South Korea has had the most catastrophic birth rate in the world for years. And now it has finally managed to grow

March 1, 2026 by usatoday24

For a few years now, talking about demographics in South Korea has made it necessary to first take out a clinex package. Despite all his attempts (and there have been not a few) the country seemed condemned to suffer an uncontrollable ‘bleed’ of birth rates and see the seams of its economy tighten. It may sound exaggerated, but it is good to remember that he said goodbye to 2024 by declaring “super aged” and that there are academics who warn that the nation is emptying (literally). With that backdrop, Seoul has started 2026 with a positive fact: wins babies. And it also does so for the second consecutive year. The big question that arises now is… Are we facing a change in trend or just a mirage? The figure: 254,457. It is provisional data (the definitio will not arrive until the summer), but even so it has arrived like manna in a country accustomed to every piece of news about demographics involving a national drama. Last year South Korea registered 254,457 birthsa good balance no matter where you look at it. To begin with because it means 6.8% more that in 2024 and leaves the largest percentage increase since 2007; but those are only two of the possible readings. More babies per woman. Another interesting reading is the one that tells us about the “fertility rate”, the average number of babies that (at a statistical level) a woman is expected to have throughout her reproductive life. A few years ago that indicator plummeted to 0.72very far from the “replacement rate” (2.1 children per woman) that allows societies to remain stable. The data is still below that red line, but at least it has grown: in 2025 it passed from 0.75 to 0.8. Not only that. Reuters remember that the South Korean Government had optimistic estimates that suggested that this rate would grow to 0.75 in 2025 and 0.8 in 2026, which appears to be recovering positions faster than expected. In Seoul the trend is even more pronounced. There the indicator rose 8.9%, going from 0.53 to 0.63. The data is still very poor and they are far away to solve the problem that Korea has, but they suggest a change of cycle. Breaking the bad streak. That the birth rate is increasing in South Korea is news, but it is even more so if (as is the case) that growth is maintained for two years. In 2024 the country has already registered a positive fact (breaking up with eight exercises of consecutive falls) that now invites us to think about whether it has really found the right way to encourage its young people to have more offspring. Of course, the country has invested time, efforts and especially economic resources in that objective, in which it is played from the social sustainability and the march of his industry to issues as relevant as national defense. More weddings, more babies. 2025 has not only been a good year in maternity hospitals. It has also been for the wedding planners. Marriages increased by 8.1% in 2025, reinforcing the 14.8% rebound already recorded in 2024. This is good news because, in a conservative society like South Korea (the percentage of births outside of marriage It’s surprisingly low.), weddings are often considered an early indicator of a rebound in birth rates. Trend or mirage? That’s the million dollar question. That South Korea has been trying to activate its birth rate for years is undeniable, as is the fact that it has invested large resources in this effort and that they have been involved in the effort since the public institutions to the business world. However, there are other factors at play that suggest that the recent growth in the South Korean birth rate could be more circumstantial than structural. That is to say, in reality we would be facing a kind of demographic ‘mirage’. The hangover of the pandemic. When explaining the phenomenon, there are those who point to the influence of the pandemic. Not so much in the birth rate itself as in marriages. It is true that more South Koreans are getting tired and that this indicator will probably influence the birth rate in the coming years, but it is also true that many couples had to postpone their plans during the pandemic. “The number of marriages has increased for 21 consecutive months, from April 2024 to December last year, as couples who had delayed their marriages due to COVID-19 have tied the knot,” recognize Park Hyun-jung, director of the government office that analyzes population trends. He himself admits that today it is very difficult to establish a clear “correlation” between government policies and improved birth rates. A demographic with ‘echo’. There are those who point out, however, another factor that would be directly influencing South Korean demographics: history. The explanation I broke it down Rapahel Rashid recently in Guardian and provides an alternative theory. More babies have been born in the South Korea of 2024 or 2025 simply because the same thing already happened in the Korea of 30 years ago. To be more precise, more or less during the first half of the 1990s (1991-1995) there was a peak of around 3.6 million of babies who today enter their thirties and begin to become parents themselves. Reviewing history. We explain ourselves. Paradoxical as it may be, in the 1950s and 1960s Korea had a very different problem than today: a very high fertility rate which led authorities to launch family planning programs. The objective: guarantee the country’s recovery after the war. The message that was launched was very simple: have fewer children (two, one) and guarantee them a better life. It worked so well that by the early 1980s the fertility rate had fallen below the replacement margin and Seoul decided change course. By doing so, it favored the rebound that would now be heating up the birth rate. According to that theory, what we see today is actually a … Read more

That Mount Fuji erupts would be catastrophic, so the Government of Japan has used AI to warn the population

