(3) I income: Index of GNI per capita (PPP - USD)

The sub-indices are calculated as follows:
Actual value - Minimum value
Dimension index =
Maximum value - Minimum value

In particular, I income is calculated using the folular below:
ln (real) - ln (min)
I income =
ln (max) - ln (min)

The value Max and Min of relevant indicators, which are used to
calculate Vietnam’s HDI, is based on Human Development Report 2020

of UNDP:

Index Unit Max Min

Average life expectancy at birth Year 85,0 20,0

Mean years of schooling Year 15,0 0,0

Expected years of schooling Year 18,0 0,0
