ONS publishes a sampling error of 14.8% for this figure and asks that anything above 10% is treated as imprecise — too few people in this region answered the survey for this occupation. The figure is shown because it is the one ONS published, but it is not firm enough to rank Wales against anywhere else, so this page doesn't.
ONS doesn't measure “data engineer” as its own category. These figures are for the wider group “Programmers and software development professionals”, which includes this role alongside others. ONS measures programmers and software development professionals as one group - it separates neither specialism nor seniority.
