According to the latest trade statistics from the World Bank’s World Development Indicators, the sum of exports and imports across countries amounted to 63% of global GDP in 2022, the most recent year available.

This metric, also known as the trade openness index, represents the ratio of total trade (exports plus imports) to global output. The higher this ratio, the greater the influence of international trade transactions on global economic activity.

The chart shows the trade openness trend since 1970. After a decade of ups and downs, with a noticeable dip in 2020, trade rebounded above pre-pandemic levels in 2022.

In fact, from a long-run perspective, the 63% observed in 2022 was historically unprecedented.

Economic historians estimate that in 1912, at the peak of the “first wave of globalization”, the trade openness index reached 30%. Global trade declined substantially during the First and Second World Wars, then increased again with the onset of the “second wave of globalization”, exceeding 50% of GDP at the beginning of the 21st century.

The fact that global trade openness was higher in 2022 than ever before may seem surprising, given that several countries that followed different trajectories received considerable attention in the media. For example, imports and exports peaked at 65% of GDP in China in 2006 but have since declined to 38% in 2022.

This chart shows death rates across the first year of a baby’s life and how they have been reduced over time.

The data spans 1921 to 2021 and comes from the Office for National Statistics in England & Wales.

On the left-hand side of the chart, you can see that death rates are much higher on the first day of life. They then drop sharply over the following days and continue declining gradually over the rest of the year.

But you can also see that over decades, the entire curve has shifted downwards. This means that every day of infancy is safer than in the past.

The chart shows the global number of children and adolescents who are not in school across primary and secondary education.

According to the most recent UNESCO data, this number has fallen from 390 million in 2000 to 244 million in 2023. That’s nearly a 40% reduction. The global population of children has grown during this time, making the decrease in out-of-school children even more significant.

Many more children are getting an opportunity to learn now than 20 years ago, but progress has stagnated in the last five years.

Historically, more girls than boys were out of school, but this gap has nearly closed. Unfortunately, the global aggregate data split by gender has not been updated by UNESCO since 2019. This makes it hard to track recent progress between boys and girls.

In 1820, only 1 in 10 people over the age of 15 could read. Today, the corresponding global literacy rate — the share of adults aged 15 and older who can read and write — is 87%. That means more than 5 billion people can read and write today, compared to fewer than 100 million two centuries ago.

The chart shows the rising global literacy rate over time. The data combines historical estimates from academic historians with more recent statistics from UNESCO.

As we can see, widespread literacy is a recent achievement. This trend underlines a huge achievement, but it’s important to remember that there’s still much progress ahead of us. In many schools, children learn very little, and many still do not attend school.

Romania tops the list of countries with the highest alcohol consumption per person, with Georgia, Czechia, Latvia, and Germany rounding out the top five. This is according to the global estimates made available by the World Health Organization (WHO), the latest data referring to 2019.

Alcohol consumption is measured here in liters of pure alcohol to account for beer, wine, and spirits having different alcohol content, ranging from around 5% by volume for a typical beer to 12% for wine to 40% or more for spirits.

To make this more concrete, the average Romanian drinks an estimated 17 liters of pure alcohol per year — roughly equivalent to a weekly consumption of 18 bottles of beer (355 mL each) or 3.6 bottles of wine (750 mL each).

In contrast, alcohol consumption is very low in some countries, particularly in the Middle East and North Africa.

Cases of guinea worm disease have fallen dramatically in recent decades. According to the WHO, over 890,000 cases were recorded worldwide in 1989. As you can see on the chart — which we just updated with the latest data — only 14 human cases were reported in 2023.

Guinea worm disease is caused by the parasitic guinea worm, which mainly spreads through stagnant water sources like ponds. The worm’s larvae enter the human body when a person drinks contaminated water, after which they penetrate the digestive tract to mature and reproduce within the body.

Around a year after the initial infection, the adult female breaks through the skin's surface, creating a painful blister through which it gradually emerges over several weeks. When it comes into contact with water, it releases new larvae and continues its life cycle.

