When was hdi introduced

Once each of the individual indices have been calculated, they are aggregated to calculate the HDI. The HDI is calculated as the geometric mean equally-weighted of life expectancy, education, and GNI per capita, as follows:.

The education dimension is the arithmetic mean of the two education indices mean years of schooling and expected years of schooling. It provides an indexed measure across the same three dimensions: a long and healthy life, access to knowledge and a decent standard of living. They are:. The index for each dimension ranges between 0 and 1. However, if we look at changes through time, we see that although HIHD values are typically lower, they can change much more quickly since indices are derived non-linearly on a logarithmic scaling.

The three key dimensions are: 1 — A long and healthy life — measured by life expectancy. On all aspects Our World in Data offers research and data in dedicated entries: Here is the Our World in Data entry on life expectancy.
