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.

What are the objectives of the dataset?
The Social Institutions and Gender Index (SIGI) is an index designed to measure gender equality in a society. SIGI is a composite index of gender equality. It focuses on formal and informal social institutions that impact the roles of men and women, such as a society's norms, values and attitudes that relate to women. The variables span all stages of a woman’s life in order to show how discriminatory social institutions can interlock and bind them into cycles of poverty and disempowerment.
What is the methodology?
Higher values of the SIGI denote higher level of gender-based discrimination in formal and informal social institutions. The SIGI includes 27 variables combined into 16 indicators and 4 dimensions. The 27 variables include:
- 14 categorical variables describing the level of discrimination in legal frameworks (for all SIGI indicators but two: missing women and FGM) – these variables are based on 144 questions out of the 312 used to draft the SIGI country profiles;
-
3 attitudinal variables describing the level of discrimination in social norms; and
-
10 variables on prevalence rates describing the level of discrimination in practices.

What are the main results?
While assessing 180 countries overall, the SIGI ranks 120 countries for which full information over all the index sub-components is available. In order to assist the interpretation of the data and results, Countries are grouped by level of discrimination in five categories, with higher values of the index reflecting higher levels of discrimination:
-
Very Low (SIGI ≤ 20%): According to SIGI 2019, currently 32 countries, representing 27% of the countries ranked, have very low levels of gender discrimination in social institutions;
-
Low (20% < SIGI ≤ 30%): 43 countries (36% of the countries ranked) have low levels of gender discrimination in social institutions;
-
Medium (30% < SIGI ≤ 40): 16 countries(13% of the countries ranked) have medium levels of gender discrimination in social institutions;
-
High (40%<SIGI ≤ 50%): 17 countries, representing 14% of the countries ranked;
-
Very High (SIGI>50%): 12 countries, representing 10% of the countries ranked.
Currently, 24% of the countries ranked in the SIGI 2019 - that is almost one country every four - show high or very high levels of gender discrimination in social institutions.

Does the existing evidence support

The authors argue that the evidence based on differences
across countries is of limited use for policy design because
it does not identify the causal link from inequality to

inequality-reducing policies are ineffective. In other
words, the lack of evidence of a causal link is not in

Promoting Gender Equity in the Democratic Process: women's Paths to Political Participation and Decisionmaking
How can women be integrated in processes of democratisation? The participation of women in political and economic processes is essential for democratic governance. The PROWID grants system supported activities such as lobbying and advocacy, skills development and developing institutions to further women's social and economic rights. This report looks at women's participation in political culture, civil society and government institutions. Importantly, it puts participation in the context of shifting gender (and other) roles and identities.
