Earth Could Have Billions More People Than We Ever Realized.
For decades global population estimates have been the foundation of policymaking, infrastructure planning and resource allocation. However a new study suggests that we may have vastly underestimated the world’s rural population by as much as 84 percent in some cases. If true, this revelation could mean that Earth's actual population is billions higher than previously thought. A research team led by environmental engineer Josias Láng Ritter from Aalto University has provided the first concrete evidence that a significant portion of the rural population is missing from global datasets. Their study published in New Scientist highlights a striking discrepancy in population data particularly in less developed rural areas where data collection has historically been inconsistent and inaccurate.
The Discovery: Billions of People Missing?
The study analyzed global population data from 1975 to 2010 using a unique approach tracking the displacement of people due to dam construction projects. This scenario offers a rare opportunity for accurate on the ground verification as governments and organizations typically keep detailed records of displaced populations. By comparing official displacement figures with data from five major global population datasets the researchers uncovered a massive underestimation of rural populations. According to their findings rural populations have been undercounted by 53 percent to 84 percent over the studied period. The implications of this are profound. If rural population estimates are significantly off then the global human population might be far higher than the currently accepted figure of approximately 8 billion people.
Why Are Rural Populations Undercounted?
The underestimation of rural populations largely stems from the lack of detailed granular data available in remote regions. While urban populations are well documented due to frequent censuses extensive infrastructure and better digital records rural communities often lack these mechanisms. Some key reasons for the discrepancies include:
Infrequent Census Data: Many countries especially in Africa South Asia and Latin America conduct censuses irregularly or with incomplete coverage in rural areas.
Lack of Health and Infrastructure Data: Population estimates often rely on records from healthcare facilities schools and other services many of which are sparse or absent in rural regions.
Satellite Imagery Limitations: While satellite technology has improved population tracking it still struggles to distinguish between small rural dwellings and natural landscapes, leading to undercounting.
The Real World Impact of Population Undercounting
Accurate population data is crucial for numerous global initiatives, including:
Resource Allocation: Governments and international organizations use population estimates to distribute food, medical supplies, and infrastructure investments. An undercounted population means millions (or even billions) could be missing out on essential resources.
Climate Change Planning: Rising sea levels, extreme weather, and migration patterns are all influenced by population density. If the world has far more people than we thought, climate change risks could be even greater.
Economic and Social Policies: Many economic projections and social welfare programs are based on estimated population sizes. A major undercount could result in flawed policy decisions at both national and global levels.
Skepticism and Debate Among Experts
Not everyone agrees with the study’s conclusions. Some researchers argue that recent advances in satellite imagery, AI-driven population estimation, and improved national data collection have significantly reduced errors in global population estimates. They believe that while undercounting may exist, it is not as severe as the study suggests.
Moreover, some scientists point out that if billions of people were truly missing from the data, we would see far greater mismatches in global food supply, economic output, and infrastructure demand. They caution against drawing extreme conclusions without further verification.
What Happens Next?
Even if the discrepancy is on the lower end of the study’s estimates, correcting the global population count by hundreds of millions—or even billions—would be a monumental shift. Governments, researchers, and international organizations must take this study seriously and invest in more accurate, real-time population tracking methods.
Improving census coverage, leveraging AI to analyze satellite data more precisely, and integrating mobile phone and digital footprint tracking could help close the population data gap. If confirmed, the study’s findings could reshape how the world plans for its future, from food security to climate action and beyond.
One thing is certain: whether we are underestimating the global population by millions or billions, this conversation is just beginning.

The ‘Space Laser’ Wars Have Begun—And America Wants to Be First to Develop the High-Powered Weapons
The ‘Space Laser’ Wars Have Begun—And America Wants to Be First to Develop the High-Powered Weapons The concept of space based laser weapons has long been a staple of science fiction but it is now rapidly becoming a reality. As technological advancements accelerate major global powers particularly the United States are investing heavily in the development of high powered laser systems designed for space warfare. The emergence of these weapons marks the beginning of a new era of military competition one that extends beyond the Earth’s surface and into the vastness of space. The United States recognizing the strategic advantages of space based lasers has committed substantial resources to research and development in this field. The Pentagon and other defense agencies are exploring the potential of laser weapons to enhance national security neutralize threats and establish dominance in space. Unlike traditional kinetic weapons which rely on projectiles or missiles lasers offer near instantaneous response times precision targeting and the ability to disable enemy satellites and other space assets without generating debris. This makes them an attractive option for modern warfare particularly as nations become increasingly reliant on satellite networks for communication navigation surveillance and military operations. One of the key motivations behind the U.S. push for space-based laser technology is the growing threat posed by adversarial nations particularly China and Russia. Both countries have been actively developing their own space weaponry including anti satellite (ASAT) missiles and electronic warfare capabilities. In recent years China has demonstrated its ability to destroy satellites using ground based missiles while Russia has been accused of testing space based weapons capable of targeting American and allied assets. These developments have raised concerns in Washington about the vulnerability of U.S space infrastructure and the need to counter potential threats with advanced defensive and offensive measures.

