If you want to see more on how Africa is changing have a look at our slide show at AfricaInData.org. … while many of the cities with low shares of young people were in Germany or Romania. The big global demographic transition that the world entered more than two centuries ago is then coming to an end: This new equilibrium is different from the one in the past when it was the very high mortality that kept population growth in check. In Global Environmental Change Volume 42, January 2017, Pages 181–192. The projections – made by the UN’s Population Division – suggest that by 2027, India will surpass China to become the world’s most populous country. China has been the world’s most populous country for a long time: back in 1750, it had a population of 225 million, around 28% of the world population.6. 2017 Jan; 42: 181–192. The line chart shows the same data, but also includes the UN projection until the end of the century.
The classification by degree of urbanisation is based on identifying urban centres (high population density), urban clusters (moderate population density) and rural cells starting from 1 km² population grid cells. In comparing 1950 and 2018 we see that the number of children born has increased – 97 million in 1950 to 143 million today – and that the mortality of children decreased at the same time. This then allows comparisons of how education matters for the size and distribution of the future population of the planet. All future projections of global population are uncertain. Extreme poverty, for example, is expected to become increasingly concentrated in Africa in the decades which follow. The width represents the size of the population of a given age; women on the right and men to the left. In Luxembourg, the employment rate for cities was 6.8 pp higher than for either of the other two degrees of urbanisation, while in Croatia, Lithuania and Romania the difference was also more than 5.0 pp. It comes to an end when the average number of births per woman – the fertility rate – declines. The number of residents living in the commuting zone around the Spanish capital of Madrid also grew at a rapid pace, up by 9.8 % overall between 2010 and 2018 (note that the time interval is shorter than for Roma); this was in stark contrast to the situation within the city boundaries, where the number of residents fell by 1.5 %. Budapest in Hungary was the only functional urban area from the eastern EU Member States that figured in the list and there were none from the northern Member States. WC-IIASA, however, projects the population to be more than 25 percent smaller at 576 million. The 2019 population estimate for Tumut Region is stated above. Equally, it is conceivable that older persons (aged 65 and over) might be tempted to move away from capital and other large cities for their retirement, in order to avoid some of the perceived disadvantages often associated with living in big cities, such as congestion, crime and a higher cost of living. Fast Track (FT): This scenario is the most optimistic one and here it is assumed that countries follow the most rapid education expansion achieved in recent history which is that of South Korea. Statistics for cities refer to the total number of inhabitants according to their usual residence, in other words, the place where a person normally lives, regardless of temporary absences; this is generally their place of legal or registered residence. This age range provides some compatibility taking account of different practices concerning the proportion of young persons remaining within education systems as well (statutory) retirement or pension ages across the EU.
Detailed information concerning the definition of concepts used for assessing the degree of urbanisation is provided in Chapter 2 of a methodological manual on territorial typologies.

While the UN projections are most widely know there are other very carefully produced projections. For example, it’s estimated that the global population in 1990 was 5.34 billion. The UN expects the population of Africa to increase 3.3-fold – from 1.3 billion in 2019 to 4.28 billion by the end of the century. For Asia, the UN projects an increase only until the mid-21st century when population is projected to plateau around 5.3 billion. Under this scenario the WC-IIASA researchers project a global fertility rate just below 2 and a fertility rate for Africa just above 2. Once health improved and mortality declined things changed quickly. We are looking at all of these drivers separately. “The population growth turns into a blessing when it produces educated and trained labor — which will be an addition to the country’s economy — but this is not the case in Egypt where a large portion of the Egyptian labor are not well prepared to be enrolled in the labor market.” More from Mohamed Sabry.
For more information on the “population dividend” see: [http://www.unfpa.org/demographic-dividend](http://www.unfpa.org/demographic-dividend). While the UN projects a 3.5-fold increase of the population of Africa, other researchers find a much smaller increase more likely. Population projections show that the yearly number of births will remain at around 140 million per year over the coming decades. This will still result in further improvements of adult education because in many countries the younger cohorts are better educated than the older ones. The Europe 2020 target for the employment rate (the ratio of employed persons compared with the population of the same age group) is to ensure that 75 % of people aged 20-64 years are employed by 2020. Global population projections are also published by the US Census, the Population Reference Bureau (PRB), and by the closely related Austrian research centers IIASA and the Wittgenstein Centre. The table below shows the population in 2016. This also means that the extended family with many children, that we often associate with the past, was only a reality for glimpse in time. In the last census in 2016, Tumut Region had a population of 4,715 persons. By contrast, the four largest EU Member States in population terms — Germany, France, Italy and the United Kingdom — all recorded their lowest unemployment rates among people living in rural areas and their highest rates among people living in cities, thereby collectively greatly influencing the overall EU-28 figures. In the same year, the death rate was 5.4 per 1000 people (~ 439,000 deaths) and the birth rate was 16.0 per 1000 people (~ 1,300,000 births). This is described in Samir KC and Wolfgang Lutz (2017) – The human core of the shared socioeconomic pathways: Population scenarios by age, sex and level of education for all countries to 2100. The WC-IIASA projections are a set of influential projections, published by IIASA and the Wittgenstein Centre,10 and are helpful to gauge how much smaller the world population will be if the world develops faster. The age structure of EU cities was somewhat skewed insofar as 556 recorded ratios that were below the EU-28 average, compared with 358 that had higher than average young-age dependency ratios; five cities had the same ratio. We would therefore expect growth to come to an end very soon after 2100.
