These are modelled estimates, not measurements.
No test was taken in any of these places. Each figure is an inference from Census 2021
composition — qualifications, occupation and household structure — and it describes
who lives in an area, not what any individual is capable of. The 90% interval is wide
(±6–7 points) and largely common across areas, so treat the ranking as the finding and the
absolute number as approximate.
