World population projected to reach 9. But bythe population of India is expected to surpass that of China. Consequently, the population of Nigeria is projected to surpass that of the United States by aboutat which point it would become the third largest country in the world.
Bysix countries are expected to exceed million: During this period, the populations of 28 African countries are projected to more than double, and byten African countries are projected to have increased by at least a factor of five: Slower world population growth due to lower fertility rates Future population growth is highly dependent on the path that future fertility will take, as relatively small changes in fertility behaviour, when projected over decades, can generate large differences in total population.
In recent years, fertility has declined in virtually all areas of the world, even in Africa where fertility levels remain the highest of any major area.
Ageing population growing rapidly The slowdown in population growth, due to the overall reduction in fertility, causes the proportion of older persons to increase over time. Globally the number of persons aged 60 or above is expected to more than double by and more than triple by Higher life expectancy and the contribution of the Millennium Development Goals MDGs Life expectancy at birth has increased significantly in the least developed countries in recent years.
The six-year average gain in life expectancy among the poorest countries, from 56 years in to 62 years inis roughly double the increase recorded for the rest of the world. While significant differences in life expectancy across major areas and income groups are projected to continue, they are expected to diminish significantly by Progress in reducing under-five mortality, one of the MDG targets, has been very significant and wide-reaching in recent years.
Populations in many parts of the world are still young, creating an opportunity for countries to capture a demographic dividend Populations in many regions are still young. In total, these three regions are home to 1.
These children and young people are future workers and parents, who can help to build a brighter future for their countries. Providing them with health care, education and employment opportunities, particularly in the poorest countries and groups, will be a critical focus of the new sustainable development agenda.1 The Elephant in the Room: Population and Economic Growth Discourse in Ethiopia Tsegaye Tegenu October 27, The world’s 7 .
The chart below shows that global population growth reached a peak in and with an annual growth rate of %; but since then, world population growth was halved.
For the last half-century we have lived in a world in which the population growth rate has been declining. In , an analysis of United Nations data by the journal Science concluded that a halt to population growth in this century was unlikely and projected that between bn and bn people would be living on the planet by The Human Population.
Take a minute and think about all of the different people you interact with in a given day. For most people, this would include family, friends, co-workers, and strangers. The demographic analysis of labor markets can be used to show slow population growth, population aging, and the increased importance of immigration.
