 It is also often argued that the number of women in parliament isn't an adequate indication of gender empowerment progress in a given country because many times feminists are considered political liabilities, and as such, female politicians do not always promote female interests.On the other hand, however, information regarding the number of parliamentary seats held by women is very easy to obtain, and very hard to alter, making it one of the more reliable sources of data in the measure.Another criticism of the GEM is its failure to address the issue of female control over their bodies and sexuality, which some argue is an important source of female empowerment and as such should be included in the measure.
