exploring the institutional drivers of gender bias
using the Social Institutions and Gender index (SIGI)
Use slider to assign weights to SIGI components
SIGI Component 1
Use income levels to filter countries on chart
  1. Each of the four components of the index is assigned a uniform weight of 25% in the original calculation.
  2. Higher SIGI values indicate higher inequality: the SIGI ranges from 0% for no discrimination to 100% for very high discrimination. The SIGI was first launched in 2009, and then updated in 2012 and 2014. The fourth edition of the SIGI was launched in December 2018.
  3. The user defined value of SIGI is calculated using the weights chosen by the user with the slider. The original formula is then used with the user-defined weights (instead of 25% assigned to each component in the original). In the chart, initially all countries are along the diagonal as both the original and user-defined weights for the SIGI components are the same. As the user changes the weights, the countries move up or down the diagonal depending on the final SIGI value being higher or lower than the original.
