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.

According to the most recent data from the Energy Institute’s Statistical Review of World Energy, India now consumes more coal than the continents of Europe and North America combined.

The chart shows this was not the case until recently. Coal consumption in Europe and North America was high for a long time but has significantly decreased in recent decades. At the same time, India’s consumption has steadily increased.

India has industrialized and is growing rapidly. It has a huge demand for cheap energy, and the country’s abundant coal reserves are being used to meet it.

On a per-capita basis, coal consumption in India has only just passed levels in either region. That’s after centuries of higher consumption in North America and Europe.

In many countries, there are large differences in voter turnout between young and older people. The chart shows the data for recent national elections in four countries.

In the 2022 French elections, 76% of those aged 18–24 voted, while 92% of people aged 50–59 did — a difference of 16 percentage points.

We see the same pattern in the UK and the US. Only slightly more than half of young people voted in their 2019 and 2020 elections, while around three out of four older people did.

This data comes from post-election surveys by Insee, the British Election Study, the US Census Bureau, and the Federal Returning Officer of Germany.

Death rates from illicit drugs are the highest in the United States. This is largely the result of a steep rise in opioid deaths in recent years.

This map shows death rates from opioid overdoses, measured as the number of deaths per 100,000 people in each country’s population. This data comes from the Institute for Health Metrics and Evaluation’s latest Global Burden of Disease study.

In 2021, the United States had, by far, the highest death rate from opioids, with 15.4 deaths per 100,000 people each year. Second behind it was Canada, with 6.9 deaths per 100,000. Several European countries and Russia counted between 3 and 4 deaths per 100,000.

This is not only the case for opioids: the US also has the highest death rate from amphetamine and cocaine overdoses.