August 31, 2025 by usatoday24

The Japanese government has published a video created with artificial intelligence that shows the devastating consequences that would have an eruption of the Mount Fuji For the 20 million inhabitants of Tokyo. The video, disseminated last Sunday by the Disaster Prevention Division of the Tokyo Metropolitan Government, is part of a strategy to prepare the population before a natural catastrophe that, although it is not imminent, is possible. What does the video show. The simulation starts with a woman in a crowded street that receives an alert on her mobile informing her that the volcano has erupted. “The moment can come without prior notice,” warns the narrative before showing huge columns of smoke leaving the Fuji. The images generated by AI show how volcanic ash would arrive in Tokyo in just two hours, covering buildings and vehicles, and plunging the capital in the dark even during the day. Why now. Japan is in the Fire belt Del Pacífico, an area of intense seismic and volcanic activity. The country houses 111 of the approximately 1,500 active volcanoes in the world. Mount Fuji, who for centuries erupted every 30 years approximately, He has been asleep since the known as Hoei eruption of 1707. The authorities have intensified the alert tone in the last year, especially after warning in January that there is 80% probability that A severe earthquake hits The Nankai pit region in the next 30 years. The economic and social impact. According to Official estimatesa large -scale rash would produce 1.7 billion cubic meters of volcanic ash, of which about 490 million would accumulate on roads, buildings and other surfaces. Economic losses could reach 2.5 billion yen (about 14,200 million euros). The ash would cause the collapse of wooden buildings with little load capacity, paralyze rail transport, cut the electricity supply and hinder the distribution of essential foods and products. Reactions found. We have had the reactions of all kinds. While some users in networks They have expressed His concern: “The idea that volcanic ash causes chaos in the transport of Tokyo’s metropolitan area is terrifying,” others have criticized the approach for which the government has opted, considering it as alarmist. “It tends to be used to stir a feeling of crisis and fear”, commented Another user. Practical preparation. The Government recommends to residents of areas near the Fuji maintain essential supplies for two weeks. The simulation includes a family scenes preparing pantries with canned food and first aid kit. However, some citizens indicate the practical difficulties of these measures, especially during Japanese summers, when temperatures reach Suffocating levels and an electric cut would be especially problematic.

After two catastrophic failures, we believed that Spacex would not risk with the next starship. We were wrong

April 4, 2025 by usatoday24

Starship’s next flight will be one of the most tense in the history of the rocket. Not only because the last two releases will end in paths explosions and with deviated airplanes to avoid the rain of rubble. Also because it will be the first time that Spacex reuse a rocket. Zero-Touch reflight. In addition to a 123 meters high mole, Starship is the first rocket designed to be quickly reusable. Spacex’s idea is that Starship takes off, lands and throws himself again after a few hours, as if it were a commercial plane. The company has partially advanced in this Objective of “Zero-Touch Desflight” or relaunch without intervention. The first stage of the rocket, the 33 -engines Super Heavy propeller, has landed in the arms of the launch tower three times: Booster 12 in flight test 5, Booster 14 in flight test 7 and Booster 15 in flight test 8. It was planned that the second stage of the rocket, the six -engines Starship ship, would make its first landing attempt during flight 9. To do this, the earth would orbit and re -enter the atmosphere until they perch on the arms of the second launch tower; Already finished in Starbase, Texas. However, the last two starship exploded at 8 minutes of takeoff For a defect in a redesign recent. A second -hand super heavy. The expected thing was that Spacex was taken calmly to flight 9 to compensate for the last failures, but the company has just announced a surprising decision. The next launch, scheduled for mid -April (if the Federal Aviation Administration of the United States is approved), will be done reusing the booster 14 of flight 7. This propeller first took off on January 16, 2025 and, after separating from the Starship ship, returned to the launch base to become the second Super Heavy that Spacex has captured with the arms of the Mechazilla tower. Of the 33 Raptor engines that you will wear during your second launch, 29 are already used engines. Another rocket that lands and takes off. The only orbital rocket with demonstrated capacity for propulsive landing is the Falcon 9 of Spacex. Specifically, its first stage, which usually lands in an autonomous barge in the ocean after throwing satellites or spacecraft. A few weeks later, you are ready to reuse (Generally, in Starlink missions). The second rocket to get it could be Starship, also from Spacex. Not in the “Zero-Touch reflight” mode, but after a restoration process and changing some engines, but it is a first step. And in fact, it is a step that nobody else has achieved apart from Spacex. The company that is closest is Blue Origin, who tried unsuccessfully on the opening flight of the New Glenn rocket. In China, Landspace is also achieved with his Zhuque 3 rocket. There will be no second capture. The bad news is that Spacex will not try to capture the Booster 14. The rocket, which has just passed some ignition tests on land, will merit in a controlled way in the Gulf of Mexico to test a more pronounced attack angle during the re -entry, which in the future will allow you to perform other flight profiles. Anyway, all eyes will be put in the Starship 35the third ship of the “Block 2” version. Its two predecessors exploded shortly after separating from the Super Heavy propeller, both for a flight of propellents due to excessive vibrations in the engines area. Starship 33 disintegrated after a fire and Starship 34 lost control after the explosion of an engine. The investigation of flight 8 is still open, so FAA has not yet given its authorization for flight 9. Even so, we should not take long to see it, taking into account that the rocket is almost ready and the renewed political power of Elon Musk It has already allowed accelerating the procedures in the previous releases.
