This is because it is hard to tell which indicator one has to use to measure development. For example, should you only focus on human development, GNP of the country, or equal participation in political participation?. From what I have read so far, the UNDP is focusing on the Human Development index to measure development which, according to me is not enough to measure development. For example, if you take a look at the 2006/2007 data, Myanmar is more developed than India and China, a country with gross human rights violation and almost no human Rights accountability is claimed to be more developed than countries like India.
So, I would say that finding the right indicator is a hard thing to do in this regard.
P.s, I am not Indian and there is no bias to my comment.
Some aspects like justice and freedom are hard to measure due to inconsistency of data based on human feelings which is hard to quantify. They are also subjective with no objective data involved.
