Human Development & Quality of Life in the United Kingdom
HDI 0.946 · UNDP rank 13 · latest published data
In UNDP's 2023 index data, United Kingdom has HDI 0.946 and rank 13, which corresponds to very high human development. What makes the country profile more informative than the rank alone is that a separate life-satisfaction observation of 7.54/10 for 2021 is available, so experienced well-being can be shown without folding it into HDI. Separately, Education combines 17.8 expected years of schooling with 13.5 mean years already attained.
What sits inside United Kingdom's HDI
Within the UNDP framework, the UNDP inputs behind United Kingdom's HDI are 81.3 for life expectancy, 17.8 for expected years of schooling, 13.5 for mean years of schooling and $54,372 GNI per capita in 2021 PPP dollars. These figures show what sits behind the composite score.
Inequality changes the headline
IHDI reframes United Kingdom's HDI by accounting for unequal outcomes within the population. That is a different question from how satisfied people say they are with life.
Gender and planetary-pressure adjustments
For this profile, United Kingdom has additional UNDP measures of GDI 0.979, GII 0.083, PHDI 0.827. Their scopes differ, which is why the page presents them side by side rather than blending them.
A separate quality-of-life signal
For United Kingdom, the OECD series provides a comparable 2021 life-satisfaction value of 7.54/10. Life satisfaction adds a different perspective and is therefore not folded into HDI.
What United Kingdom's numbers say together
The supporting measures for the United Kingdom are IHDI 0.869 with a 8.1% loss; PHDI 0.827 after a 12.6% adjustment; GDI 0.979; life satisfaction 7.54/10 (2021). These measures remain distinct because they measure different aspects of development.
UNDP reports a 2023 HDI of 0.946 for the United Kingdom, with rank 13. That headline measure is useful for development comparison, but it is not a complete quality-of-life score.
The IHDI is 0.869, and UNDP reports an overall loss of 8.1% relative to the headline index.
The GDI value is 0.979 in group 1; it should be read alongside, not merged into, HDI.
United Kingdom's comparable life-satisfaction result is 7.54 out of 10 in 2021. Quality-of-life evidence is presented alongside HDI only when a comparable observation is available.
