The current world population of 7.3 billion is expected to reach 8.5 billion by 2030, 9.7 billion in 2050 and 11.2 billion in 2100, according to a new UN DESA report, “World Population Prospects: The 2015 Revision”, launched today.

“Understanding the demographic changes that are likely to unfold over the coming years, as well as the challenges and opportunities that they present for achieving sustainable development, is key to the design and implementation of the new development agenda,” said Wu Hongbo, UN Under-Secretary-General for Economic and Social Affairs.

Most of the projected increase in the world’s population can be attributed to a short list of high-…

A new United Nations flagship report launched today finds that solutions to the challenges to people and planet must build on clear scientific findings in order to be sustainable. “The successful implementation of the new sustainable development agenda requires a strong scientific foundation that is understood by policymakers,” said Wu Hongbo, UN DESA’s Under-Secretary-General, referring to the proposed 17 sustainable development goals, scheduled for adoption in September in New York.

The 2015 Global Sustainable Development Report, an intergovernmental-mandated report on the science-policy interface for sustainable development, was presented to UN Member States at the High…

Calling for inclusive, agile and coordinated action to usher in an era of sustainable development for all, Secretary-General Ban Ki-moon on 4 December presented the UN General Assembly with an advance unedited version of his “synthesis report,” which will guide negotiations for a new global agenda centred on people and the planet, and underpinned by human rights. The report was formally issued in the six official UN languages on 31 December 2014.

“Next year, 2015, will herald an unprecedented opportunity to take far-reaching, long-overdue global action to secure our future well-being,” Mr. Ban said as he called on Member States to be “innovative,…

Targets for the Millennium Development Goals related to the global partnership to improve people’s lives and end poverty show mixed results on providing the poorest developing countries with greater access to aid, trade, debt relief, essential medicines and technologies, according to a new report launched today by United Nations Secretary-General Ban Ki-moon.

The lives of millions of people worldwide have improved due to concerted efforts – at the global, regional, national and local levels – to achieve the eight Millennium Development Goals (MDGs). Recent statistics show that with many MDG targets already met – including reducing poverty, increasing access to clean drinking…

Today, 54 per cent of the world’s population lives in urban areas, a proportion that is expected to increase to 66 per cent by 2050. Projections show that urbanization combined with the overall growth of the world’s population could add another 2.5 billion people to urban populations by 2050, with close to 90 percent of the increase concentrated in Asia and Africa, according to a new United Nations report launched today.

The 2014 revision of the World Urbanization Prospects by UN DESA’s Population Division notes that the largest urban growth will take place in India, China and Nigeria. These three countries will account for 37 per cent of the projected growth of the world’s urban…

World Population Policies 2013 report is part of a series that provides comprehensive and up-to-date available information on the population policy situations and trends for all 193 Member States, two Observer States and two non-member States of the United Nations. The publication documents changes in Government views and policies from 1976 to 2013 with respect to population size and growth, age structure, fertility, reproductive health and family planning, health and mortality, spatial distribution and internal migration, and international migration within the context of demographic, social and economic change.

The publication provides a coherent accounting framework of economic flows from one age group or generation to another, typically for a national population in a given calendar year. This manual presents the concepts, methods and estimation procedures to measure these flows over the life-cycle. The NTA estimates are useful to understand and analyse the implications of changing age structures for the fiscal sustainability of social programs, the accumulation of physical and human capital, economic growth, and familial support for children, youth and older persons.

National Transfer Accounts are consistent with the System of National Accounts (SNA), and provide measures by single…

The current world population of 7.2 billion is projected to increase by 1 billion over the next 12 years and reach 9.6 billion by 2050, according to a United Nations report launched today, which points out that growth will be mainly in developing countries, with more than half in Africa.

“Although population growth has slowed for the world as a whole, this report reminds us that some developing countries, especially in Africa, are still growing rapidly,” said the Under-Secretary-General for Economic and Social Affairs, Wu Hongbo in a press release on the report.

The report, World Population Prospects: the 2012 Revision, notes that the population of developed regions will…

Africa and Asia together will account for 86 per cent of all growth in the world’s urban population over the next four decades, adding that this unprecedented increase will pose new challenges in terms of jobs, housing and infrastructure. Africa’s urban population will increase from 414 million to over 1.2 billion by 2050 while that of Asia will soar from 1.9 billion to 3.3 billion, according to the 2011 Revision of the World Urbanization Prospects, produced by the UN Population Division of the Department of Economic and Social Affairs (DESA).

The largest increases in urban population are expected in the following countries: India, China, Nigeria, the United States and Indonesia…

The United Nations has updated a set of guidelines to prevent double taxation between countries, as well as to avoid tax evasion, which costs countries $3.1 trillion every year.

The UN Model Double Taxation Convention between Developed and Developing Countries (the UN Model) is used by countries as a basis for negotiation of their bilateral tax treaties.

Double tax treaties are agreements to prevent taxing income twice by allocating taxing rights over this income between two countries. These types of treaties play a key role in encouraging investment and technology transfer, while allowing governments to retain taxing rights over the money that comes from those investments…

UN Population Division's wall chart on Rural Population, Development and the Environment 2011 presents the latest data available for 15 indicators of rural population, land use, development and environment. It provides estimates at the national, regional and world levels, giving us a better understanding of the relationship between demographic dynamics, natural resources and cultural practices.

This report, published by the Population Division, is the third in the series of the analysis of reproductive behaviour worldwide. It discusses levels and trends of fertility, the timing of childbearing, marriage, contraceptive use and national policies with respect to fertility and childbearing for 196 countries or areas. The data presented are obtained from civil registration statistics, population censuses and nationally representative sample surveys.
