Africa has the youngest population in the world. Among the 35 countries with the lowest median age worldwide, only three fall outside the continent. In 2023, the median age in Niger was 15.1 years, the youngest country. This means that at this age point, half of the population was younger and half older. A young population reflects several demographic characteristics of a country. For instance, together with a high population growth, life expectancy in Western Africa is low: this reached 57 years for men and 59 for women. Overall, Africa has the lowest life expectancy in the world.

Africa’s population is still growing Africa’s population growth can be linked to a high fertility rate along with a drop in death rates. Despite the fertility rate on the continent, following a constant declining trend, it remains far higher compared to all other regions worldwide. It was forecast to reach 4.12 children per woman, compared to a worldwide average of 2.31 children per woman in 2024. Furthermore, the crude death rate in Africa overall dropped, only increasing slightly during the coronavirus (COVID-19) pandemic. The largest populations on the continent Nigeria, Ethiopia, Egypt, and the Democratic Republic of Congo are the most populous African countries. In 2023, people living in Nigeria amounted to around 224 million, while the number for the three other countries exceeded 100 million each. Of those, the Democratic Republic of Congo sustained the fourth-highest fertility rate in Africa. Nigeria and Ethiopia also had high rates, with 5.24 and 4.16 births per woman, respectively. Although such a high fertility rate is expected to slow down, it will still impact the population structure, growing younger nations.

Globally, about 25 percent of the population is under 15 years of age and 10 percent is over 65 years of age. Africa has the youngest population worldwide. In Sub-Saharan Africa, more than 40 percent of the population is below 15 years, and only three percent are above 65, indicating the low life expectancy in several of the countries. In Europe, on the other hand, a higher share of the population is above 65 years than the population under 15 years. Fertility rates The high share of children and youth in Africa is connected to the high fertility rates on the continent. For instance, South Sudan and Niger have the highest population growth rates globally. However, about 50 percent of the world’s population live in countries with low fertility, where women have less than 2.1 children. Some countries in Europe, like Latvia and Lithuania, have experienced a population decline of one percent, and in the Cook Islands, it is even above two percent. In Europe, the majority of the population was previously working-aged adults with few dependents, but this trend is expected to reverse soon, and it is predicted that by 2050, the older population will outnumber the young in many developed countries. Growing global population As of 2025, there are 8.1 billion people living on the planet, and this is expected to reach more than nine billion before 2040. Moreover, the global population is expected to reach 10 billions around 2060, before slowing and then even falling slightly by 2100. As the population growth rates indicate, a significant share of the population increase will happen in Africa.

Lake Erie walleye (Stizostedion vitreum) recruitment fluctuates annually and depends partially on their diet and growth during their first year of life. To determine how age-0 walleye have responded to changes in prey species and abundance, larval and young of year walleye were collected from western Lake Erie in 2019 and 2014. Larval and young of year fish stomachs were extracted and dissected, with prey contents removed for later identification. All prey contents were identified to the lowest possible taxonomic level using a dissecting microscope and counted, with up to 20 prey items from each taxa per fish measured (0.01 mm) using a digital computer image analysis system. Zooplankton prey items were identified to order, family, or genus and measured for body length, excluding the spine. Invertebrate prey items were identified to order, family, or genus and measured for body length and/or head capsule width. Fish prey items were measured for total length, standard length, backbone length, or otolith length depending on their degree of digestion.

In 2021, there were around 207 million children aged 0-4 years in Africa. In total, the population aged 17 years and younger amounted to approximately 650 million. In contrast, only approximately 48 million individuals were aged 65 years and older as of the same year. The youngest continent in the world Africa is the continent with the youngest population worldwide. As of 2023, around 40 percent of the population was aged 15 years and younger, compared to a global average of 25 percent. Although the median age on the continent has been increasing annually, it remains low at around 20 years. There are several reasons behind the low median age. One factor is the low life expectancy at birth: On average, the male and female population in Africa live between 61 and 65 years, respectively. In addition, poor healthcare on the continent leads to high mortality, also among children and newborns, while the high fertility rate contributes to lowering the median age. Cross-country demographic differences Africa’s demographic characteristics are not uniform across the continent. The age structure of the population differs significantly from one country to another. For instance, Niger and Uganda have the lowest median age in Africa, at 15.1 and 16.1 years, respectively. Not surprisingly, these countries also register a high crude birth rate. On the other hand, North Africa is the region recording the highest life expectancy at birth, with Algeria leading the ranking in 2023.

