UN Department of Economic and Social Affairs (DESA) Policy Briefs

This policy brief draws attention to the value of external audits to Governments’ efforts to leave no one behind. It highlights some impacts of audit reports on equity, equality and inclusion. It then presents observations and examples from a review of audit report recommendations, which can inform and guide Governments in strengthening their work in this area.

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.

Effective and transparent public financial management is crucial for building trust in public institutions and mobilizing and effectively spending additional resources for sustainable development. Supreme Audit Institutions (SAIs) provide critical information and evidence to inform assessments of the performance of national fiscal systems, including in relation to SDG implementation, and to enhance the effectiveness of fiscal systems for sustainable development.

In a context marked by declining trust in public institutions and reduced fiscal space in many countries, supreme audit institutions (SAIs) play a key role in strengthening transparency and accountability in public institutions. The mandates of SAIs are generally aimed at promoting the transparency, efficiency, effectiveness and accountability of the public sector and improving the performance of government institutions. Initially focused on government compliance and financial auditing, SAIs’ mandates have been expanded to assess the economy, efficiency and effectiveness of public spending and government performance. SAIs can use their mandate to assess government efforts to implement the Sustainable Development Goals (SDGs), complementing other accountability institutions and actors (such as parliaments, civil society and the media) and governments’ internal monitoring and evaluation systems. Before the adoption of the 2030 Agenda for Sustainable Development, the engagement of SAIs with internationally agreed development goals was limited. Since 2016, this has changed significantly. Individual SAIs at the national level and groups of SAIs working under the umbrella of the International Organization of Supreme Audit Institutions (INTOSAI) have engaged in supporting the implementation of the SDGs in various ways, including through conducting audits of progress on SDG targets or their national equivalents, as well as audits of national programmes supporting SDG implementation. This work has resulted in tangible impacts on national policies, programmes and institutional arrangements in support of the SDGs. This brief highlights how the work of SAIs is informing SDG implementation, follow up and review. It provides a brief overview of SAIs’ engagement with the SDGs. This is followed by a snapshot of the current work of SAIs on SDGs and of their impacts. Finally, it reflects on the role of SAIs in national SDG follow-up and review systems.

Converging crises such as the COVID-19 pandemic, the war in Ukraine, climate change and various conflicts, have become a defining challenge of our time. Crises that might have previously been contained within a specific geographic space are now propagated rapidly through globally interconnected systems and networks in areas such as economics, finance, the environment and health. This Policy Brief highlights the following: (a) converging crises have reversed and exposed the fragility of global SDG progress and imposed high costs on developing countries, (b) reducing inequality and poverty is critical to building resilience against the impact of shocks and crises, and (c) investment in the SDGs, particularly those that underpin social development, can help build resilience of developing countries to multiple crises, as seen in the case of the COVID-19 pandemic.

The rapid adoption of renewable energy technologies and the transition away from fossil fuels are vital for combating climate change. Achieving net-zero carbon dioxide (CO2) emissions by 2050 will require much faster deployment of clean energy technologies, including wind turbines, solar panels, electric vehicles (EVs) and battery storage systems. This shift is fueling a sharp rise in demand for critical energy transition minerals such as copper, cobalt, lithium, nickel, and rare earth elements, particularly as developing countries work to achieve universal energy access and diversify their economies. For instance, an onshore wind power plant requires nine times more mineral inputs than a gas-fired plant of the same capacity, while an EV needs six times more minerals than a conventional car. Additionally, the average mineral requirement for new power generation capacity increased by 50 per cent during the 2010s, driven by the growing share of renewables in total capacity additions. Against this backdrop, countries rich in critical mineral resources have an opportunity to unlock significant development benefits. These minerals can attract foreign and domestic investment, create jobs, and boost fiscal revenues, exports, and overall economic growth. However, quantifying the economic scale of the mining industry remains challenging, especially due to the volatility of mineral prices, which directly impact valuations.

