Inequality in life expectancy
What you should know about this indicator
- This metric is needed to estimate the Inequality-adjusted Human Development Index.
- This version of the Atkinson index uses an inequality aversion parameter ε equal to 1. The parameter defines how sensitive the index is to changes in the lower end of the distribution. In this form, the inequality measure is A = 1 - g/μ, where g is the geometric mean and μ is the arithmetic mean of the distribution.

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.
At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.
Notes on our processing step for this indicator
We calculated averages over continents and income groups by taking the population-weighted average of the countries in each group. If less than 80% of countries in an area report data for a given year, we do not calculate the average for that area.
