Human Development & Quality of Life in Slovenia
Human Development
Slovenia enters the 2025 UNDP report with a 2023 HDI of 0.931 and rank 21, within the very high human development group. More revealing for this profile, Education combines 17.5 expected years of schooling with 13.0 mean years already attained. At the same time, gender inequality is low on the GII scale at 0.042, with UNDP rank 14.
What sits inside Slovenia's HDI
Slovenia's HDI can be read through four underlying inputs for 2023: 81.6 life expectancy, 17.5 expected schooling, 13.0 mean schooling and GNI per capita of $46,361 in 2021 PPP dollars. The components are inputs to HDI, not independent country league tables.
Inequality changes the headline
For Slovenia, IHDI asks how the HDI changes once unequal achievement across people is considered, the adjustment is about distribution rather than subjective well-being.
Gender and planetary-pressure adjustments
Slovenia's complementary UNDP indicators include GDI 0.997, GII 0.042, PHDI 0.791. The indicators add context without becoming a single composite DigifyWorld rating. For the evidence on this page, do not substitute a different denominator so the number is not mistaken for another indicator.
A separate quality-of-life signal
The page can add a comparable subjective well-being result for Slovenia, 7.70/10 in 2023. Life satisfaction is shown only as a separate subjective well-being measure.
What Slovenia's numbers say together
Slovenia's additional indicators read as IHDI 0.885 with a 4.9% loss; PHDI 0.791 after a 15.0% adjustment; GDI 0.997; life satisfaction 7.70/10 (2023). They are related indicators, but they should not be combined into one country score.
For 2023, Slovenia records HDI 0.931 and rank 21 in the UNDP table. The result should be read as a composite of health, schooling and income outcomes.
The IHDI is 0.885, and UNDP reports an overall loss of 4.9% relative to the headline index.
The GDI value is 0.997 in group 1; it should be read alongside, not merged into, HDI.
The dated life-satisfaction observation used for Slovenia is 7.70/10 for 2023. Life satisfaction adds a different perspective and is therefore not folded into HDI.
