Global population data is in crisis – here’s why that matters

Curated on Posted on by Stefaan Verhulst

Article by Andrew J Tatem and Jessica Espey: “Every day, decisions that affect our lives depend on knowing how many people live where. For example, how many vaccines are needed in a community, where polling stations should be placed for elections or who might be in danger as a hurricane approaches. The answers rely on population data.

But counting people is getting harder.

For centuries, census and household surveys have been the backbone of population knowledge. But we’ve just returned from the UN’s statistical commission meetings in New York, where experts reported that something alarming is happening to population data systems globally.

Census response rates are declining in many countries, resulting in large margins of error. The 2020 US census undercounted America’s Latino population by more than three times the rate of the 2010 census. In Paraguay, the latest census revealed a population one-fifth smaller than previously thought.

South Africa’s 2022 census post-enumeration survey revealed a likely undercount of more than 30%. According to the UN Economic Commission for Africa, undercounts and census delays due to COVID-19, conflict or financial limitations have resulted in an estimated one in three Africans not being counted in the 2020 census round.

When people vanish from data, they vanish from policy. When certain groups are systematically undercounted – often minorities, rural communities or poorer people – they become invisible to policymakers. This translates directly into political underrepresentation and inadequate resource allocation…(More)”.

How social media and online communities influence climate change beliefs

Curated on Posted on by Stefaan Verhulst

Article by James Rice: “Psychological, social, and political forces all shape beliefs about climate change. Climate scientists bear a responsibility — not only as researchers and educators, but as public communicators — to guard against climate misinformation. This responsibility should be foundational, supported by economists, sociologists, and industry leaders.

While fake news manifests in various forms, not all forms of misinformation are created with the intent to deceive. Regardless of intent, climate misinformation threatens policy integrity. Strengthening environmental communication is thus crucial to counteract ideological divides that distort scientific discourse and weaken public trust.

Political polarisation, misinformation, and the erosion of scientific authority pose challenges demanding rigorous scholarship and proactive public engagement. Climate scientists, policymakers, and climate justice advocates must ensure scientific integrity while recognising that climate science operates in a politically charged landscape. Agnosticism and resignation, rather than resisting climate misinformation, are as dangerous as outright denial of climate science. Combating this extends beyond scientific accuracy. It requires strategic communication, engagement with advocacy groups, and the reinforcement of public trust in environmental expertise…(More)”.

Trump Admin Plans to Cut Team Responsible for Critical Atomic Measurement Data

Curated on Posted on by Stefaan Verhulst

Article by Louise Matsakis and Will Knight: “The US National Institute of Standards and Technology (NIST) is discussing plans to eliminate an entire team responsible for publishing and maintaining critical atomic measurement data in the coming weeks, as the Trump administration continues its efforts to reduce the US federal workforce, according to a March 18 email sent to dozens of outside scientists. The data in question underpins advanced scientific research around the world in areas like semiconductor manufacturing and nuclear fusion…(More)”.

Bubble Trouble

Curated on Posted on by Stefaan Verhulst

Article by Bryan McMahon: “…Venture capital (VC) funds, drunk on a decade of “growth at all costs,” have poured about $200 billion into generative AI. Making matters worse, the stock market’s bull run is deeply dependent on the growth of the Big Tech companies fueling the AI bubble. In 2023, 71 percent of the total gains in the S&P 500 were attributable to the “Magnificent Seven”—Apple, Nvidia, Tesla, Alphabet, Meta, Amazon, and Microsoft—all of which are among the biggest spenders on AI. Just four—Microsoft, Alphabet, Amazon, and Meta—combined for $246 billion of capital expenditure in 2024 to support the AI build-out. Goldman Sachs expects Big Tech to spend over $1 trillion on chips and data centers to power AI over the next five years. Yet OpenAI, the current market leader, expects to lose $5 billion this year, and its annual losses to swell to $11 billion by 2026. If the AI bubble bursts, it not only threatens to wipe out VC firms in the Valley but also blow a gaping hole in the public markets and cause an economy-wide meltdown…(More)”.

Integrating Social Media into Biodiversity Databases: The Next Big Step?

Curated on Posted on by Stefaan Verhulst

Article by Muhammad Osama: “Digital technologies and social media have transformed ecology and conservation biology data collection. Traditional biodiversity monitoring often relies on field surveys, which can be time-consuming and biased toward rural habitats.

The Global Biodiversity Information Facility (GBIF) serves as a key repository for biodiversity data, but it faces challenges such as delayed data availability and underrepresentation of urban habitats.

