Themes
Adolescents and Youth
Globally, the number of adolescents and young people is at an all-time high. While the number of young people has been declining in the more developed regions since it peaked around 1980, it has been increasing in the less developed regions and is expected to continue to grow over the next few decades.
Ageing
When fertility begins to decline from elevated levels, the population distribution by age changes. Initially, the reduction in fertility leads to an increase in the relative size of the population at working ages, creating a favourable age distribution that may help to accelerate economic growth per capita, resulting in a 鈥渄emographic dividend鈥�.
Capacity Development
The Population Division builds and strengthens national capacities to estimate and analyse population levels and trends and other demographic indicators for formulating and implementing national policies and programmes related to population and development.
Family Planning
The Programme of Action of the 1994 International Conference on Population and Development affirmed the basic right of couples and individuals to decide freely and responsibly the number and spacing of their children and to have the information, education and means to do so.
Fertility and Marriage
Continued high fertility in some countries and areas is the major driver of population growth, while in other countries and areas the decline of fertility to historically low levels propels changes in the age distribution, including the gradual ageing of the human population.
International Migration
It is widely recognized that migrants make a positive contribution to inclusive growth and sustainable development in countries of origin and destination.
Mortality
Reducing mortality, increasing life expectancy, and improving the health of populations are key objectives of the Programme of Action of the 1994 International Conference on Population and Development and the 2030 Agenda for Sustainable Development.
Population Policies
Well-designed government policies are critical for implementing the Programme of Action of the 1994 International Conference on Population and Development and for achieving the Sustainable Development Goals.
Population Trends
Timely and accurate information about changes in the size and characteristics of a country鈥檚 population is needed by national governments, the 麻豆APP, international organizations and civil society to formulate, implement and evaluate policies and programmes in almost all spheres of life.
Sustainable Development Goals
罢丑别听, adopted by the General Assembly in September 2015, provides an ambitious set of goals whose achievement will set humanity on a path towards sustainability.
Urbanization
The world is becoming increasingly urbanized. Today, more than half of the global population lives in urban areas, up from around one-third in 1950 and projected to increase聽to around two-thirds in 2050.
