The infographic also highlights an important distinction between the volume of truck driver job postings and the composition of licence demand.
Support & waste services has the largest number of postings among the classified sectors shown, but its licence mix is relatively balanced between AZ and DZ. Transportation & Warehousing which is at the second spot in terms of job postings is much more heavily concentrated in AZ. Retail trade has fewer postings again yet displays one of the most diverse licence profiles.
In other words, a sector's contribution to truck driver hiring tells us how much demand is being advertised, while its licence distribution provides another layer of information about what that demand looks like.
That distinction can be useful when thinking about workforce development and training. Aggregate demand for “truck drivers” alone does not capture the differences visible in the job advertisements. Looking at licence requirements alongside sector provides a more detailed view of the qualifications employers are requesting.
Finally, the 2,723 additional truck driver postings that did not specify a licence type classifiable as AZ, DZ, AZ/DZ or G should not be overlooked.
Their exclusion from the licence-distribution calculations is analytical rather than an indication that these postings are unimportant. Without a licence requirement that can be classified into one of the four categories, they cannot reliably be assigned to AZ, DZ, AZ/DZ or G without making assumptions that are not supported by the postings.
This also places the infographic in the appropriate context: the licence analysis describes the 4,694 postings for which these requirements could be identified, rather than all 7,417 truck driver postings captured by JobsTO.
