Human Capital Dilemma

How does one measure a country's stock of human capital ? (This is from one of my Linkedin answers)

If you were do define the measure of human capital, it would have made this question even more interesting.

1. If you want to go by NUMBER measure, you know how to do that.Just add all employable indian population.(again, you can set criteria for 'who is an employable indian')

2. If you want to know the VALUE measure of human capital, then add salaries of employed population. (You know, in a way this is an another way of calculating GDP of the country)

3. If you want to know the POTENTIAL VALUE measure of human capital, add salaries of employed and employable population.

4. If you want to know KNOWLEDGE value of all employable population, well, it would have been stupendous had i known this. The classification based on education levels should give a close answer but never a right answer.

Also realtive to this, you can check out more on HDI- Human development index. Ther are some cues you can take based on how HDI is calculated. But this is different from your HCM- Human capital measure.