Shocks and crises have become more frequent, intense and widespread in an interconnected world, affecting more people across the globe. Crises that might have previously remained relatively contained within a well-defined geographic region, are now propagated rapidly through globally interconnected systems and networks in areas such as economics, finance, the environment and health. The 2008 Global Financial Crisis is an example of how financial shocks spread through the interconnected balance sheets of financial institutions, causing havoc around the world. The COVID-19 pandemic also shows how national health systems were unable to absorb the effects of the virus, which spread quickly through a dense global transportation network before disrupting highly concentrated economic and financial networks and killing more than 7 million people. Looking toward the Second World Summit for Social Development in 2025, this policy brief focuses on explaining how shocks turn into crises and how national policies, supported by the international community, can help counter shocks, build resilience, and advance social development objectives, namely eradicating poverty, promoting full and productive employment, and fostering social inclusion in times of converging crises.

Understanding how population trends are likely to unfold in the short, medium and long terms is critical for achieving a more inclusive, prosperous and sustainable future as recognized in the Declaration on Future Generations. This policy brief provides an overview of some of the main findings of the recently released report, World Population Prospects 2024: Summary of Results (United Nations, 2024a) with the aim of helping countries prepare for population sizes, age structures and spatial distributions that may differ appreciably from those of their recent past.

The COVID-19 pandemic disrupted the working methods of public institutions. The urgency to respond in real time loosened institutional constraints and forced public agencies to be more agile and to experiment with alternative ways to operate, accelerating innovation. Beyond the implementation of buffer measures to maintain essential public services, the crisis provided opportunities for transformations in public administration that would have been challenging to pursue in “normal” times. Although this urgency presented risks of weakening the checks and balances essential for accountability, it also led to the discovery of more efficient and effective ways to deliver public services, and many of these may become the “new normal”. Nevertheless, it is not clear that the agile decision-making, experimentation and innovation observed during the pandemic will persist. This raises the question of how to foster innovation in public institutions in the absence of crises. To retain public trust, governments must demonstrate they can effectively handle systemic shocks; they must demonstrate capacity to foresee problems and address them proactively before they become crises. Governments can tap into the innovations developed during the pandemic to better serve their constituents and accelerate the implementation of the 2030 Agenda for Sustainable Development.

In the lead up to the 2023 Sustainable Development Goals (SDG) Summit (18-19 September, New York), the Secretary-General urged all Member States and stakeholders to present forward looking commitments to accelerate sustainable development in the coming years. A total of 39 Member States and 1 non-member observer state submitted 141 commitments via the SDG Summit Acceleration and Accountability Platform. This policy brief reviews these national commitments from the 2023 SDG Summit, focusing on how countries are translating the leaving no one behind (LNoB) concept into different policies across various country settings.

Population ageing is a global phenomenon, a shift towards an increasing share of older persons in the population. Even the least developed countries (LDCs) are beginning to experience the progressive ageing of their populations, and this process is expected to accelerate during the second half of the current century (United Nations, 2023). Despite its far-reaching consequences, the emergence of this trend in LDCs has attracted only limited attention from both national policymakers and the international community. Most LDCs are still early in the decades-long process of population ageing, which is a direct consequence of the demographic transition towards longer lives and smaller families. Population ageing begins with a slowdown in the growth of the younger population but eventually involves the rapid growth of the older population. Early in this process, countries have an opportunity to benefit from the demographic dividend – a faster rate of economic growth on a per capita basis due to an increasing share of the working age population (and thus a falling dependency ratio) caused by a sustained decline in the fertility level. Although temporary, this opportunity often lasts for several decades. It comes to an end once the older population begins to grow more rapidly, leading to a rising old-age dependency ratio. Preparing for population ageing in LDCs will be critical for achieving sustainable development and ensuring that no one is left behind. Maximizing the benefits from the demographic dividend will provide an opportunity for these countries to develop economically before their populations become much older. It is also consistent with a pledge of “working together to support the acceleration of the demographic transition, where relevant”, as agreed in the Doha Programme of Action for the Least Developed Countries for the Decade 2022–2031 (United Nations, 2022).

Ten years ago, the United Nations celebrated the International Year of Small Island Developing States (SIDS). In the same year, the SIDS Accelerated Modalities of Action (SAMOA) Pathway, an ambitious 10-year action plan for SIDS, was adopted at the Third International Conference on SIDS held in Apia, Samoa, in 2014. The SAMOA Pathway identifies critical linkages between population and development in island states, most notably in the areas of health, gender equality and women’s rights and on the role of migrants in enhancing development in their communities of origin. Many of these linkages are also highlighted in the Antigua and Barbuda Agenda for SIDS (ABAS), along with emerging demographic issues that present new challenges and opportunities for the sustainable development of SIDS.

