To be able to track the vaccination campaign in the United States, we are making state-by-state data available in the following charts. We are updating the data daily.

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.

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.

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

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.

The Industrial Revolution ended the Malthusian trap in which incomes were determined by the size of the population — making 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. What factors may explain this?

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

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 Scientific Data.

Transport accounts for around one-fifth of global CO₂ emissions. Three-quarters of this is from road transport.

Millions of people use Our World in Data every month. We looked at survey responses to understand who uses our work, and what for.

A video about the drivers and possible solutions to climate change.

It’s often argued that life expectancy across the world has only increased because child mortality has fallen. But this is untrue. The data shows that life expectancy has increased at all ages.

Globally, we emit around 50 billion tonnes of greenhouse gases yearly. Where do these emissions come from? We take a look, sector-by-sector.