Social media platforms have become valuable tools for rapid data collection, enabling users to share georeferenced observations instantly, reducing time lags associated with traditional methods. The widespread use of smartphones with cameras allows individuals to document wildlife sightings in real-time, enhancing biodiversity monitoring. Integrating social media data with traditional ecological datasets offers significant advancements, particularly in tracking species distributions in urban areas.

In this paper, the authors evaluated the Jersey tiger moth’s habitat usage by comparing occurrence data from social media platforms (Instagram and Flickr) with traditional records from GBIF and iNaturalist. They hypothesized that social media data would reveal significant JTM occurrences in urban environments, which may be underrepresented in traditional datasets…(More)”.

Panels giving scientific advice to Census Bureau disbanded by Trump administration

Curated on Posted on by Stefaan Verhulst

Article by Jeffrey Mervis: “…U.S. Secretary of Commerce Howard Lutnick has disbanded five outside panels that provide scientific and community advice to the U.S. Census Bureau and other federal statistical agencies just as preparations are ramping up for the country’s next decennial census, in 2030.

The dozens of demographers, statisticians, and public members on the five panels received nearly identical letters this week telling them that “the Secretary of Commerce has determined that the purposes for which the [committee] was established have been fulfilled, and the committee has been terminated effective February 28, 2025. Thank you for your service.”

Statistician Robert Santos, who last month resigned as Census Bureau director 3 years into his 5-year term, says he’s “terribly disappointed but not surprised” by the move, noting how a recent directive by President Donald Trump on gender identity has disrupted data collection for a host of federal surveys…(More)”.

Government data is disappearing before our eyes

Curated on Posted on by Stefaan Verhulst

Article by Anna Massoglia: “A battle is being waged in the quiet corners of government websites and data repositories. Essential public records are disappearing and, with them, Americans’ ability to hold those in power accountable.

Take the Department of Government Efficiency, Elon Musk’s federal cost-cutting initiative. Touted as “maximally transparent,” DOGE is supposed to make government spending more efficient. But when journalists and researchers exposed major errors — from double-counting contracts to conflating caps with actual spending — DOGE didn’t fix the mistakes. Instead, it made them harder to detect.

Many Americans hoped DOGE’s work would be a step toward cutting costs and restoring trust in government. But trust must be earned. If our leaders truly want to restore faith in our institutions, they must ensure that facts remain available to everyone, not just when convenient.

Since Jan. 20, public records across the federal government have been erased. Economic indicators that guide investments, scientific datasets that drive medical breakthroughs, federal health guidelines and historical archives that inform policy decisions have all been put on the chopping block. Some missing datasets have been restored but are incomplete or have unexplained changes, rendering them unreliable.

Both Republican and Democratic administrations have played a role in limiting public access to government records. But the scale and speed of the Trump administration’s data manipulation — combined with buyouts, resignations and other restructuring across federal agencies — signal a new phase in the war on public information. This is not just about deleting files, it’s about controlling what the public sees, shaping the narrative and limiting accountability.

The Trump administration is accelerating this trend with revisions to official records. Unelected advisors are overseeing a sweeping reorganization of federal data, granting entities like DOGE unprecedented access to taxpayer records with little oversight. This is not just a bureaucratic reshuffle — it is a fundamental reshaping of the public record.

The consequences of data manipulation extend far beyond politics. When those in power control the flow of information, they can dictate collective truth. Governments that manipulate information are not just rewriting statistics — they are rewriting history.

From authoritarian regimes that have erased dissent to leaders who have fabricated economic numbers to maintain their grip on power, the dangers of suppressing and distorting data are well-documented.

Misleading or inconsistent data can be just as dangerous as opacity. When hard facts are replaced with political spin, conspiracy theories take root and misinformation fills the void.

The fact that data suppression and manipulation has occurred before does not lessen the danger, but underscores the urgency of taking proactive measures to safeguard transparency. A missing statistic today can become a missing historical fact tomorrow. Over time, that can reshape our reality…(More)”.

Can small language models revitalize Indigenous languages?

Curated on Posted on by Stefaan Verhulst

Article by Brooke Tanner and Cameron F. Kerry: “Indigenous languages play a critical role in preserving cultural identity and transmitting unique worldviews, traditions, and knowledge, but at least 40% of the world’s 6,700 languages are currently endangered. The United Nations declared 2022-2032 as the International Decade of Indigenous Languages to draw attention to this threat, in hopes of supporting the revitalization of these languages and preservation of access to linguistic resources.  

Building on the advantages of SLMs, several initiatives have successfully adapted these models specifically for Indigenous languages. Such Indigenous language models (ILMs) represent a subset of SLMs that are designed, trained, and fine-tuned with input from the communities they serve. 

