 As time passes, and these measures (the GDI and the GEM) are applied year after year, debate has arisen over whether or not they have been as influential in promoting gender-sensitive development as was hoped when they were first created.Some of the major criticisms of both measures includes that they are highly specialized and difficult to interpret, often misinterpreted, suffer from large data gaps, do not provide accurate comparisons across countries, and try to combine too many development factors into a single measure.The concern then arises that if these indices are not well informed, then their numbers might hide more than they reveal.