The disease was previously endemic in over 20 countries in South Asia and Africa. An international eradication campaign has substantially decreased the number of cases by improving access to clean drinking water and actively monitoring and containing cases in endemic regions.

Since 2020, 14 countries have consistently generated over 95% renewable electricity, according to Ember’s Yearly electricity data. In eight of these countries, electricity has been almost entirely renewable-based for over 20 years.

Renewable sources include hydropower, solar, wind, geothermal, biomass, tidal, and wave power. In all these countries, the largest source of electricity was hydropower.

Sub-Saharan countries, however, use significantly less electricity in their energy mix compared to countries in Europe or North America.

Some regions are warming faster than others, and countries in the Eastern Mediterranean region have seen some of the most rapid warming.

We observe this through temperature anomalies. Anomalies compare current temperatures to historical averages, showing us shifts over time. In the chart, each bar represents the temperature anomaly for a given year.

In 2023, the global average temperature anomaly was 0.6°C above the 1991–2020 average. However, these anomalies vary by region. In countries such as Syria and Turkey, the average annual surface air temperature in 2023 was around 1.2°C above the 1991–2020 average, compared to approximately 0.3°C in Australia.

This pattern is not a one-off difference; it is also reflected in the decadal temperatures. This data comes from the European Centre for Medium-Range Weather Forecasts (ECMWF) ERA5 project.

We update this data every month: you can track monthly temperature changes across the globe and at the national level on our site.

This rise and fall of smoking is shown in this chart. Smoking rates grew rapidly across rich countries in the 20th century. But by the 1980s, they went into steep decline.

It looked like poorer countries would follow a similar path as incomes increased, but rates have decreased there, too. The global share of people who smoke has kept falling in the 21st century, from 34% in 2000 to 23% in 2020.

This is great news for global health. Smoking still kills millions every year, but death rates are falling as people turn their backs on cigarettes.

Around 1.2 million people die from road injuries every year. That includes the deaths of drivers, passengers, and pedestrians.

That’s around 2.3% of deaths from all causes.

As the chart shows, this death toll has barely changed for decades. However, with a larger global population and many more cars on the road, this means the death rate from road injuries — the number of deaths per 100,000 people — has fallen.

According to data from the Global Terrorism Database, the share of deaths from suicide terrorism increased significantly after the attacks of September 11, 2001.

Deaths from these types of attacks continued to be common in the following years, frequently making up about a quarter of all deaths due to terrorism.

However, from 2016 to 2020, the share of deaths from suicide attacks dropped. In 2021, which is the most recent data available, they made up only about 5% of terrorism deaths.

The same upward and downward trends can be seen in both the total number of deaths from suicide attacks and the share of all terrorist attacks that are suicide attacks.

The world has made much progress in reducing global hunger over the last 50 years. Despite fast population growth, the amount of food produced per person has continued to increase.

Rates of hunger — defined as not having enough calories to sustain a healthy and productive life — were estimated to be as high as 1 in 3 people in developing countries in 1970. Since then, rates have fallen substantially.

However, as you can see on the chart, this progress has stalled over the last few years. In some regions, it has even reversed. In 2017, 7.6% of the world did not get enough calories. By 2022, this had risen to 9.2%.

Conflict, extreme weather, and the impacts of the COVID-19 pandemic have all contributed to this reversal.

In recent years, tens of thousands of people have died due to fighting between drug cartels in Mexico.

The chart uses data from the Uppsala Conflict Data Program to show the country's deaths from “non-state conflicts” over the last thirty years.

These conflicts involve fighting between non-state armed groups, which in Mexico are criminal organizations like the Jalisco, Juarez, Los Zetas, and Sinaloa drug cartels.

Before the 2000s, there were relatively few deaths from these conflicts. The number of deaths then began to increase, reaching a peak of over 18,000 deaths in 2021.

The world started adding lead to gasoline in the 1920s. It improved vehicle efficiency and engine performance. However, lead has proven to be a toxic pollutant, particularly for children. Using it in gasoline pollutes the air in cities worldwide, significantly impacting human health.

