Side by side, never added together

National government

The websites central governments run on hosts of their own. Each region’s population is its own cohort, drawn from that country’s own register and scored against the same Index. There is no figure across regions: it would be a number about whichever region has more sites.

Purple line is the median. Grey band is the middle half of the range. A population drawn from a different kind of register is not the same population: the UK’s schools are schools, where the US cohort is the districts that run them.
