Every twelfth person in the world still lives in extreme poverty. That means surviving on less than $2.15 per day (adjusted for differences in living costs between countries).
For many, that means struggling to afford nutritious food, not being able to afford basic healthcare, safe sanitation, or electricity.
So, where do most people in extreme poverty live? The chart shows that Sub-Saharan Africa, which is home to just 16% of the global population, now accounts for 67% of people living in extreme poverty.
This distribution is very different from 25 years ago. In 2000, Asia was home to most of the world’s population living in extreme poverty. However, strong economic growth in recent decades has led to steep reductions in poverty. Progress in Sub-Saharan Africa has been much slower.
If we're serious about ending extreme poverty worldwide, supporting economic development in Sub-Saharan Africa has to be a top priority. The recent progress achieved by some African countries reminds us that meaningful change is within reach.

Globally, more than 700,000 people die from suicide every year.
Understanding the factors that increase the risk of suicide can help us provide the most effective interventions and support systems.
One thing we do know is that more men die from suicide than women. In the chart, you can see male suicide rates (on the vertical axis) plotted against female rates. One dot is one country. Since all of the dots lie above the line, male suicide rates were higher in all countries included in this dataset.
The size of this gender gap varies by country. In the United States, rates among men are four times higher than amongst women. In South Korea and Japan, they’re around double. Some countries lie closer to the line, meaning the gap is smaller.
The exact reasons for this gender gap are still debated. Factors could include the lethality of different methods, stigma around seeking help, different social pressures, and alcohol and drug abuse.
Every suicide is a tragedy. However, suicide death rates have declined in many countries, and we know that they can be reduced further with greater understanding and support. If you are dealing with suicidal thoughts, you can receive immediate help by visiting resources such as findahelpline.com.

Famines are still a major global problem. From 2020 to 2023 alone, they caused over a million deaths.
Yet the long-term trend shows significant progress. In the late 1800s and the first half of the 1900s, it was common for famines to kill over 10 million people per decade. This was true as recently as the 1960s, when China’s Great Leap Forward became the deadliest famine in history.
But as you can see in the chart, that number has dropped sharply, to about one to two million per decade.
This improvement is even more striking given that the world’s population has grown substantially. Despite many more people living on Earth, far fewer die from famines than before.
This progress has resulted from various factors, including increased food production, poverty reduction, fewer conflicts, and more accountable governments.

In 2021, malaria was the leading cause of death among children under five in more than 20 countries in Sub-Saharan Africa.
In Nigeria, over 125,000 young children died from it — that’s 340 every day, one child around every four minutes. The country accounts for one-third of all under‑5 malaria deaths in the world.
Malaria is both preventable and treatable. But millions of children still lack access to basic protection: bed nets, timely treatment, and safe living conditions. We’ve seen malaria eliminated elsewhere.
The tools exist; the challenge is getting them to those who need them most.

Over 100 million infants are vaccinated against measles every year, which means more than 80% of one-year-olds are protected from this potentially life-threatening disease. This global effort has saved millions of lives.
That scale should be reassuring. Measles vaccines are safe and reduce the risk of infection by over 95%, making them one of our most powerful tools to prevent childhood deaths. Outbreaks have become increasingly rare in many countries, global infant mortality has fallen, and measles vaccination alone is estimated to have saved more than 94 million lives.
But that progress is under threat: vaccination rates have fallen in recent years, as the chart shows, and fewer children are getting the protection they need. When coverage slips, measles spreads rapidly; more children suffer and die from a disease we can easily prevent.

How will artificial intelligence (AI) impact people’s jobs?
This question has no simple answer, but the more AI systems can independently carry out long, job-like tasks, the greater their impact will likely be.
The chart shows a trend in this direction for software-related tasks. The length of tasks — in terms of how long they take human professionals — that AIs can do on their own has increased quickly in the past couple of years.
Before 2023, even the best AI systems could only perform tasks that take people around 10 seconds, such as selecting the right file.
Today, the best AIs can fairly reliably (with an 80% success rate) do tasks that take people 20 minutes or more, such as finding and fixing bugs in code or configuring common software packages.
It’s unclear how much these results generalize; other factors, like reliability, need to be considered.
But AI capabilities continue to improve, and if developments keep pace for the next few years, we could see systems capable of performing tasks that take people days or even longer.

Road transport is responsible for around three-quarters of global carbon dioxide emissions from transport. Switching from petrol and diesel to electric vehicles is an important solution to decarbonize our economies.
This chart shows the change in share of new cars that were electric in China, the European Union (EU), and the United States (US) between 2020 and 2023. This includes fully electric and plug-in hybrid cars, though most are fully electric.
In 2020, electric cars were rare everywhere. But by 2023, over one-third of new vehicles in China were electric, compared to less than a quarter in the EU and under a tenth in the US.
While we only have annual data up to 2023, preliminary figures suggest that in 2024, electric cars outsold conventional ones for the first time in China.

Many previous generations of women in my family would not have been allowed to do the work I do today — even if computers, the Internet, and Our World in Data had existed then. Thankfully, that’s no longer the case where I live: I’ve had the same right to get an education, work, and build a career as my brother.
Unfortunately, that’s not the case everywhere.
The map highlights the countries where women had legal restrictions on their rights to work in formal employment in 2023. All are in the Middle East, North Africa, or Sub-Saharan Africa.
These restrictions can include the need for permission or documentation from a male family member — such as a husband or brother — to work, or legal consequences if they don’t follow working restrictions.
While nearly 20 countries still have these legal barriers for women, this number was much larger in the past: in 1970, it was almost 70.
This data only reflects legal restrictions on working rights. In other countries, strong social or cultural pressures still mean that women are less likely to be in formal employment than men, even if they’re legally allowed to.
