UN DESA Policy Brief No. 180: Anticipating the extent and pace of population ageing in SIDS can help build a more sustainable future in these vulnerable states
Over the next decades, most small island developing States (SIDS) are projected to experience a rapid increase in both the share and the number of people aged 65 years or over. In half of the SIDS, the size of the older population will double between now and 2055. All SIDS, even those with youthful populations today, should embrace forward-looking strategies to capitalize on the opportunities that population ageing will bring, while also addressing the context-specific challenges it may pose.
UN DESA Policy Brief No. 179: From the First to the Second World Summit for Social Development: reclaiming a broad vision of social progress
The World Social Report 2025 warns that piecemeal approaches are no match for the scale and interconnectedness of today’s challenges. Rising economic insecurity, persistent inequality, eroding trust, and social fragmentation demand coordinated responses grounded in a shared commitment to equality, social justice, and solidarity. The 2025 World Summit for Social Development offers a chance to reaffirm the Copenhagen Declaration and reapply its principles to current realities, restoring a holistic vision of social progress as the foundation of a more inclusive, resilient, and sustainable future.
UN DESA Policy Brief No. 178: Assessing group-based inequalities across the life course for a more inclusive world
While there has been progress in promoting opportunities for all since the 1990s, group-based inequalities persist, including during childhood. Gaps between groups are not closing fast enough; the goal of leaving no one behind is likely to remain out of reach by 2030. This brief illustrates how inequality in opportunity between different population groups can be quantified using existing household survey data, drawing on analysis conducted for the 2025 edition of the World Social Report.
UN DESA Policy Brief No. 171: Leveraging Critical Energy Transition Minerals: policy pathways for sustainable development
Developing countries with extensive critical energy transition mineral reserves have the potential to harness these resources for economic growth and sustainable development. However, doing so involves significant economic, environmental and social risks. Strong governance, strategic national policies and effective international cooperation are essential to maximize sustainable development benefits and avoid the so-called resource curse.
