#Our World in Data

Our recent publications Mortality in the past: every second child died The death of a child is one of the most heartbreaking tragedies. Child deaths were more common in the past. But how common? The evidence shows that, across very different societies and thousands of years, the child mortality rate hovered around 50%. Every second child died. Over the last decades, though, we’ve achieved dramatic progress: the global death rate of children has declined to around 4%. And while this progress has been uneven across countries, every single country in the world has improved. Several countries with the lowest mortality rates show that it is possible for 99.7% of children to survive — this is what the world can aspire to. Global health has improved, and it is on us to make sure that this progress continues, to bring the daily tragedy of child deaths to an end. In this article, read more about the historical estimates of child mortality and the progress we’ve made. We published a major overhaul of our work on the Internet Many of us cannot imagine our lives without the internet. But the technology is still young; only 60% of the world’s population was online in 2020. The internet provides an almost endless list of services: it allows us to communicate and collaborate worldwide; send money internationally; learn and educate others; form cross-border social connections; share news; and much more. On our page, you can find all our data, visualizations, and writing related to the internet. Explore our featured work In most countries, democracy is a recent achievement. Dictatorship is far from a distant memory. For some young people living in democracies, authoritarianism may seem like a long-forgotten part of their country’s history. For as long as they can remember, their fellow citizens have enjoyed the rights associated with democracy, such as the right to vote in meaningful elections and to organize freely.  But these experiences are not representative. About half of all countries are not democracies, and almost all countries that are democratic are younger than a lifetime. This means that for most people, life under authoritarianism is either their current experience, a recent memory, or the experience of their parents or grandparents. In this article, we show and discuss the age of democracies across the world. Artificial intelligence has advanced despite having few resources dedicated to its development – now investments have increased substantially We published a redesign of our work on suicides We published a redesign of our work on the ozone layer The mission of Our World in Data is to make data and research on the world’s largest problems understandable and accessible.

New research reveals that rather than being interconnected by synapses, a comb jelly’s neurons are directly fused together. Scientists have long suspected that the comb jellies evolved their nervous system independently: Emily Singer reported for Quanta on preliminary evidence for it in 2015. New Methods for Spotting Exoplanets By combining two different exoplanet-search techniques, astronomers have discovered a new planet around another star — a giant world designated HIP 99770 b, reports Nola Taylor Tillman for Scientific American. As astronomers invent new ways to hunt for exoplanets, planets that have wider ranges of masses and of orbital distances from their suns become ripe for discovery. In 2020, Nola Taylor Tillman wrote for Quanta about a novel technique for detecting the auroras around giant planets.

These 7 hormones influence how much—or little—you eat. Can we influence them?New medications, like Wegovy and Ozempic, can boost the effects of these hormones. But how we eat, exercise, and manage stress also play a big role in whether we gain or lose weight. How much barbecue beef do you want to eat? It depends on what your hormones are telling your brain. PHOTOGRAPH BY BRIAN FINKE, NAT GEO IMAGE COLLECTION. BYSTACEY COLINO

These microbes found in tumors promote cancer. What if we just kill them?

​New studies show that bacteria help cancer cells evade the body’s immune response. Experts say this relationship could prove vital for wiping out cancer.

Years ago, some scientists scoffed at the notion of bacteria and microbes in cancer cells. Not only are they in there, new studies show they can help cancer cells spread more rapidly (above, an illustration of the human microbiome). The results are pointing to another way to battle these tumors—and encouraging new tools in the fight. Read the full story here.
