Gender mainstreaming is the current international approach to promoting equality between women and men.It is based on the recognition that gender inequality operates at all levels and in all sectors of society, and thus needs to be addressed in the mainstream. It aims to ensure that women and men benefit equitably from all that society has to offer, and are equally empowered to affect its governance and decisions.The Gender Management System (GMS) is a holistic and system-wide approach to gender mainstreaming developed by the Commonwealth, for the use of governments in partnership with other stakeholders including civil society and the private sector. The GMS is a comprehensive network of structures, mechanisms and processes to enable governments and other organisations to contribute to gender equality through all policy-making, planning and activities.This Quick Guide has been produced to assist governments and other stakeholders using gender-sensitive indicators in the context of gender mainstreaming. It is an abridged version of the GMS publication Using Gender-Sensitive Indicators: A Reference Manual for Governments and Other Stakeholders.
