Regional salary rank is not regional living standard
A London salary can rank lower against other London jobs while still exceeding most UK salaries. Higher rent, commuting and childcare costs may then reduce the household advantage. The regional table is useful for labour-market benchmarking, but it cannot measure what remains after local costs.
Why the top end varies more
At the lower and middle parts of the distribution, salary thresholds are relatively compressed across much of the UK. London separates sharply at higher percentiles because it contains a greater concentration of senior roles in finance, law, technology and corporate management.
Place of work matters
The underlying regional statistics are based on workplace rather than home address. A commuter living in one region and working in another belongs to the work region for this comparison.
Nottingham example
A full-time salary of £50,000 is slightly above the 80th percentile for the East Midlands. The same salary sits only a little above the London median.
