Will World population projection South rise again? 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. The "low-variant" scenario of population growth now foresees million more people on the planet in than it did two years ago.
The study predicts 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: Some of the authors of the UN report say that life expectancy is assumed to rise slowly and continuously.
But Haub said the observed increases in industrialized-world fertility rates will have a relatively minor effect overall - populations are expected to decline over time if average fertility rates remain below 2. The hypothetical feasibility and wide availability of life extension by technological means would further exacerbate the overpopulation problem.
Bysix countries are expected to exceed million: These children and young people are future workers and parents, who can help to build a brighter future for their countries.
Just like the other U. Sprawling capital city area is bound to keep growing. 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.
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. 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.
It will be a top 10 population locale in the United States, but it will hardly factor in the discussion on a global scale. 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.
That has now happened. A metro area with 5. While the "median-variant" scenario, often seen as "most likely," remains almost the same as before - predicting a world with 9.
We head back to the eastern seaboard for our next two U. This lower rate was a consequence of large proportions of women delaying pregnancy until later in their lives. A city in the Lone Star state shows up. In a biennial report released last week, the U. Despite the drastic increase, the Dallas-Fort Worth area, like the other big cities in the United States, is going to slip down the rankings on a global scale.
While significant differences in life expectancy across major areas and income groups are projected to continue, they are expected to diminish significantly by But bythe population of India is expected to surpass that of China.
Not only that, but the area remains a top destination for immigrants. The medium projection is 9. The high projection, however, foresees some 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.
World population projected to reach 9. A giant city could keep growing for years to come. The researchers used several mathematical models and arrived at different figures.
Another metro area in the northeast predicted to lose ground. The study projects the world population in to be 8.
Doing so would likely require an increase in the use of fertility drugs or another form of medical advance.The current world population of billion is expected to reach billion inbillion in and billion inaccording to a new United With roughly 83 million people being added to the world's population every year, the upward trend in population size is expected to continue, even assuming that fertility levels will continue to decline.
From to current year: elaboration of data by United Nations, Department of Economic and Social Affairs, Population Division.
World Population Prospects: The. rows · Projections of population growth established in predict that the human population is likely to keep growing untilreaching an estimated billion inbillion in and billion bywhile the 7.
The UN has issued multiple projections of future world population, based on different assumptions. From tothe UN consistently revised these projections downward, until the revision, issued on March 14,revised the mid-range estimate upwards by million. In a biennial report released last week, the U.N.
Population Division increased slightly a projection it uses to forecast the size of the human population. The "low-variant" scenario of population growth now foresees million more people on the planet in than it did two years ago. Economics and Statistics Administration U.S. CENSUS BUREAU U.S.
