Augmented Human Development Index
What you should know about this indicator
- Each of the dimensions of the AHDI is measured with four indicators: a long and healthy life is measured by life expectancy at birth, knowledge is measured by mean years of schooling; a decent standard of living is measured by GDP per capita, logarithmized to reflect that incomes become less important as they increase; and civil and political freedom is measured by Varieties of Democracy's Liberal democracy index.
- The index is then calculated by normalizing the indicators. First, the indicators are brought onto the same scale, ranging from 0 to 1. This is done by setting minimum and maximum values for each indicator, and a country at or below the minimum value receiving a score of 0, and a country at or above the maximum value receiving a score of 1.
- The minimum and maximum values for each indicator are defined as follows: Life expectancy at birth ranges between 20 and 85 years; mean years of schooling, between 0 and 15 years; GDP per capita between 100 and 47,000 international-$ at 1990 prices; and V-Dem's Liberal democracy index is already standardized between 0 and 1 (most democratic).
- The AHDI is then estimated as the geometric mean of these indices, or AHDI = (Health index * Education index * Income index * Freedom index)^(1/4).

How we process data at Our World in Data
All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.
