For decades, the World Values Survey and European Values Study projects have examined people’s values through their surveys. One of the questions on trust asks: “Generally speaking, would you say that most people can be trusted or that you need to be very careful in dealing with people?”
This chart shows the share of respondents who answered “most people can be trusted” across different countries.
As you can see, reported trust in others varies widely from country to country. In the Nordic nations, over 60% of respondents believe most people can be trusted, while in France and Italy, this figure drops to around 26%. At the lower end, as few as 5% of people in countries like Colombia and Peru express trust in others.
It’s worth noting that interpretations of survey-based “trust” measures are complex: what people mean when they answer this question could reflect various ideas about trust, personal experiences, or cultural attitudes toward trustworthiness.

Economic growth is most important for the world's poorest people, and most of the world’s poorest live on the African continent. Are Africa’s economies growing?
The picture is mixed. In some countries, incomes have unfortunately declined in the last decades. This includes Madagascar, Zimbabwe, and Burundi. I have written about this in my brief explainer on extreme poverty.
In today’s Daily Data Insight, I want to focus on the other side: I want to highlight the African countries that are achieving economic growth. Nine of them are shown in the chart above.
In all nine countries, people’s average incomes have more than doubled since 1990.
This made substantial improvements in living standards possible: the share of people in extreme poverty and the rate of child mortality declined in all nine countries.

The US President’s Emergency Plan for AIDS Relief, known as PEPFAR, was established in 2003 to fight the global HIV epidemic.
Since its launch, PEPFAR has provided millions of people with antiretroviral therapy (ART) worldwide, especially in Africa.
The chart shows the number of people who received therapy through PEPFAR in a given year. In 2023, it was 20.5 million people.
ART is highly effective: it helps keep people with HIV healthy and reduces the risk of spreading the virus to others, saving more than one million lives each year.
But, after months of legislative delay, PEPFAR was recently renewed for only one year, raising concerns about the program's future after March 2025.

In today’s Data Insight, we’re sharing a behind-the-scenes look at a part of our work we rarely talk about, but that is crucial in contributing to a more accurate understanding of the world.
We work with hundreds of datasets from many different sources. To check their quality, we’ve built in-house tools that flag unusual patterns, helping us spot when something seems off. Even in high-quality datasets, occasional errors can slip through.
The chart shows a recent example: after we updated a dataset, we noticed an unexpected spike in one of its time series. Investigating further, we traced the issue back to the data provider and let them know. They reviewed it, confirmed the problem, and corrected the error. Thanks to exchanges like this, several datasets have been improved this year.
Improving data quality is always a collaborative effort. We deeply appreciate the work of statisticians and data providers worldwide, who play a critical role in creating and maintaining these datasets. Our role is to help flag issues when we spot them and provide constructive feedback to make the data better for everyone.

For almost all of human history, food was scarce for nearly everyone. The reason for this perpetual scarcity was that whenever food production increased, it did not lead to more food per capita but to more people.
Food production did not increase per capita. Population pressure ensured that living standards remained only barely above the subsistence level. Economic historians refer to this mechanism as the Malthusian Trap, and if you’d like to know more, you could read my article about it.
This changed in the last decades. More and more societies around the world broke out of the Malthusian Trap. We see this in the data as increasing food production in per capita terms. The chart shows that farmers have grown many fruits, vegetables, and nuts faster than the world population has increased.
The increase in global agricultural output was crucial for the reduction of hunger and famines that the world achieved in this period. Whether or not we will be able to end hunger globally will depend on whether this increase in food production will continue.

Around 90% of the world’s carbon dioxide (CO2) emissions come from fossil fuels and industrial processes such as cement production. The other 10% comes from land use change, primarily carbon released from trees and vegetation due to deforestation.
Fossil fuels are also the biggest source of emissions at the national level in most countries across the world. But there are a few exceptions.
In the chart, you can see the share of emissions from fossil fuels compared to land use change across a small selection of countries. In the United States, the United Kingdom, and China, fossil fuels dominate. This data comes from the Global Carbon Project.
However, in Brazil, land use change plays a much more significant role. This is for two reasons. First, deforestation rates are higher than in most other countries. Second, Brazil has a very clean power grid. Most of its electricity comes from hydropower, with solar and wind also growing quickly. It burns very little coal and gas.

The United States is the world’s largest oil producer.
The chart shows annual production by country from 1990 to 2023. The US has been the largest producer for the last seven years.
Production in the US gradually declined during the 1990s and early 2000s but increased steeply again post-2010 and is now at an all-time high.
This data comes from the Energy Institute’s Statistical Review of World Energy.

European neighbors Portugal and Spain are currently neck-and-neck in the race to roll out solar and wind power.
On the chart, you can see the share of electricity from the combination of solar and wind in each country. Their rate of progress has been very similar.
In 2023, both countries generated around 40% of their electricity from these sources. Wind power is more prevalent in Portugal, while solar is more used in Spain.
This data comes from Ember.