Honey, I Shrunk the Datacentres: Is Small the New Big?
When most people think of datacentres, they picture sprawling warehouses full of servers, humming fans, and mountains of cabling. These massive facilities power everything from Netflix streams to artificial intelligence, but they also consume enormous amounts of energy and space. Now, a new trend is emerging: micro-datacentres. Tiny, modular, and often portable, these “datacentre in a box” solutions are challenging the old assumption that bigger is always better. Could small really be the new big in the world of computing? What Are Micro-Datacentres? Micro-datacentres are compact computing hubs designed to perform the same essential functions as traditional datacentres but in a fraction of the space. Think of them as miniaturized cloud factories — smaller, energy-efficient, and often placed closer to the users they serve. Key characteristics include: Compact size: Often no larger than a shipping container or even a cabinet. Energy efficiency: Use less power by focusing on localized computing needs. Modularity: Can be scaled horizontally by adding more units rather than expanding a single huge facility. Edge computing readiness: Positioned closer to where data is generated, reducing latency for IoT devices, AI applications, and streaming services. In short, micro-datacentres take the power of traditional computing and shrink it to fit modern, flexible infrastructure demands. Why Companies Are Embracing Smaller Datacentres There are several reasons the tech world is warming up to smaller datacentres: Energy and Cost Savings – Traditional datacentres consume massive amounts of electricity, sometimes as much as a small town. Micro-datacentres use less power and generate less heat, reducing both energy bills and cooling costs. Local Speed and Low Latency – For applications like AI, gaming, and streaming, milliseconds matter. By placing computing resources closer to users, micro-datacentres reduce latency and improve performance. Flexibility and Rapid Deployment – Big datacentres take years to build. Micro-datacentres can be deployed in weeks, allowing companies to respond quickly to spikes in demand or to expand into new regions. Resilience and Redundancy – Smaller, distributed units reduce the risk of a single point of failure. If one micro-datacentre goes down, others can pick up the load. Sustainability Goals – With energy efficiency at their core, micro-datacentres are often paired with renewable energy, making them an attractive option for companies seeking greener operations. From Data Warehouses to Data Cabinets Historically, the datacentre arms race has been about size. Companies like Amazon, Google, and Microsoft built massive facilities housing hundreds of thousands of servers. These centers achieved economies of scale but came with high energy use, long construction timelines, and heavy regulatory scrutiny. Micro-datacentres, on the other hand, flip the script: instead of one mega-facility, you deploy many smaller units closer to users. This is sometimes called edge computing, and it’s particularly useful for AI applications, smart cities, and the Internet of Things (IoT). Imagine self-driving cars, smart traffic lights, or factory robots. These devices generate enormous amounts of data that can’t be efficiently sent to a distant datacentre for processing. A nearby micro-datacentre solves the problem in real-time, enabling faster decisions and smoother operations. Real-World Examples Several companies are already experimenting with smaller datacentres: Google’s Edge Nodes: Google has deployed compact datacentres in regional locations to speed up cloud services. Microsoft Azure Stack Edge: A modular datacentre solution that brings cloud computing capabilities closer to businesses. Amazon Web Services (AWS) Snowcone: A portable computing and storage unit that can operate in remote or temporary locations. Even municipalities and hospitals are exploring micro-datacentres for localized applications like traffic management, healthcare data storage, and emergency services. Challenges of Going Small While micro-datacentres have many advantages, they’re not without challenges: Limited capacity: They can’t match the raw scale of traditional datacentres, so some large-scale AI training tasks still require mega-facilities. Security concerns: Smaller units distributed across many locations require robust cybersecurity protocols. Maintenance and monitoring: Managing multiple small units can be more complex than running a centralized datacentre. Energy trade-offs: If not designed efficiently, multiple micro-datacentres can sometimes use more energy than a single optimized large facility. Despite these challenges, many experts argue that the benefits — speed, flexibility, and reduced environmental impact — outweigh the downsides for many applications. Why “Small” Could Be the Future The rise of micro-datacentres signals a broader shift in how we think about computing infrastructure. Instead of centralized, monolithic powerhouses, the future may look like a network of small, smart, and sustainable units. This trend aligns with several larger tech movements: Edge computing – Computing closer to the user or device. Green technology – Reducing energy consumption and carbon footprints. AI proliferation – Handling massive data loads locally to enable faster processing. For companies, governments, and communities, the message is clear: smaller doesn’t mean weaker — it can mean smarter, faster, and more adaptable. Conclusion: Small but Mighty Micro-datacentres may not replace all mega-facilities, but they are carving out an essential niche in the computing ecosystem. They offer speed, flexibility, and sustainability that large datacentres can’t always provide, particularly for localized applications and edge computing. As technology evolves and energy concerns intensify, these “datacentres in a box” could become a core component of how we process, store, and access data in the 21st century. So the next time someone asks if small is the new big, the answer might just be yes — at least when it comes to datacentres.
