Human Development & Quality of Life in Gabon
HDI 0.733 · UNDP rank 108 · latest published data
In UNDP's 2023 index data, Gabon has HDI 0.733 and rank 108, which corresponds to high human development. The headline needs context: The income component uses GNI per capita of $18,854 in 2021 PPP dollars. Another part of the dashboard shows that the GII reading of 0.505 (rank 135) is an important counterpoint to the aggregate HDI.
What sits inside Gabon's HDI
In this country profile, Gabon's health, education and income inputs are 68.3 life expectancy, 12.5 expected schooling, 9.7 mean schooling and $18,854 GNI per capita in 2021 PPP terms. They belong to the HDI calculation rather than separate DigifyWorld scores.
Inequality changes the headline
The inequality-adjusted measure for Gabon applies a distribution penalty to the same three HDI dimensions. It should therefore be read alongside HDI, not as a separate life-satisfaction score.
Gender and planetary-pressure adjustments
Beyond HDI, Gabon's UNDP profile also reports GDI 0.994, GII 0.505, PHDI 0.704. Each measure has a different definition, so they are not combined.
Quality-of-life coverage is conditional
This profile does not show a verified comparable life-satisfaction value for Gabon. A missing source value is shown as unavailable. When using this figure elsewhere, avoid turning the indicator into a general country score because a composite score cannot explain every outcome on its own.
What Gabon's numbers say together
Gabon's non-headline measures include IHDI 0.558 with a 23.9% loss; PHDI 0.704 after a 4.0% adjustment; GDI 0.994. They are related indicators, but they should not be combined into one country score.
UNDP reports a 2023 HDI of 0.733 for Gabon, with rank 108. That headline measure is useful for development comparison, but it is not a complete quality-of-life score. For the profile as a whole, preserve the distinction between level and distribution before using the result as a shorthand for lived experience.
The IHDI is 0.558, and UNDP reports an overall loss of 23.9% relative to the headline index.
The GDI value is 0.994 in group 1; it should be read alongside, not merged into, HDI.
The PHDI is 0.704, with a 4.0% adjustment from the HDI value in UNDP's 2023 table.
