I have reviewed inequality measures; explored and introduced a new methodology that reflects inequality and generates decile data and an index of the vast majority for the three components of the human development index of the population in eight countries: the USA (2019), Indonesia (2017), Burkina Faso (2014), Colombia (2018), South Africa (2016), Mozambique (2015), Zambia (2018) and Morocco (2014).
I used this decile data to calculate the bottom 70 and 80 percent for the three components of the HDI, namely health, education and income; the bottom 70 and 80 percent of the three indices; and the vast majority index for each of eight sample countries.
I refer to the 80 percent measure as the Vast Majority Human Development Index (VM-HDI).
I analyze the results to see how this new measure, VM-HDI related to the traditional UNDP HDI and discuss the main implication that can be drawn from these empirical results.
Overall, I find a more in-depth picture of inequality lived by the vast majority, in terms of health, education and income between the 80 and the top 20 percent.
I also illustrate a comparison of the VM-HDI by other types of adjusted HDI measures mainly the Sen Index.
