Suicide rates in Lithuania have more than halved since their 1990s peak

Forty years ago in Japan, two babies were born for every person who died. Twenty years ago, these numbers were equal. And today, the ratio has reversed: one baby is born for every two people who die.In the chart, you can see this change in the number of births and deaths over time.Since deaths now greatly outnumber births, and because immigration is low, Japan’s population has started to shrink.See which other countries now have more people dying than being born.

Debates over whether religion is booming or dying are common. What does the data say?Most countries lack long-term data on religious identity, but results from the Pew Research Center offer insights into changes over the decade from 2010 to 2020. (Unfortunately, 2020 is the most recent year for which we have comparable global data.)At a global level, there was barely any change. The share of people identifying with any religion dropped by just one percentage point, from 77% to 76%.But religious affiliation did drop significantly across many countries in Europe, the Americas, and Oceania. You can see this drop for a selection of countries in the chart.In Australia, rates dropped from 75% to 58%. In the United States and Chile, the percentage has decreased from roughly 85% to 70%.So while religious affiliation is stable in many parts of the world, this data shows religion is becoming less prominent in others.Note that this data is based on self-identification with any religion; it doesn’t tell us about changes in practices or rituals, such as prayer or attending services.Explore more data on religious identification, importance, and the frequency of practices across the world in our new topic page on religion.

This chart shows one way to compare automated manufacturing across countries — it plots the number of robots per 1,000 manufacturing employees.The chart shows very large differences between countries. South Korea stands out, with more than one robot for every ten manufacturing workers.Singapore comes second, and China ranks third, close to Germany. The United States sits in the middle, close to the European average, below Switzerland, Denmark and Slovenia.This perspective shows industrial robot adoption in relative terms. In another Data Insight, I looked at robot adoption in absolute terms. From that perspective, China stands out by a large margin: it’s a large economy with a huge manufacturing sector, and it has by far the largest stock of industrial robots.Much of this expansion has happened recently: China’s annual installations increased 12-fold over a decade, helping it catch up to South Korea in terms of robots per worker.Explore the interactive version of this chart

Most people in the world are religious. When asked whether they identify with any religion, three-quarters of respondents choose one.But in the chart, you can see huge differences in rates of religious affiliation across the world. In some countries, such as India and Pakistan, it’s almost universal: almost everyone identifies with a religion.The opposite is true in China, where just one in ten people does. Several countries in East Asia, in particular, have particularly low rates of religious identification compared to other regions.This doesn’t necessarily mean these populations hold no religious beliefs; they may still engage in activities that can be considered religious or spiritual, even though they don't describe themselves as belonging to any one in particular.We show here just a small selection of countries; you can explore data for many more in our new topic page on religion.

It might seem odd that countries would agree to import plastic waste from other countries, but many do so for the cheap materials or to feed specific manufacturing processes.Environmentally, the trade in plastics has often been a concern, as it allows rich countries to effectively “dump” waste on poorer countries with weaker waste management systems.The good news is that trade in plastic waste has fallen by more than two-thirds over the last decade. You can see this reduction in the chart.China has been the biggest driver of this. It was once a large importer, but after a steep decline in trade in 2016 and a ban in 2018, many countries lost their largest export market.In 2024, around 5 million tonnes of plastic waste were traded worldwide. For context, that is around 1% of the total plastic waste generated. What’s perhaps surprising is that most trade is now between high-income countries, which reduces the risk that this waste leaks into the environment.Learn more in our updated topic page on plastic pollution.

Three-quarters of people worldwide say they are religious. But rates of religious identity can vary a lot across countries, and so do the particular religions people follow.In the map, you can see the most common religious affiliation for each country. This can include the “unaffiliated” who do not identify with any specific religion. This data is sourced from the Pew Research Center and is based on how people describe their own identity, regardless of their particular practices or beliefs.As you can see, Christianity is the most common across much of Europe, the Americas, and Sub-Saharan Africa. Islam is the most common across North Africa and the Middle East, while Hinduism and Buddhism dominate across much of South Asia.In East Asian countries such as China, Japan, and South Korea, the religiously unaffiliated are the biggest group. That doesn’t mean these populations hold no religious beliefs; they may still engage in activities that can be considered religious or spiritual, but they don’t describe themselves as belonging to any one in particular.Explore the full breakdown of religious affiliations within each country, beyond just the most common answer.
