The majority of the world today is poor: 85% of the world live on less than $30 per day. If we are to alleviate global poverty, we need economic growth.

There was a marked acceleration in deforestation in the 20th century. But, global deforestation peaked in the 1980s. Since then, it has slowed.

Over the last 10,000 years the world has lost one-third of its forests. An area twice the size of the United States. Half occurred in the last century.

Israel has been vaccinating its population the fastest against COVID-19. Track how the pandemic in the country is evolving.

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.

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 workers 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.
