UK Cognitive Atlas

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. How the number is built, and what it cannot tell you → ×