It took a long time for countries to start taking action. In 1986, Japan became the first country to ban leaded gasoline in cars completely. You can see this on the first map of the timelapse: at the time, leaded gasoline was still in use everywhere else. Since then, bans have been rolled out across the world.

Three and a half decades later, in 2021, Algeria became the last country to ban it. Leaded gasoline is now banned from being used in road vehicles in every country. It is a big win for the health of people around the world.

Homicide rates in Europe surged in the second half of the twentieth century but have dropped over the last 30 years.

The chart shows the rates for several European countries based on data from the WHO Mortality Database.

You can see that this trend was most pronounced in Italy. Homicide rates more than doubled from less than 1 per 100,000 people in the late 1960s to more than 2 in the late 1980s and early 1990s. Since then, rates have even fallen below earlier levels.

This rise and fall in homicides is relatively consistent across other European countries, although the timing and magnitude of these changes differ. France, for example, saw a wave of homicides in the late 1950s and early 1960s.

Data on mental health is neglected or unavailable in many countries, especially in Africa and Asia.

The map shows which countries have reported recent data on mental health in the population and how they have reported them. This is based on surveys conducted for the World Health Organization’s Mental Health Atlas (2023).

Several countries have not compiled mental health data in recent years, as shown in red.

Other countries have compiled recent data, but only for general statistical purposes — without using it in specific reports to inform policy, planning, or management purposes. These countries are shown in light green.

Without regular data, it’s difficult to track whether progress is being made or if new problems are emerging and guide resources to address mental health issues.

This means many people’s difficulties with mental health can go unnoticed and unaddressed.

The Internet is one of the world’s fastest-growing technologies.

In 2010, just 30% of the global population was online. Within a decade, this figure had doubled to 60% in 2020. And it’s still growing rapidly, as the chart shows.

There are, however, large inequalities. In North America and Europe, more than 80% are online, compared to just 30% in Sub-Saharan Africa.

The quality of this access is also very different: this indicator is based on someone having used the Internet at least once in the last three months. The experience of someone having non-stop connections on their smartphone will be very different from someone logging on in a public space once a month.

But the dominant trend globally — and across all regions — is that more people are coming online every year. It’s a technology that’s moving incredibly fast.

Free time is important to most people around the world.

As shown on this chart, in many countries, leisure is important to more than 80% of people. This is based on data from the European Values Study and World Values Survey.

However, the percentage of people who find leisure “very important” varies more. In some countries, it is the majority; in others, it is less than a quarter.

People enjoy their free time, but valuing leisure a lot doesn’t mean people value work less or work fewer hours. In countries such as Nigeria, Mexico, and Indonesia, people put a high value on both these aspects of their lives.

The death rate from malaria has gradually decreased since 2004, but disruption to healthcare programs caused by the COVID-19 pandemic caused a sudden increase in death rates in 2020 and 2021.

According to the latest Global Burden of Disease Study — published earlier this year by the Institute of Health Metrics and Evaluation (IHME) — the age-standardized death rate from malaria was 14.8 deaths per 100,000 in 2004 and had fallen by almost 40% in 2019, to 9.3 deaths per 100,000.

However, in 2020, it increased by around 12% to 10.3 deaths per 100,000, equivalent to around 80,000 additional deaths. Estimates from the World Health Organization also show a similar increase.

This increase is largely attributed to disruptions in malaria prevention, diagnosis, and treatment. The increase was most noticeable in Africa, where IHME estimates that around 95% of malaria deaths occur.

The world has seen big gains in life expectancy in recent decades, yet the United States increasingly lags behind peer countries.

Before the COVID-19 pandemic, the period life expectancy in the US was two years lower than the average for high-income countries, according to data from the UN World Population Prospects.

Healthcare spending as a share of GDP is much higher in the United States than in peer nations. This raises questions about equality in access to care, affordability, and the overall efficiency of the US healthcare system.

Other lifestyle and societal factors are also likely to play a role: the US, for example, has seen a surge in drug-related deaths in recent years as a result of the opioid crisis.