Case studies and applications 

  • Meta released No Language Left Behind (NLLB-200), a 54 billion–parameter open-source machine translation model that supports 200 languages as part of Meta’s universal speech translator project. The model includes support for languages with limited translation resources. While the model’s breadth of languages included is novel, NLLB-200 can struggle to capture the intricacies of local context for low-resource languages and often relies on machine-translated sentence pairs across the internet due to the scarcity of digitized monolingual data. 
  • Lelapa AI’s InkubaLM-0.4B is an SLM with applications for low-resource African languages. Trained on 1.9 billion tokens across languages including isiZulu, Yoruba, Swahili, and isiXhosa, InkubaLM-0.4B (with 400 million parameters) builds on Meta’s LLaMA 2 architecture, providing a smaller model than the original LLaMA 2 pretrained model with 7 billion parameters. 
  • IBM Research Brazil and the University of São Paulo have collaborated on projects aimed at preserving Brazilian Indigenous languages such as Guarani Mbya and Nheengatu. These initiatives emphasize co-creation with Indigenous communities and address concerns about cultural exposure and language ownership. Initial efforts included electronic dictionaries, word prediction, and basic translation tools. Notably, when a prototype writing assistant for Guarani Mbya raised concerns about exposing their language and culture online, project leaders paused further development pending community consensus.  
  • Researchers have fine-tuned pre-trained models for Nheengatu using linguistic educational sources and translations of the Bible, with plans to incorporate community-guided spellcheck tools. Since the translations relying on data from the Bible, primarily translated by colonial priests, often sounded archaic and could reflect cultural abuse and violence, they were classified as potentially “toxic” data that would not be used in any deployed system without explicit Indigenous community agreement…(More)”.

These Words Are Disappearing in the New Trump Administration

Curated on Posted on by Stefaan Verhulst

Article by Karen Yourish et al: “As President Trump seeks to purge the federal government of “woke” initiatives, agencies have flagged hundreds of words to limit or avoid, according to a compilation of government documents.

The above terms appeared in government memos, in official and unofficial agency guidance and in other documents viewed by The New York Times. Some ordered the removal of these words from public-facing websites, or ordered the elimination of other materials (including school curricula) in which they might be included.

In other cases, federal agency managers advised caution in the terms’ usage without instituting an outright ban. Additionally, the presence of some terms was used to automatically flag for review some grant proposals and contracts that could conflict with Mr. Trump’s executive orders.

The list is most likely incomplete. More agency memos may exist than those seen by New York Times reporters, and some directives are vague or suggest what language might be impermissible without flatly stating it.

All presidential administrations change the language used in official communications to reflect their own policies. It is within their prerogative, as are amendments to or the removal of web pages, which The Times has found has already happened thousands of times in this administration…(More)”

How to Win a War Against Reality

Curated on Posted on by Stefaan Verhulst

Review by Abby Smith Rumsey: “How does a democracy work if its citizens do not have a shared sense of reality? Not very well. A country whose people cannot agree on where they stand now will not agree on where they are going. This is where Americans find themselves in 2025, and they did not arrive at this juncture yesterday. The deep divisions that exist have grown over the decades, dating at least to the end of the Cold War in 1991, and are now metastasizing at an alarming rate. These divisions have many causes, from climate change to COVID-19, unchecked migration to growing wealth inequality, and other factors. People who live with chronic division and uncertainty are vulnerable. It may not take much to get them to sign on to a politics of certainty…

Take the United States. By this fractured logic, Make America Great Again (MAGA) means that America once was great, is no longer, but can be restored to its prelapsarian state, when whites sat firmly at the top of the ethnic hierarchy that constitutes the United States. Jason Stanley, a professor of philosophy and self-identified liberal, is deeply troubled that many liberal democracies across the globe are morphing into illiberal democracies before our very eyes. In “Erasing History: How Fascists Rewrite the Past to Control the Future,” he argues that all authoritarian regimes know the value of a unified, if largely mythologized, view of past, present, and future. He wrote his book to warn us that we in the United States are on the cusp of becoming an authoritarian nation or, in Stanley’s account, fascist. By explaining “the mechanisms by which democracy is attacked, the ways myths and lies are used to justify actions such as wars, and scapegoating of groups, we can defend against these attacks, and even reverse the tide.”…

The fabrication of the past is also the subject of Steve Benen’s book “Ministry of Truth. Democracy, Reality, and the Republicans’ War on the Recent Past.” Benen, a producer on the Rachel Maddow Show, keeps his eye tightly focused on the past decade, still fresh in the minds of readers. His account tracks closely how the Republican Party conducted “a war on the recent past.” He attempts an anatomy of a very unsettling phenomenon: the success of a gaslighting campaign Trump and his supporters perpetrated against the American public and even against fellow Republicans who are not MAGA enough for Trump…(More)”
