I want to know the answer to the following question:
In what year did the Human Development Report introduce the IHDI?
All the background I'm provided with is that "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)."". Is that enough to answer the question?
