Three main measures of gender inequality are used in calculating gender equality and testing programs for the purposes of development aid. In the 1995 Human Development Report the United Nations Development Program introduced the Gender Development Index and Gender Empowerment Measure. The Gender Empowerment Measure is calculated based on three measures, proportion of women in national parliaments, percentage of women in economic decision making positions and female share of income. The Gender Development Index uses the Human Development Index and corrects its results in life expectancy, income, and education for gender imbalances. Due to criticisms of these two indexes the United Nations Development Program in its 2010 Human Development Report introduced the Gender Inequality Index. The Gender Inequality Index uses more metrics and attempts to show the losses from gender inequality. Even with these indexes, Ranjula Swain of the Stockholm School of Economics and Supriya Garikipati of the University of Liverpool found that, compared to the effectiveness of health, economic, and education targeted aid, foreign aid for gender equality remains understudied. Swain and Garikipati found in an analysis of Gender Equality Aid that on a country and region-wide level gender equality aid was not significant in its effect. Swain and Garikipati blame this on the relative lack of aid with gender equality as a primary motivation. In 2005, the Interagency Gender Working Group of the World Health Organization released the "So What? Report" on the effectiveness of gender mainstreaming in NGO reproductive health programs. The report found these programs effective, but had trouble finding clear gender outcomes because most programs did not measure this data. When gender outcomes were measured, the report found positive programmatic effects, but the report did not look at whether these results were from increased access to services or increasing gender equality. Even when gender equality is identified as a goal of aid, other factors will often be the primary focus of the aid. In some instances the nature of aid's gender equality component can fail to be implemented at the level of individual projects when it is a secondary aspect of a project. Gender equality is often put forward as a policy goal for the organization but program staff have differing commitment and training with regards to this goal. When gender equality is a secondary aspect, development aid which has funds required to impact gender equality can be used to meet quotas of women receiving