With less than seven years left to the 2030 deadline, progress towards the Sustainable Development Goals (SDGs) has been limited. But, at the SDG Summit in September 2023, Member States of the United Nations committed to bold, ambitious, accelerated, just and transformative actions to achieve the 2030 Agenda for Sustainable Development. For Governments, strengthening relationships and earning public trust is pivotal to realizing the changes required for more sustainable and resilient societies. While the COVID-19 pandemic significantly hindered advancement towards the Goals, and in some cases reversed progress, it also sparked innovation and experimentation in public institutions and in the way they interact with one another and broader society from which lessons can be drawn to reinvigorate efforts.

Middle-income countries (MICs), defined in terms of gross national income per capita, are a large and heterogeneous group of countries that differ across a broad range of development indicators. Despite their differences, MICs have common aspirations and contend with similar challenges. The recent confluence of crises has caused severe setbacks that have compounded longer-term development bottlenecks. Many MICs require international support to address current and long-term challenges. Eligibility criteria that rely only on income per capita limit available support – including access to concessional finance – without accounting for MICs’ multidimensional development needs.

The latest estimates and projections of global population from the United Nations, indicate that China will soon cede its long-held status as the world’s most populous country. In April 2023, India’s population is expected to reach 1,425,775,850 people, matching and then surpassing the population of mainland China. India’s population is virtually certain to continue to grow for several decades. By contrast, China’s population reached its peak size recently and experienced a decline during 2022. Projections indicate that the size of the Chinese population will continue to fall and could drop below 1 billion before the end of the century. Taking account of future population trends in national development planning is essential for achieving the Sustainable Development Goals, in particular, those related to poverty, food security, health, education, gender equality, decent work, inequality, urbanization and the environment, and for ensuring that no one is left behind.

Languages are one of the most significant emblems of human diversity, revealing how we can perceive, relate to, and understand the world differently. Languages are vehicles of our cultures, collective memory and values. They are an essential component of our identities. Out of the 6,700 languages spoken worldwide, forty percent are in danger of disappearing. Indigenous Peoples make up less than 6 percent of the global population, yet they speak more than 4,000 of the world’s languages. Most of the languages that are under threat are Indigenous languages. This dilemma is human-made and is exacerbated by ongoing assimilationist policies, social pressure, demographic change and the emphasis on a homogeneous nation State model that shares one culture and one language. The loss of global language diversity has been greatly accelerated by colonization and globalization. Other significant factors in the erosion of Indigenous languages are the dispossession of lands, territories and resources; repression and assimilation; genocide and shrinking ageing communities in which language is not passed to next generations.

This Policy Brief examines how public institutions can more effectively engage youth and promote their participation in decision-making and public service delivery to build more inclusive and resilient societies. It first examines the challenges public institutions face in meaningfully engaging youth in decision-making and public service delivery, as well as the behaviors and characteristics of young people that can be relevant to policy dialogue and participation. It then explains how digital technologies can be harnessed to effectively engage young people in decision-making and delivering public services. Lastly, it provides a set of policy recommendations on how public institutions can overcome engagement challenges and build an enabling ecosystem for youth participation.

Old age disadvantage begins at birth. Much of the inequality between older persons has its roots in early life conditions. Without policies to prevent it, disadvantages reinforce one another through peoples’ lives, leading to large disparities among older adults. A life course perspective on ageing is critical to improving people’s health and well-being throughout the life course into old age. The onset and severity of disability – affecting either physical or mental health – profoundly impacts the lives of people and their families and incurs large economic and societal costs in terms of health care and caregiving needs. Disability is a key outcome of unequal ageing as it has been tied to both early life conditions, such as childhood poverty and later life risk factors, including health behaviors, occupation and chronic stress. Examining physical functional limitations as a measure of disability lends itself to cross-national comparisons of inequalities in health in old age as it measures difficulties that people face in carrying out tasks in their daily living, and does not depend on access to health care and medical professionals for diagnosis, as is the case for examining differences in the prevalence of diseases, such as diabetes or cardiovascular disease.

