In 2023, Norwegians gave $1,160 in foreign aid — more than twice the amount contributed by people in other large Western countries.
By comparison, people in countries like the United States and Japan gave much less, at $190 and $155 per person, respectively.
One factor behind Norway’s substantial foreign aid is its sovereign wealth fund, built from oil revenues. The fund is valued at around $1.8 trillion — about the size of the Australian economy — and provides financial resources that few nations can match.
Still, its generosity stands out: Norway also leads in foreign aid as a share of national income.

Almost one-quarter of adults in the world smoke tobacco. However, there are significant differences by gender.
More than one-third of men smoke, while less than one in ten women do.
Men are more likely to smoke in almost every country in the world. You can see this on the chart, which plots the share of men who smoke versus the share of women. Nearly all countries lie above the diagonal line, which means more men smoke than women.
This data is collated and published by the World Bank. It’s based on adults aged 15 years and older and includes all tobacco products.

Childhood cancer deaths in the United States have fallen dramatically over time, as shown in the chart. It presents annual cancer death rates in children under five years old.
There has been a six-fold decline since the 1950s.
This progress reflects decades of collaboration between scientists, clinicians, and public health workers.
One major success story has been in treating acute lymphoblastic leukemia, a common form of leukemia in children: researchers identified genetic mutations that caused the disease, making it possible to develop targeted chemotherapy drugs that have greatly improved survival. Surgeries, bone marrow transplants, and other treatments have also played a role.
We’ve also seen big improvements for other blood cancers, such as lymphomas and multiple myeloma, though progress has been slower for cancers of the brain and nervous system.

Record national life expectancies have been climbing for over a century.
In 1840, Swedish women had a life expectancy of 46 years — the highest of any country recorded that year. By 1921, Australia held the record at 63 years.
For most of the 20th century, Iceland, Norway, Australia, and Sweden competed for the top position before being overtaken by Japan in 1984. Hong Kong and Japan have held the records since then.
These countries didn’t merely catch up; they’ve continued to push the limits higher.
Japan added six more years to female life expectancy between 1984 and 2010, rising from 80 to 86 years.
This remarkable rise has resulted from many advances in medicine, public health, and living standards — breaking many predictions of the “limits” of life expectancy.

Since the start of the Syrian civil war in 2011, many people have left the country. By 2020, around 8.5 millions had emigrated, representing nearly half (48%) of all people born in the country.
As you can see on the chart, most Syrian emigrants have stayed close to home. Two-thirds of Syrian emigrants now live in Turkey, Lebanon, or Saudi Arabia, with Turkey alone hosting over 40%.
Political obstacles have made it difficult for Syrian migrants to move beyond neighboring countries and reach Europe. In 2016, the European Union and Turkey made a deal to curb migration by keeping migrants in Turkey in exchange for 6 billion euros in aid.
The Syrian case is part of a larger global pattern: most individuals who leave their country stay in the same continent.

In 1960, Singapore’s GDP per capita — a measure of average income — was a third of the average in Western Europe. It was even lower than Western Europe’s average income in 1900.
Since then, while Western Europe experienced steady growth, Singapore grew even faster. By 1994, it had surpassed Western Europe, and today, its average income is roughly twice as high. This is after adjusting for inflation and differences in living costs between countries.
Singapore became an independent republic in 1965. Key factors in its economic success include anti-corruption policies, investment in education and human capital, and its development as a global financial hub.

China has dramatically reduced local air pollution levels — particularly in its biggest cities — in the last decade.
One rapidly declining pollutant is sulphur dioxide (SO2), which generates smog and can cause acid rain. Its primary source is coal burning.
In the chart, you can see the annual emissions of SO2 in China. They rose steeply during the 1980s and 1990s. But they peaked in the mid-2000s, and over the last 15 years, they have fallen by more than two-thirds.
Putting emissions limits on coal plants and introducing desulphurization technologies that remove SO2 from smokestacks were critical drivers of this decline.
These are modeled estimates from the Community Emissions Data System (CEDS).
