The Social Institution and Gender Index (SIGI) dataset address the de jure and de facto situations of discriminatory social institutions, combining both qualitative and quantitative data providing information information on laws, attitudes and practices across 180 countries. According to the original SIGI website:
"Discriminatory social institutions intersect across all stages of girls’ and women’s life, restricting their access to justice, rights and empowerment opportunities and undermining their agency and decision-making authority over their life choices. As underlying drivers of gender inequalities, discriminatory social institutions perpetuate gender gaps in development areas, such as education, employment and health, and hinder progress towards rights-based social transformation that benefits both women and men."
The first edition of the SIGI dataset was first launched in 2009, and then updated in 2012, 2014 and 2019. The SIGI 2019 is built around four sub-indices, namely discrimination in the family, restricted physical integrity, restricted access to productive and financial resources, and restricted civil liberties.
