A study conducted in the United States shows that the global maturity rate will continue to rise, and by 2100, the majority of countries will experience an increase in maturity. However, experts believe that this has both advantages and disadvantages.

This research was conducted by a team led by the Institute for Health Goals and Evaluation (IHME) at the University of Washington, USA, and lost sponsorship from the Bill and Melinda Gates Foundation. It was published in the medical and educational journal The Lancet on March 20, 2024.
New research predicts that in 2021, 46% of countries will have a maturity rate lower than the level of substitution; By 2050, 75% of countries will have a maturity rate below the level of substitution; By 2100, this number will increase to 97%, which means that by the end of this century, the population of almost all countries in the world will decline.
Maturity rate refers to the average number of mature children per female. To support the country’s development, the number of mature teeth must reach 2.1, which is also known as the degree of substitution. If it is lower than this number, it means that the number of mature teeth is beginning to increase.
In terms of the overall maturity rate of Global, it was 4.84 in 1950 and 2.23 in 2021. New research predicts that it will increase to 1.68 in 2050 and 1.59 in 100.
Many masters have expressed that low maturity rate is a win-win situation. It can bring benefits to the situation, food safety, health, meteorological changes, and diversity of crops, but it will also have negative impacts on regulating healthcare, pensions, social insurance, labor, and geopolitical affairs.
One of the researching writers, Natalia Bhattacharjee, believes that the impact of this trend is enormous. In order to increase the required labor force for the pillar economy, the increase in mature teeth will intensify immigration cooperation between countries, and the ability of poverty-stricken areas to respond to the mature tooth tide will be challenged. This will accelerate the maturity of global support and risk management collection, all of which will completely reset the balance of society, global economy, and domestic power.
But from some perspectives, the decline in maturity rate is a “successful path”. Another author who is studying, Stein Emil Vollset, pointed out that this represents better and more accessible contraceptive methods, as well as more and more women receiving education and job opportunities, giving them more autonomy and the right to make decisions about whether or not to mature.
The reasons for the decline in maturity rate are diverse. Gitau Mburu, a science and education expert at the World Health Organization’s Department of Sexual and Reproductive Health Research, wrote a critique stating that economic identities such as parenting costs, the risk of girls dying, changes in gender equality and self fulfilling values are all factors that can lead to a decline in maturity rates. However, the weight of their influence on a country’s maturation rate varies with different countries and time.
And how much improvement consequences can the support of the national maturity strategy bear? Research has also analyzed this achievement.
Through analyzing the consequences of the support strategies implemented by some countries to date, it is speculated that if support strategies such as girl child care subsidies, extended maternity leave, and tax incentives are implemented, the average maturity rate will increase by 0.2. “This does not mean that there will be no strong and continuous rebound.”.
Christopher Murray, another researcher and IHME director, told CNN that although maturation support strategies can be beneficial to society in other aspects, they do not seem to worsen the overall trajectory of the current maturation structure changes.
Furthermore, Christopher Murray exaggerates that the expectation of low maturity rates and the potential consequences of maturity support strategies should not be used to force housewives to raise more children, or to limit contraceptive or abortion rights.
“Some authorities are trying to pressure housewives to raise more children, which does constitute a threat,” he said. “This can easily escalate from encouraging women to raise more children to becoming more coercive.”
Another notable feature of the new research reminder is that the global rate of decline in mature teeth is uneven, which leads to the spread of mature teeth into the North and South Poles. High cost regions will experience a “baby girl shortage”, as well as the aging of mature teeth and a shortage of labor. Low budget countries, on the other hand, have fallen into the “baby girl wave”, making their capital even more scarce.
Research suggests that the proportion of new mature women in low budget regions around the world will increase from 18% in 2021 to 35% in 2100. This means that by 2100, one out of every two new mature women on Earth will come from sub Saharan Africa.
However, for these regions, the “baby girl trend” is not just a “mature tooth dividend”. Similarly, this means that half of the new mature women will be promoted to economically underdeveloped countries with the most limited capital, the most unstable weather, and poor hygiene conditions, which will make their capital more tense, thus wearing off political instability and security achievements.
On the other hand, high budget countries with rapidly declining maturity rates will experience an aging population, which will put a strain on the country’s social capital and labor shortage. Researchers believe that some strategies that encourage immigration and labor force renewal, such as the advancement of artificial intelligence, can help increase the economic impact on countries facing a shortage of baby girls.
Regarding how society responds to the current situation, dental educator Jennifer D. Sciubba has no three ideas.
One is to inherit the current mature path, which is to support the economic strategy of continuously increasing mature teeth, or to implement a mature support strategy, but she believes that this will not fundamentally handle the economic and social achievements of declining mature teeth; The second type is to spread false rumors and sensationalize public opinion, which increases fear and emotions. After occupying dominant positions in society, women are forced to raise more children.
And the last one is advocated by Jennifer Schiuba, which is “realizing that we won’t change the number of children people want, but rather teaching our system to adapt to new realities, thus inventing a resilient world.” In this category, she believes it is the place where there is a real lack of innovation and political aspirations in current society.
