work is organised in practice. Selling and repairing have grown apart as activities, with different business models, different skills, and different data needs. Keeping them together under a vehicle umbrella made cross product comparisons harder, because vehicle repair could not easily be compared with other repair, and vehicle trade could not easily be compared with other trade. Splitting them lets each family be compared with its true neighbours, and lets statistics about trade and statistics about repair each tell a cleaner story.

The removal does not erase history. Older statistics coded under Rev. 4 Division 45 need a mapping to Rev. 5, and that mapping is described in a companion guide in this cluster. A reader comparing old and new series should therefore look for correspondence material, and should not assume that a Rev. 4 Division 45 total equals a simple sum of new headings without checking how the old total was split. The old total mixed trade and repair, so any new comparison must account for that mixture explicitly.

What Should a Reader Watch For After the Removal?

Division 45 was removed because its vehicle umbrella hid a work difference that Rev. 5 chose to make visible. This guide describes that choice as statistical classification background only, and it does not decide any reader’s code, principal activity, or registration. Where a formal heading is at stake, the work should be compared with the UNSD Rev. 5 descriptions and confirmed with the national statistical institute or business register that holds the record.
