Italy has become much safer over the last thirty years.

In the early 1990s, there were around 3 homicides per 100,000 people every year. That was one of the highest rates in Europe.

Since then, rates have fallen by more than 80%. As you can see in the chart, they have been around 0.5 per 100,000 in recent years. That now makes Italy safer than many of its European neighbours.

Mafia-related homicides dropped dramatically in the 1990s following intensified efforts from the Italian government. Some of this organized crime may have also shifted from violent acts towards financial and “white collar” crime.

While estimates can vary across data sources, for Italy, they show strong agreement →

If you live in the same country as your family, you don’t usually have to pay a fee when you send them money. International migrants face a harsher reality: they pay hefty transaction costs when supporting family back home. Globally, the average fee in 2023 was 6.3%, more than double the UN Sustainable Development Goal's target of getting this down to 3%.

This may not sound like much, but migrants send large amounts home to help with schooling, medical bills, house maintenance, and food. The total sum was nearly three times larger than global foreign aid in 2023. (Here, foreign aid consists of net development assistance from national governments and private philanthropy that meets the necessary conditions.)Although 6.3% might seem modest, when applied to large volumes of money, these transfer fees amount to tens of billions of dollars.

The chart shows that migrants lost $51 billion in transaction fees in 2023, which is not far from the $66 billion the US gave as foreign aid. That's $51 billion paid by migrants but never received by their families.

With the new US administration projected to cut aid by more than half, aid experts from the Center for Global Development suggest reducing fees could help fill some of the gap. They recommend promoting cheaper transfer options, increasing competition between services, and linking banking systems across countries.

While money sent home by migrants isn’t as targeted to vulnerable groups as aid, most of it flows directly to families in low- and middle-income countries who can use it for what they need most.

Foreign aid has saved and improved millions of lives through health programs, food aid, and humanitarian assistance. Several countries — including the United States and the United Kingdom — have announced large cuts to their foreign aid budgets in the last few months. However, one country has been moving in the opposite direction in the last five years.

Since 2018, the amount Japan gives in foreign aid has more than doubled. You can see this in the chart.

In 2018, Japan gave $8.6 billion. By 2023, this had increased to $19.3 billion. This makes Japan’s aid budget equivalent to 0.44% of its gross national income. That was more than the United States, which gave 0.24%, but still less than many European countries, including the UK, France, Germany, and Norway, which topped the list at 1.1%.

In the early 1980s, Nepal’s children suffered from some of the highest death rates from pneumonia in the world, with over 1,400 deaths for every 100,000 children under five. That meant around 39,000 children died from pneumonia each year, more than from any other cause.

Since then, Nepal has made huge progress. The death rate has fallen almost 20-fold. This improvement is due to various measures, including pneumococcal and Hib vaccines, better access to healthcare and antibiotics, and improved nutrition.

Despite this progress, pneumonia is still among the leading causes of death in children in Nepal. And we know that more progress can be made: high-income countries have achieved much lower rates, with fewer than 5 per 100,000.

When we think about money flowing from richer to poorer countries, foreign aid is one of the first things that comes to mind.

However, another major channel receives far less attention in mainstream conversations: the money international migrants send back to their families or bring home after working abroad. Unlike aid, which is publicly funded and often targeted at structural development, these private transfers typically aim at family support to cover critical needs such as food, healthcare, and education.

This chart shows how big that contribution is: in 2023, migrants sent or brought back $822 billion, almost three times the $288 billion provided through global foreign aid. Global foreign aid refers to net development assistance from national governments, with a very small portion coming from private donor philanthropy that meets the criteria for development assistance.

While this gives us a good sense of the size of these different flows, it’s important to note that the distribution of where each goes tends to differ. Most of the money sent home by migrants goes from high-income to middle-income countries, but low-income countries also rely on them relative to their GDP. When it comes to foreign aid, low-income countries receive almost as much money as middle-income countries.

Global military spending reached its lowest point of $1.2 trillion in the late 1990s. Since then, military spending has more than doubled, reaching $2.7 trillion in 2024.

The chart shows a drop in military spending after the Cold War ended in 1989. This freed up resources for public expenditure in other domains, sometimes called the “peace dividend”.

But global military spending surged again in the 2000s, partially driven by US spending for the wars in Iraq and Afghanistan, reaching $2 trillion by 2010. After stabilizing for a few years, it has risen sharply in recent years, fueled in part by the war in Ukraine.

Despite these increases, military spending as a share of GDP remains lower than in 1988 in most countries, as economies have grown substantially over this period.