In recent decades, all regions of the world have seen substantial progress in life expectancy at birth, which was estimated to be at 72.8 years in 2019 compared with 64.2 years three decades ago. As importantly, life expectancy has increased at all ages such that a person at age 65 in 2019 was likely to live 6.2 years longer than in the early 1950s (United Nations, 2022). But life expectancy differs significantly across countries and within them. Inequalities in health and in life expectancy across countries have received attention from the international community, which recognized that such inequalities are unfair and beyond an individual’s control. Assessing country-level inequality in life expectancy is therefore useful to examine whether outcomes in countries with high increases in life expectancy differ by their social and health policies. For instance, reducing inequality in life expectancy across countries points to the role that health policies play in controlling a wide range of diseases responsible for disparities in child and maternal mortality.

People in almost all countries are living longer. Globally, babies born in 2022 are expected to live 71.7 years on average, 25 years longer than those born in 1950. Rapidly ageing populations have increasing health and long-term care needs. As the forthcoming World Social Report 2023 discusses, however, today’s care and support systems for older persons are insufficient, requiring greater policy attention. The Covid-19 pandemic exposed existing weaknesses across countries in approaches to long-term care and showed how these weaknesses can aggravate inequalities. Poor quality and underfunded care facilities, insufficient provisions for care at home, low wages and precarious working conditions for paid care workers all contributed to increasing the already significant threat of Covid-19 for older persons (United Nations, 2020). The speed of change and the scale of the crisis have strengthened the call for fundamental reform of approaches to long-term care. Failure to do so will harm today’s older persons and those who care for them, as well as future generations of older persons.

Achieving the transition to an environmentally sustainable and climate-safe future is a matter of justice in itself—people in vulnerable situations, poor countries and future generations stand to suffer the most from climate change and environmental degradation—but how it is done also matters. A green transition is already taking place, creating jobs and economic opportunities, and its potential in the medium—and long-term is much greater. Inevitably, however, a transformation on the scale necessary to contain climate change also implies losses of jobs, livelihoods, and public and private revenues in many areas and not necessarily where the benefits will accrue most directly. It also entails changes in the way energy and food needs are met and land is used, generating other types of social and environmental challenges. Breaking the inertial high-carbon development paths requires strong political support worldwide and at all levels. Greening strategies that do not take into account the political economy of the transition and the economic and social well-being of affected communities are therefore likely to be politically fragile and vulnerable to stalemates and reversals. In this context, calls for a just transition have been increasingly prominent in global, national and subnational policy circles.

Governments that consider risk in policymaking and successfully integrate risk management into their governance frameworks and development have a better record of DRR and resilience building. Climate change is already changing the frequency and intensity of natural hazards, as well as increasing the vulnerabilities of countries in special situations including Small Island Developing States (SIDS). Ensuring risk-informed governance for climate action requires citizen-centric approach through the whole-of-society and whole-of-government approaches including the leverage of government innovation and frontier technologies for DRR and resilience. Emerging trends globally show that there is a stark upsurge in the number of disasters in this century compared to the previous one. Over the past two decades, climate-related disasters have nearly doubled compared to the preceding twenty years, affecting more than 4 billion people.

SDG progress has been set back, and the outlook faces uncertainty given the cumulative and amplified impacts of the COVID-19 pandemic, the war in Ukraine and climate change. This brief examines the channels through which these three shocks are impacting the SDGs and their implications for the achievement of the 2030 Agenda for Sustainable Development through recurrent crises. COVID-19 is estimated to have caused nearly 15 million deaths globally and brought the economy and people’s lives to a standstill for long periods in many parts of the world. The pandemic and the containment measures to control it significantly slowed economic growth, increased unemployment, raised poverty and hunger, widened inequality, and caused additional adverse impacts on women and children in many countries around the world. With uneven access to vaccines and treatments, and the continuing emergence of new variants, the pandemic continues to exert a malign influence on sustainable development.

The market capitalization of cryptoassets and so-called “stablecoins” has fallen by over 50% since November 2021, with the drop over twice as sharp as that in the S&P 500. While they have been touted for their potential to increase the efficiency of financial transactions and to support financial inclusion, their high volatility and largely unregulated and quasianonymous nature has raised concerns over investor protection and financial integrity, and increasingly also financial stability and international spillovers. Some of these risks have materialized during the May 2022 market rout, lending new urgency to calls for enhanced regulation and supervision. Policy solutions include bringing cash- and asset-backed stablecoins under the regulatory umbrella, reviewing and updating regulations to safeguard financial stability and integrity and harness technology, strengthening cooperation across sectors and jurisdictions, and addressing underlying domestic macroeconomic and structural challenges.
