This is the final report of a joint three-year project (2004-2006) between Denmark, Finland, Iceland, Norway and Sweden. The finance ministries and ministries responsible for gender equality affairs in these countries have engaged in development work and, under the coordination of the Nordic Council of Ministers, have exchanged ideas and experience concerning the work of mainstreaming a gender equality perspective into the national budget and budgetary process in each country. The aim of the report is to present the knowledge and experience that the project has helped generate and to provide recommendations on how gender budgeting in central government administrations may be successfully accomplished.