Young population of West Midlands reduced by 2.17% from 1,099,900 persons in 2020 to 1,076,050 persons in 2021. Since the 0.43% increase in 2019, young population dipped by 2.10% in 2021.

The US Forest Service, Pacific Northwest Research Station, and Oregon State University established the Young Stand Thinning and Diversity Study (YSTDS) in 1990 to demonstrate and test options for young stand management in western Oregon. The YSTDS is designed to determine if different thinning, underplanting, and snag creation treatments in 35-50 year-old plantations can accelerate the development of late-seral conditions. The study was implemented on 4 replicate blocks, each consisting of an untreated Control stand and 1 each of the following stand-level thinning treatments: (1) a Light Thin treatment, approximating the timber industry standard, with about 260 residual trees per hectare (tph; 100/acre); (2) a Heavy Thin treatment leaving approximately 130 tph (50/acre) and underplanted with native conifer seedlings; and (3) a Light Thin with Gaps (hereafter simply “Gaps”) treatment, again with 260 tph plus an additional 20% of the stand area harvested to leave 0.2 ha (0.5-acre) o ...

In 2024, the median age in Africa was 19.2 years, meaning that half of the population was older and half was younger than that age. The median age on the continent increased compared to 2000 when it was around 17 years. Africa is the youngest continent in the world and presents the highest share of inhabitants aged 14 years and younger, that is, 40 percent of the total population. Niger, Uganda, and Angola were the countries with the youngest population in Africa as of 2023.

Parenthood can be defined by the contradiction that it is one of the most satisfying yet stressful experiences in life. Many parents experience stress during parenthood, and some to the extent that they display symptoms of parental burnout. Nevertheless, research on parental burnout is scant and many studies have only examined the condition in Western settings. The aim of this study was to examine parental burnout among Somali mothers in Mogadishu, Somalia, and its association with certain psychological, psychosocial, and sociodemographic factors. In this cross-sectional study, questionnaire data were collected through the measurements Parental Burnout Assessment and Patient Health Questionnaire 9, as well as through social and demographic questions. A total of 882 Somali mothers in Mogadishu participated. The analysis methods used were univariate, bivariate, and multiple linear regression analysis. The results revealed that the mean parental burnout score was low in the sample. Additionally, a significant association was found between higher levels of parental burnout and higher levels of depression, perceived lack of social support, being unmarried, having a low monthly household income, and when the youngest child was of school-age.

According to the survey, 76 percent of the youth respondents from Indian cities felt that it was okay for women to wear western clothes or jeans in colleges during 2019. However, 20 percent of the young people from the country weren't accepting of women wearing western attires in educational institutions in that time period.

The median age of the population in London was 35.9 years in 2023, the lowest median age among regions of the United Kingdom. By contrast, South West England had a median age of 43.9, the highest in the UK.

As of June 2023, in the state of Western Australia in Australia, about 7.7 percent of the population was between 35 and 39 years old. In comparison, just 1.9 percent of the population was over the age of 85.

Niger has the highest child marriage rate in the world among girls. According to the most recent data, in this West African country, more than three fourths of girls aged under 18 were married, with nearly 30 percent of them being younger than 15 years old. The Central African Republic, Chad, and Mali followed behind with rates ranging from 61 to 54 percent. This issue is globally spread, particularly in African countries. In many of these countries, the legal age to get married is lower for females than for males. In Niger and Chad, for instance, the legal age is 15 years for females and 18 for males. In Guinea, instead, the legal age for marriage is 17 for females and 18 for males. Child marriage is often related to poverty, with poor families choosing to marry away their girls both in order to earn money as a wedding gift and as this means fewer mouths to feed.

