Claims that the world has only 100, 60, or even 30 years of harvests left often hit the headlines. These claims are overblown, but soil erosion is a problem and we can do something about it.

We are building a global dataset on COVID-19 Vaccinations. Explore the latest data for all countries.

To be able to track the development of the pandemic in the UK we built this page in which we are making the local UK data available in six charts. Updated daily.

The primary way to measure working hours is with surveys, but the data can have limitations that are important to understand.

Workers in richer countries tend to work fewer hours than those in poorer countries.

Working hours for the average worker have decreased dramatically over the last 150 years.

In many countries the amount of time parents spend with their kids has been increasing over the last 50 years.

In adolescence we spend the most time with our parents, siblings, and friends; as we enter adulthood we spend more time with our co-workers, partners, and children; and in our later years we spend an increasing amount of time alone.

The world faces two energy problems: most of our energy production still produces greenhouse gas emissions, and hundreds of millions lack access to energy entirely.

How people spend their time is similar in many ways across countries: we all sleep, work, eat, and enjoy leisure. But there are also important differences in the freedom people have to spend time on the things they value most.

Fossil fuels dominate the global power supply because until very recently electricity from fossil fuels was the cheapest. This has changed dramatically. In most places power from new renewables is now cheaper than new fossil fuels.

To continue providing daily updates on the Coronavirus Pandemic, Our World in Data has switched from ECDC to Johns Hopkins University as our data source for confirmed cases and deaths.

For much of human history, our ancestors were trapped in an economy in which incomes were determined by the size of the population. The Industrial Revolution ended this Malthusian economy and made it possible for a country to leave abject poverty behind.

There are two ways that COVID-19 deaths can be presented over time: by the date of death, or the date on which the death is reported. The data for Sweden is shown by date of death – this means the most recent points should be treated as incomplete.

Globally, aviation accounts for around 2.5% of CO₂ emissions. But for many, it accounts for a much larger share.

40% of eligible voters in the US did not vote in the 2016 election. Young Americans in particular often do not exercise their right to vote – less than half of eligible under-30s voted in the last election.

Americans have a lower life expectancy than people in other rich countries despite paying much more for healthcare. We explore the number of factors which might explain this difference.

Aviation accounts for 2.5% of global CO₂ emissions. Where do these emissions come from?

Flying is a highly controversial topic in climate debates. It accounts for around 2.5% of global CO₂ emissions, but 3.5% when we take non-CO₂ impacts on climate into account.

For individuals, transport can be the largest part of their carbon footprint. If you need to travel, what is the lowest-carbon way to do so?

The Our World in Data dataset which has tracked COVID-19 testing across the world since the start of the pandemic has been peer-reviewed and published in the academic journal, Nature.
