The sex-specific demographic projections for 2021 show a male-to-female ratio almost equal to 1, with 50.4% of men compared to 49.6% of women, and this ratio is projected to be constant until 2050.  [1] This almost equitable proportionality in the human resource available for development requires that strategic planning and public policy formulation consider gender-specific data and gender-disaggregated indicators, with a view to supporting participatory and, therefore, sustainable development. However, the barriers are enormous and one of the main ones to effective integration of gender indicators into international public policies is the lack of evidence and gender-specific indicators relating to different development sectors. 

International policy-making mechanisms are based first and fore on the evidence to develop them. Thus, without gender-specific data, it is difficult to fully measure the progress made in achieving the Sustainable Development Goals (SDGs). Without data, it is difficult to make effective analytical assessments of the comparative situation of women and men in the world. In the absence of data on the different areas of development, including health, education, cultural inclusion and language promotion or agriculture, no informed policy can be effectively developed. In the absence of a clear identification of the needs of populations in a standardized database, and following a pygmalion effect, these needs will not be taken into account and planning decisions will be biased, hindering, the achievement of the SDGs. Ensuring that gender equality counts, through the collection, analysis and dissemination of sex-specific data is one of the major development challenges and AID wishes to contribute to this.
