What is World Population Prospects 2019? People, and thus populations, are at the centre of sustainable development. Each of the four global demographic “megatrends”– population growth, population ageing, migration and urbanization – holds important implications for economic and social development and for environmental sustainability. Timely and accurate population estimates and projections allow Governments to anticipate future demographic trends and to incorporate that information into development policies and planning. The 2019 revision of the World Population Prospects is the twenty-sixth edition of the United Nations population estimates and projections. It presents population estimates from 1950 to the present for 235 countries or areas, underpinned by analyses of historical demographic trends. This latest assessment considers the results of 1,690 national population censuses conducted between 1950 and 2018, as well as information from vital registration systems and from 2,700 nationally representative sample surveys. The 2019 revision also presents population projections to the year 2100 that reflect a range of plausible outcomes at the global, regional and country levels. The population estimates and projections presented in the World Population Prospects describe two of the four demographic megatrends (population growth and ageing), as well as key trends in human fertility, mortality, and net international migration that are integral to sustainable development. Collectively, these data constitute a critical piece of the evidence base for monitoring global progress towards the achievement of the Sustainable Development Goals by 2030. World Population Prospects 2019: • Confirms that the world’s population continues to grow, albeit at a slowing rate; • Points to the challenges facing some countries and regions related to rapid population growth driven by high fertility; • Notes that population size is decreasing in some countries due to sustained low fertility or emigration; • Underscores the opportunities available to countries where a recent decline in fertility is creating demographic conditions favourable for accelerated economic growth; • Highlights the unprecedented ageing of the world’s population; • Confirms the ongoing global increase in longevity and the narrowing gap between rich and poor countries, while also pointing to significant disparities in survival that persist across countries and regions; • Describes how international migration has become an important determinant of population growth and change in some parts of the world.

The report analyses the ways in which unpaid care work is recognized and organized, the extent and quality of care jobs and their impact on the well-being of individuals and society. A key focus of this report is the persistent gender inequalities in households and the labour market, which are inextricably linked with care work. These gender inequalities must be overcome to make care work decent and to ensure a future of decent work for both women and men.
The report contains a wealth of original data drawn from over 90 countries and details transformative policy measures in five main areas: care, macroeconomics, labour, social protection and migration. It also presents projections on the potential for decent care job creation offered by remedying current care work deficits and meeting the related targets of the Sustainable Development Goals.

Never before has inequality been so high on the agenda of policy-makers worldwide, or such a hot topic for social science research. More journal articles are being published on the topic of inequality and social justice today than ever before.
This is the Summary of the 2016 World Social Science Report. It draws on the insights of over 100 social scientists and other thought leaders from all over the world, across various disciplines, to emphasize transformative responses to inequality at all levels, from the grass-roots to global governance.
It concludes that:
- unchecked inequality could jeopardize the sustainability of economies, societies and communities;
- inequalities should not just be understood and tackled in terms of income and wealth: they are economic, political, social, cultural, environmental, spatial and knowledge-based;
- the links and intersections between inequalities need to be better understood to create fairer societies;
- a step change towards a research agenda that is interdisciplinary, multiscale and globally inclusive is needed to inform pathways toward greater equality.

In short, too many countries are investing too little in researching the long-term impact of inequality on the sustainability of their economies, societies and communities. Unless we address this urgently, inequalities will make the cross-cutting ambition of the Sustainable Development Goals (SDGs) to ‘leave no one behind’ by 2030 an empty slogan.

The World Social Science Report 2016 was prepared by the International Social Science Council (ISSC) and the Institute of Development Studies (IDS), and is co-published with UNESCO.
