Can rapid population growth be good for economic development? When some of us were born inthere were two Europeans for every African; by the time we may retire inthere will be two Africans for every European. The population has doubled over the last 25 years, to about 40 million people, and rapid population growth is set to continue.
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.Abstract.
Throughout history, the expansion of human population has been supported by a steady growth in our use of high-quality exosomatic energy. Internet World Stats, Population and Internet Users in all countries and usage in all regions of the world. The Internet Big Picture. Internet World Stats.

Research highlights The prevalence of intellectual disability across the world is around 1%.
The prevalence is almost two times more in low and middle income countries compared to high income countries. Highest prevalence was seen in child and adolescent population. Using standardized diagnostic instruments and disability measurements leads to lower estimates compared to simple .
The % rise in vehicles last year was the largest percentage increase since , while the million year-to-year unit increase was the second-biggest gain in overall volume ever. The following plot is a rough estimate of world population from the time of the Flood of Noah, until the birth of Jesus, (53 generations).
For discussion purposes the population at the time of Abraham, eleven generations after the Flood, has been taken to be one million people.
