Despite the rise in mortality, population growth continued, albeit at a slower rate due to the impact of HIV. Malawi’s population projections for and are 50 million and million—these are 8 million and 23 million lower than the projections without the impact of HIV. The impact of HIV on mortality has, however, begun to decline.
The world population will reach a size, which compared to humanity’s history, will be extraordinary; if the UN projections are accurate (they have a good track record), the world population will have increased more than fold over the span of years. We are on the way to a new balance. The big global demographic transition that the world Cited by: 2.

Variant projections for sub-national population projections. Introduction. This paper and Excel workbook provide PPWG with a summary of the investigation carried out by the General Register Office for Scotland (GROS) on the feasibility of producing additional variant population projections for Scottish areas.
Get this from a library. Variant population projections: population projections by sex and age with varying fertility assumptions, for Great Britain, from mid [Great Britain. Government Actuary.; Great Britain.
Office of Population Censuses and Surveys.;]. variant projections were published – high and low migration variants. This was the first time a low migration variant projection had been produced for sub-national areas. There is a growing demand for further variants providing more in-depth analysis on the future population of Scottish areas.
For English and Northern Irish sub-national. Delay(10=1sec). PGRG Blog #5, November Nik Lomax University of Leeds. This week, the Office for National Statistics (ONS) released six extra variants for the based National Population Projections (NPPs).
The intention of these variants is to provide results from ‘particular, but not necessarily realistic’ assumptions which can be compared alongside the projection variants. assumptions, and a number of variants based on alternative assumptions. For the based set of Local Authority Population Variant population projections book four variants have been produced along with the principal projection for each authority.
Please see page 2 for more details. The results of these variant projections. Definition of projection variants. In addition to the medium-variant projection based on probabilistic methods which provide 80 and 95 per cent prediction intervals, the Revision includes nine different projection variants (see table below) that convey the sensitivity of the medium-variant projection to changes in the underlying assumptions.

Medium Population Projection High Population Projection Low Population Projection Scarcity Stress Relative Sufficiency Summary s a result of an unexpected recent slowing of population growth, the United Nations projects that world population will be smaller by million people in the year than it projected just three years ago.
The Revision of World Population Prospects is the twenty-sixth round of official United Nations population estimates and projections that have been prepared by the Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat.
The main results are presented in a series of Excel files displaying key demographic indicators for each UN development. Session VIII Projection outputs and variants 10 March Cheryl Sawyer, Lina Bassarsky Population Estimates and Projections Section Figure 4.
World population estimates – and world population projections (medium variant with 80% and 95% confidence intervals) – This figure showcases the global estimates and population projection projections through Population projections: results and brief analysis of five projection variants For the Curaçao population projections five variants are composed by making five different combinations from a set of two fertility assumptions, one mortality assumption and four migration assumptions.
Based on this, the UN Population Division expects world population, currently () at billion, to level out at or soon after the end of the 21 st Century at billion (the median line), assuming a continuing decrease in the global average fertility rate from births per woman during the – period to in –, according to the medium-variant projection.
For the based set of local authority population projections four variants have been produced along with the principal projection for each authority.
The results of these variant projections are presented and discussed in this release, with an emphasis on the period mid to mid VARIANT PROJECTION) 52 Table B1: Total Population by Sex and Age (5-year Age groups) and Year of Projection (Single years),Copperbelt Province (MEDIUM VARIANT PROJECTION) 53 Table B2: Vital Events and Rates by Year of Projection (Single years),Copperbelt Province (MEDIUM VARIANT PROJECTION).
More recently the UNPD has developed population projections toand while the uncertainty in the underlying assumptions grows over time, population growth for the world and in many countries continues well beyond In fact, in all of the current population projections except the Low Variant, world population continues to grow past Projected world population by level of education; Projection of the population un by world region; Projections of years population, Africa vs.
Rest of the World; Projections of the Number of Children per Woman by education scenario; Projections of the Total Population by education scenario. For example, in the principal projection the population is projected to grow by 11% from mid, reaching million by mid In the high population variant, growth is projected to be percentage points higher than in the principal, with the population expected.
This dataset provides population projections for local authorities in Wales by gender, single year of age and each year from the base year ofthrough the projection period to This is the fifth set of population projections published for the 22 local authorities in Wales.
The variant projections use the same geographies and boundaries as the based subnational principal population projection. They do not incorporate any change made after Variant household projections based on the based variant subnational population projections will be released on 16 May Back to table of contents.Figure 2.

That is why population projections cannot be treated as precise forecasts. This box reviews the sources of errors in past official projections.a Chart A below shows how the principal population projections have evolved over recent decades.
