When asked where public spending should be reduced most, around 60% of people in the UK suggest cutting foreign aid.
However, people overestimate how much the UK spends on aid: last year’s UK Public Expenditure Statistical Analyses show that overseas aid amounted to £5.1 billion — just about 74 pounds per person.
As the chart shows, this is a tiny part of public spending, making up only 0.5% of the total budget.
To put this in perspective, the UK spends much more on other areas: over eight times as much on public order and safety, ten times more on defense, and forty times more on each of the two biggest expenses: health and welfare.
Spending is not much higher if we also consider funds dedicated to supporting refugees in the UK itself.
This situation is not specific to 2023: the UK’s foreign aid spending has been at similar levels for decades and is in line with what other wealthy countries spend. Compared to the size of its budget and economy, foreign aid is a relatively small expense.

At the turn of the millennium, 2.2 billion people in the world lived in extreme poverty. In international statistics, this means they survived on less than $3 per day (in today’s money).
In the two decades that followed, this number more than halved. You can see this decline in the chart.
This huge reduction was driven by rising incomes and poverty alleviation across East and South Asia. In Sub-Saharan Africa, the opposite happened: while the share living in extreme poverty declined, the total number increased.
Looking ahead, based on the latest available projections from researchers at the World Bank, this reduction in global extreme poverty is expected to end. In fact, numbers in 2040 might be higher than they are today.
This is because most of the extremely poor today live in countries with stagnant economies. If these do not see much stronger economic growth, the world will have nearly one billion living in dire poverty for decades to come.
Note that these projections are based on the latest growth projections from the World Bank and the IMF. From 2031 onward, poverty projections are based on the average growth rates observed from 2015 to 2024.

Just a decade ago, almost three times as much electricity in the European Union was coming from fossil fuels as from solar and wind.
But last year, for the first time, solar and wind produced more than coal, gas, and oil combined. They accounted for just over 30% of total electricity production.
You can see this rise of solar and wind — and fossil fuels’ decline — in the chart.
This record happened despite a poor year for wind output due to low wind speeds and a slight increase in gas to compensate for lower hydropower output from dry conditions.

Marriage is closely linked to decisions about having children in many societies. It also matters for legal rights, family finances, and many other aspects of life.
The age at which people marry has rapidly changed in many countries. The chart shows this by tracking the average age at first marriage among women, using records from national statistics.
In Portugal, Italy, and Spain, the average age at first marriage has risen rapidly and consistently. Portugal saw the largest increase: from around 26 years in 2002 to over 32 years by 2020. This is more than six years in less than a generation. It’s also the largest increase among the countries in the OECD Family Database with data available from the early 2000s up to 2020 (the most recent year with available data in the series).
Changes in the timing of marriage have come together with other related shifts. For instance, a growing share of people are not marrying at all.

4,510 objects were launched into space in 2025, surpassing the previous peak of 2,903 objects in 2023 by a large margin.
The data shows that US agencies and companies were responsible for launching 3,708 of these objects — 82% of the global total.
The vast majority of these American launches consist of small satellites deployed as part of large commercial “constellations”. These interconnected networks of satellites now account for the bulk of all objects sent into orbit.
The rapid growth of satellite constellations makes it possible to expand Internet connectivity, but it also increases concerns regarding space debris and the congestion of Earth’s orbital environment.

In the 1970s, oil spills from tankers — container ships transporting oil — were common. Between 70 and 100 spills occurred per year. That’s one or two spills every week.
This number has fallen by more than 90% since then. In the last decade, no year has had more than ten oil spills, as shown in the chart.
The quantity of oil spilled from tankers has also fallen dramatically. Over the last decade, the average is less than 10,000 tonnes per year, compared to over 300,000 tonnes in the 1970s.

In the past, forests around the world were cut down on a massive scale. We lost some of the world’s richest ecosystems.
In recent decades, the picture has become more complex. Deforestation has not ended, but it is no longer happening everywhere. Since 1990, some regions have continued to lose large areas of forest, while others have slowed this long-run trend — and even reversed it.
The map shows regional changes in forest area based on the latest data from the Food and Agriculture Organization of the United Nations.
Deforestation has been particularly large in South America and Africa. At the same time, the forested area has expanded in Europe, North and Central America, and large parts of Asia.
These gains show that deforestation is not inevitable. When pressure on land falls, forests can return.

The Netherlands was the first country to legalize same-sex marriage in 2001. Since then, almost 40 other countries have followed suit.
You can see this in the chart, based on data from Pew Research. By 2025, same-sex marriage was legal in 39 countries.
Last year, two countries were added to the total. Thailand became the first country in Southeast Asia to legalize same-sex marriage, and a same-sex marriage bill also took effect in Liechtenstein.
