Read this: The 2010 Human Development Report introduced an Inequality-adjusted Human Development Index (IHDI). While the simple HDI remains useful, it stated that "the IHDI is the actual level of human development (accounting for inequality)," and "the HDI can be viewed as an index of 'potential' human development (or the maximum IHDI that could be achieved if there were no inequality)."
Now answer this question, if there is an answer (If it cannot be answered, return "unanswerable"): Which measures the potential development, the HDI or the IHDI?
the HDI
