Methodology

The Social Institutions and Gender Index (SIGI) is a composite measure of gender equality, based on the OECD’s Gender, Institutions and Development Database. The 2012 SIGI has been developed by the OECD Development Centre, building on the 2009 SIGI. The development of the 2012 SIGI has involved several stages which have taken place between 2010 and 2012, set out in the diagram below. Each stage set out in the diagram below has taken place with consultation and input from key gender, development and statistical experts.

The 2009 version of the SIGI was developed in collaboration with a research team from Göttingen University under the leadership of Prof. Stephan Klasen. Valuable input and validation of our findings were equally provided by Geske Dijkstra and her team at Erasmus University Rotterdam.

Further detail on the 2012 SIGI methodology can be found below.
