Human Development & Quality of Life in Bulgaria
HDI 0.845 · UNDP rank 55 · latest published data
In UNDP's 2023 index data, Bulgaria has HDI 0.845 and rank 55, which corresponds to very high human development. That rank is only the starting point. Gender development sits close to parity on the GDI measure at 1.000 (UNDP group 1). In a different dimension, planetary pressures reduce the adjusted index to 0.740, a 12.4% change from HDI.
What sits inside Bulgaria's HDI
The 2023 HDI profile for Bulgaria rests on life expectancy of 75.6, schooling measures of 15.3 expected years and 11.5 mean years, plus GNI per capita of $32,175 in 2021 PPP dollars. The page keeps those components visible so the composite index is not read in isolation. When looking across the UNDP tables, keep missing fields explicitly missing before drawing conclusions from small differences.
Inequality changes the headline
Bulgaria's IHDI adjusts the headline index for inequality in health, education and income outcomes. It describes distribution, so it is not used here as a quality-of-life rating.
Gender and planetary-pressure adjustments
Bulgaria's complementary UNDP indicators include GDI 1.000, GII 0.208, PHDI 0.740. Reading them together is useful, but combining them would obscure their different definitions.
Quality-of-life coverage is conditional
No comparable OECD life-satisfaction observation is published on this page for Bulgaria. No value is inferred when the underlying source does not publish one.
What Bulgaria's numbers say together
Taken alongside HDI, Bulgaria's profile includes IHDI 0.748 with a 11.5% loss; PHDI 0.740 after a 12.4% adjustment; GDI 1.000. They are related indicators, but they should not be combined into one country score.
For this comparison, the headline UNDP result for Bulgaria is HDI 0.845, rank 55, for 2023. Broader quality-of-life indicators remain outside that index. For the evidence on this page, avoid blending different source vintages because the evidence is strongest when each metric keeps its own scope.
The IHDI is 0.748, and UNDP reports an overall loss of 11.5% relative to the headline index.
The GDI value is 1.000 in group 1; it should be read alongside, not merged into, HDI.
The PHDI is 0.740, with a 12.4% adjustment from the HDI value in UNDP's 2023 table.
Frequently asked questions
What is Bulgaria's HDI?
For Bulgaria, the 2025 UNDP report publishes a 2023 HDI value of 0.845 and rank 55.
How does inequality affect Bulgaria's HDI?
Bulgaria's Inequality-adjusted HDI is 0.748. The published overall loss is 11.5% relative to HDI.
Why is there no life satisfaction score on this page?
Quality-of-life data for Bulgaria appear only when the page can tie the value to a comparable source and year. For the profile as a whole, use the UNDP definition rather than a proxy so the page stays faithful to the published evidence.
Is HDI the same as quality of life?
No. HDI is an objective development index based on health, education and income. Life satisfaction adds a different perspective and is therefore not folded into HDI. When looking across the UNDP tables, keep unlike indices separate so the comparison remains traceable.
