Production, deliveries and registrations: different counts

Choose the measure

OICA maintains distinct production and sales datasets. Its statistical definitions address sales and registration reporting, including their different timing. Keep the source’s terminology when using a figure rather than relabelling every vehicle count as customer sales.

Work through an imaginary dataset

Company A reports 80,000 units for a full year across a group. Company B reports 25,000 units for one brand during one quarter. Without matching the business boundary and period, a chart of those values tells us little about relative market position. All figures here are invented solely to illustrate the problem.

A good table records the business population, territory, period, unit and definition next to the total. If one source lacks a detail, keep an explicit gap. Do not fill it by borrowing a definition from an unrelated report.

Do not turn a count into a different claim

A volume ranking does not on its own measure satisfaction, reliability or service quality. Those questions require evidence designed for those outcomes. In the same way, a positive review is a description of one review experience unless its method establishes a broader sample.

Car-culture stories need a similar discipline. A public appearance with a vehicle can be described as an appearance. Establishing personal ownership or an endorsement requires additional evidence. Neither a celebrity story nor a sales chart should quietly become a product-quality score.

Make revisions traceable

Save the publication date and link with a figure. If the source later revises the dataset, readers can understand why a reported total changed. Clear definitions and traceable updates are the foundations of useful industry reporting.
