Globally, the share of the population living in extreme poverty has declined fast, from 38% in 1990 to 9% in 2024.
Some countries, however, have not made any progress against poverty. Four of them are in Southeast Africa, as shown in the chart. In Zambia, Malawi, Mozambique, and Madagascar, most people still live in extreme poverty, and this hasn’t changed in decades.
Poverty has remained high because these economies have not achieved economic growth in recent decades.
In the 1990s, most extremely poor people lived in countries that went on to have strong economic growth. Today, however, a substantial share of the poorest people live in economies that have not grown in decades. Based on current trends, this means that the world cannot expect an end to extreme poverty.
Whether or not the economies that are home to the poorest people in the world start to grow will determine whether the world ends extreme poverty.
I’ve written more about this in “The history of the end of poverty has just begun”, where I explain why economic growth is key to ending poverty →

It’s hard to imagine anything more terrifying than your baby contracting HIV. This is the reality for around 130,000 families every year.
Just a few decades ago, this figure was over half a million. Most of these infections were passed on from mothers who had HIV themselves.
But the introduction of anti-retroviral (ART) drugs and other interventions has meant that most infections can be prevented. If the mother takes ART during pregnancy, it dramatically reduces the risk of passing on HIV. In some cases, giving ART to the baby in the first few weeks of life can help too.
In the chart, you can see this decline in new HIV infections in children. On top, you can see the huge number of cases estimated to have been averted thanks to these interventions; they amount to almost a quarter of a million cases every year.

Global trade has never been a bigger slice of the world economy. However, China, the country that most people think of as the export giant, has seen a decline in its trade-to-GDP ratio in the last 15 years.
The chart shows China’s trade in goods and services as a share of its Gross Domestic Product (GDP). In 1970, it was just 5%. Following Deng Xiaoping's economic reforms, which opened China to market forces and international trade, this figure soared to 64% in 2006. But since then, it has fallen considerably, reaching 37% in 2023. China's exports have grown in dollar terms, but its economy has expanded even faster, making trade a shrinking share of the whole.
While the 2008 financial crisis disrupted global trade, China’s trajectory also reflects the increase in domestic demand for its production. For years, Chinese officials have advocated rebalancing the economy away from export dependence and toward one driven by domestic consumption. A rising middle class now buys more of what China produces, reducing its reliance on international markets.

In the late 1990s, Sri Lanka had one of the highest suicide rates in the world: three times the global average and four times the rate in countries like the United States or the United Kingdom.
The most frequent method of suicide was self-poisoning, particularly from pesticides.
But since then, suicide rates have fallen by almost two-thirds. You can see this in the chart.
The biggest driver of this improvement was the banning of particularly toxic pesticides. Two highly hazardous pesticides were initially banned in 1984, and five more were banned in 1995. This slowed the growth in suicide rates, and the trend eventually turned the corner into a strong decline.
Sri Lanka’s experience in the last few decades makes it clear that suicide rates are not “fixed” at a particular level, and there are things that can be done to reduce them.

How many hours have you used electricity today? For me, it’s probably all of them — from charging my phone overnight to working on my laptop, exercising with my watch, and listening to music through my earphones. It's so normal that I can't imagine life without it.
But life without electricity is a reality for millions in Sub-Saharan Africa. This map shows the share of people with access to electricity across the region. This is defined as having a source that can provide basic lighting, charge a phone, or power a radio for just 4 hours daily.
Look at the countries in dark red: in Chad, only 12% of people have access. In the Democratic Republic of Congo — a country of over 100 million people — it's just 22%. Overall, 85% of people worldwide who lack access to electricity now live in Sub-Saharan Africa.
There are bright spots, though. Countries like Kenya, where more than three-quarters of people now have electricity, show that progress in the region is possible.

Most of us have heard that smoking damages the lungs. The chart drives this home: in the US, men who smoke are around 21 times more likely to die from lung cancer than men who have never smoked.
But the damage doesn’t stop there: smoking also increases the risk of other cancers, including mouth, throat, bladder and pancreatic cancer, in addition to other health conditions such as chronic obstructive pulmonary disease (COPD), heart disease, and diabetes.
Why does one habit harm so many organs? Cigarettes carry a mixture of carcinogens that reach — and damage — tissues throughout the body. Smoking also injures blood vessels, fuels inflammation, and makes it easier for tumors to spread.
Because a single behavior poses so many risks, cutting smoking rates has been one of the most powerful tools to save lives and improve public health.

In 1990, one in four newborns in Malawi died before their fifth birthday.
At that time, the average number of births per woman was almost seven. This meant that many families experienced the tragedy of losing a child.
But in recent decades, Malawi has made incredible progress. As you can see in the chart, the child mortality rate has dropped to 1 in 25 children — an 84% reduction.
Many factors have contributed to this decline. The expansion of antenatal care and the attendance of skilled health professionals at birth have been crucial in saving newborns in the earliest days of life. Increasing vaccination rates, distributing insecticide-treated bed nets and antimalarials, and programs to stop the transmission of HIV have all reduced the risks of dying in infancy.
