Human Development & Quality of Life in Tanzania
HDI 0.555 · UNDP rank 165 · latest published data
In UNDP's 2023 index data, Tanzania has HDI 0.555 and rank 165, which corresponds to medium human development. The page therefore does not stop at the composite. Education combines 8.6 expected years of schooling with 6.1 mean years already attained. It also keeps in view that the health component is anchored by life expectancy of 67.0 years.
What sits inside Tanzania's HDI
When reading this profile, Tanzania's 2023 HDI inputs include life expectancy of 67.0, expected schooling of 8.6, mean schooling of 6.1, and GNI per capita of $3,515 in 2021 PPP dollars. Together they explain the headline index without turning any single input into a separate ranking.
Inequality changes the headline
For Tanzania, IHDI asks how the HDI changes once unequal achievement across people is considered, the adjustment is about distribution rather than subjective well-being. When using this figure elsewhere, keep missing fields explicitly missing before using the result as a shorthand for lived experience.
Gender and planetary-pressure adjustments
For this comparison, Tanzania has additional UNDP measures of GDI 0.951, GII 0.504, PHDI 0.541. These measures remain distinct because they measure different aspects of development.
Quality-of-life coverage is conditional
The OECD comparison used here does not provide a life-satisfaction observation that this Tanzania page can reproduce. No value is inferred when the underlying source does not publish one.
What Tanzania's numbers say together
Tanzania's non-headline measures include IHDI 0.391 with a 29.5% loss; PHDI 0.541 after a 2.5% adjustment; GDI 0.951. Their scopes differ, which is why the page presents them side by side rather than blending them.
HDI for Tanzania stands at 0.555 in 2023, with UNDP rank 165. It is a development benchmark based on three dimensions, not an all-purpose national score.
The IHDI is 0.391, and UNDP reports an overall loss of 29.5% relative to the headline index.
The GDI value is 0.951 in group 2; it should be read alongside, not merged into, HDI.
The PHDI is 0.541, with a 2.5% adjustment from the HDI value in UNDP's 2023 table.
Frequently asked questions
What is Tanzania's HDI?
UNDP's Human Development Report 2025 gives Tanzania an HDI of 0.555 for 2023 and rank 165.
How does inequality affect Tanzania's HDI?
UNDP reports IHDI 0.391 for Tanzania, which is 29.5% below the headline HDI after inequality across the three dimensions is taken into account.
Why is there no life satisfaction score on this page?
For the current profile, a subjective well-being figure for Tanzania is published only when the source supplies a usable observation. No value is inferred when the underlying source does not publish one.
Is HDI the same as quality of life?
No. UNDP's HDI focuses on longevity, education and income. Subjective well-being is kept outside the HDI calculation. When the indicator is reused, avoid turning the indicator into a general country score instead of treating all development measures as interchangeable.
