Detailed explanation-1: -These indicators are compiled into a single number between 0 and 1.0, with 1.0 being the highest possible human development. HDI is divided into four tiers: very high human development (0.8-1.0), high human development (0.7-0.79), medium human development (0.55-.70), and low human development (below 0.55).

Detailed explanation-2: -The HDI is the geometric mean of normalized indices for each of the three dimensions. The health dimension is assessed by life expectancy at birth, the education dimension is measured by mean of years of schooling for adults aged 25 years and more and expected years of schooling for children of school entering age.

Detailed explanation-3: -India’s latest HDI value of 0.633 places the country in the medium human development category, lower than its value of 0.645 in the 2020 report. The report attributes the drop in HDI from 0.645 in 2019 to 0.633 in 2021 to India’s falling life expectancy-from 69.7 years to 67.2 years during the survey period.
