This paper presents best practices for gender budgeting in OECD countries, consisting of the core features common to successful implementation of gender budgeting. These best practices identify elements that contribute to the sustainability of gender budgeting and help governments ensure that the budget helps achieve broader government objectives relating to gender equality, such as women’s participation in the labour market. The best practices draw on gender budgeting practices in Member countries and the OECD’s work with countries in designing and implementing gender budgeting.
