Women over the age of 50 account for 27 per cent of the world’s women and yet they are almost entirely invisible within debates on gender equality. By the time women approach older age, many will have experienced a lifetime of inequality and discrimination, the impact of which will leave them poorer, in worse health, and feeling more acutely the impact of increasing global crises, including climate change. Despite this, older women continue to contribute to their families, communities and economies in multiple unpaid and paid roles. Providers of international aid finance have a critical role to play to ensure that action to achieve gender equality and women’s economic empowerment includes women of all ages. However, the analysis in this report show that this is far from the case. It reveals significant gaps in how older women’s rights and needs are being addressed through existing donor spending on gender equality. Cuts in aid budgets are already reported to be disproportionately affecting women, and gender equalityfocussed aid is under threat. It is more important than ever that aid focusing on gender equality and women’s empowerment addresses critical issues at every stage of life, targeting the specific needs and realities of women of all ages. As a result of this report, we want donors to better understand the issues facing older women, and take action to rebalance their investments in gender equality, ensuring that older women are fully included. With only a few years left to accelerate progress on the Sustainable Development Goals (SDGs), it is more urgent than ever to adopt an all-ages approach to gender equality and women’s economic empowerment, ensuring that no woman is left behind in global efforts to end poverty in all its forms. Older women’s economic rights and roles must be acknowledged and addressed through collective action to tackle inequality.