As of September 2023, 29 percent of Facebook users in the United States were aged 30 to 39 years, while a further 29 percent of users were aged 50 to 64 years, making these demographics the biggest audiences of the online network in the country. Meta’s Instagram was also popular among users aged 30 to 39 years, who accounted for 32 percent of the audience of the photo-based platform, while those aged 18 to 29 years accounted for another third of the network’s U.S. users. Overall, TikTok and Snapchat were the most popular social media platforms amongst younger audiences, while LinkedIn was the least used platform by those aged 18 to 29 in the United States as of 2023.

The social media market in the United States

The number of social media users in the United States has shown continuous growth in the past years, and it is forecast to continue increasing to reach 342 million users in 2029. As of 2023, the social network user penetration in the United States amounted to an impressive 91.56 percent, meaning that more than nine in ten people in the country engaged with online platforms. Furthermore, Facebook was by far the most popular social media platform in the United States, accounting for 45 percent of all social media visits in 2023, followed by Pinterest with 21.2 percent of visits.

The global social media landscape

As of April 2024, 5.07 billion people were social media users, accounting for 62.6 percent of the world’s population. Northern Europe was the region with the highest social media penetration rate with a reach of 80.2 percent, followed by Western Europe with 78.2 percent and Eastern Asia 74.9 percent. In contrast, less than one in ten people in Middle Africa used social networks. Facebook’s popularity is not limited to the United States: this network leads the market on a global scale, and it accumulated more than three billion monthly active users (MAU) as of 2024, which is far more any other social media platform. 272014 YouTube, Instagram, and WhatsApp followed, all with two billion or more MAU.

While more than three-quarters of Canadians are concerned that developments on the Russia-Ukraine border could lead to a major conflict between Russia and Western allies, the degree of concern is somewhat different depending on the age of those surveyed. Indeed, the oldest people are more likely to be worried (79 percent of people over 55) than the youngest (64 percent of 18-24 year olds).

The median age of Germans in 2020 was 44.9 years, meaning that half the German population was younger, half older. This number decreased slightly from 1950 to 1970, likely due to the baby boom after World War II, then began increasing. It is expected to slowly increase to 47.4 by 2100. Aging in Germany This shift in the age makeup of Germany is driven by having fewer young people and more old people. While it has increased slightly in the last decade, the German fertility rate remains low. Fewer young people lead to a higher median age. Simultaneously, the life expectancy has increased, having the opposite effect. Regional and global trends The entire European Union, due to higher levels of development, shows an upward shift in its age distribution. While this shift is occurring globally, the level of Germany’s median age is a European phenomenon. In other parts of the world, the proportion of young and old inhabitants is skewed sharply toward the young, pulling the median age lower.

In 2023, there were estimated to be 956,116 people who were aged 35 in the United Kingdom, the most of any age in this year. The two largest age groups during this year were 30-34, and 35 to 39, at 4.7 million and 4.64 million people respectively. There is also a noticeable spike of 693,679 people who were aged 76, which is due to the high number of births that followed in the aftermath of the Second World War. Over one million born in 1964 In post-war Britain, there have only been two years when the number of live births was over one million, in 1947 and in 1964. The number of births recorded in the years between these two years was consistently high as well, with 1955 having the fewest births in this period at 789,000. This meant that until relatively recently, Baby Boomers were the largest generational cohort in the UK. As of 2022, there were approximately 13.76 million Baby Boomers, compared with 14 million in Generation X, 14.48 million Millennials, and 12.9 million members of Gen Z. The youngest generation in the UK, Generation Alpha numbered approximately 7.5 million in the same year. Median age to hit 44.5 years by 2050 The population of the United Kingdom is aging at a substantial rate, with the median age of the population expected to reach 44.5 years by 2050. By comparison, in 1950 the average age in the United Kingdom stood at 34.9 years. This phenomenon is not unique to the United Kingdom, with median age of people worldwide increasing from 23.6 years in 1950 to a forecasted 41.9 years by 2100. As of 2022, the region with the oldest median age in the UK was South West England, at 43.9 years, compared with 35.9 in London, the region with the youngest median age.

Spain had the oldest mean average age of marriage in Europe for both males and females at 36.8 for males, and 34.7 for females in 2022. By contrast, Poland had the youngest average age at marriage for males, at 30.7 and Romania for females at the age of 28.
