Strengths of using HDI (human development index)?

The GDP and HDI are 2 separate interests. HDI is a single number or factor used to exploit or describe what happens to a specific group of people with specific cirstances. Exp. a young girl gets married at the age of 15. By using HDI, a person may be able to give the norm for those females who marry at the age of 15. Questions to ask may be, how long will she survive, does she finish school, what is her income age different stages of her life, and so on. Another HDI would give you the positive rates for the same person. Length of life, those who complete college, do not give birth until later age and so on..... It is difficult to measure the human development or to keep a groups HDI in line with any ssubstanceccording to the GDP. Our world is far to concentrated on the stock market and the level of wealth. They can be used together as a number to show the cocompromisingffects of how each affects the other.
