It’s not just about child mortality, life expectancy improved at all ages
It’s often argued that life expectancy across the world has only increased because child mortality has fallen. But this untrue. The data shows that life expectancy has increased at all ages.

Sector by sector: where do global greenhouse gas emissions come from?
Globally, we emit around 50 billion tonnes of greenhouse gases each year. Where do these emissions come from? We take a look, sector-by-sector.

Where do global greenhouse gas emissions come from?
→ 73.2% from energy
→ 18.4% from agriculture, forestry, land use
→ 5.2% direct industry
→ 3.2% from waste
Our latest article looks at global emissions, sector-by-sector.

COVID-19 per million: Daily new confirmed cases vs cumulative cases
Shown on the y-axis is the 7-day rolling average of daily confirmed cases.
Daily new estimated infections of COVID-19
Mean estimates from epidemiological models of the true number of infections. Estimates differ because the models differ in data used and assumptions made. For comparison, confirmed cases are infections that have been confirmed with a test.
Economic decline in the second quarter of 2020 vs rate of confirmed deaths due to COVID-19
The vertical axis shows the number of COVID-19 deaths per million, as of August 30. The horizontal axis shows the percentage decline of GDP relative to the same quarter in 2019. It is adjusted for inflation.
Which countries have protected both health and the economy in the pandemic?
Responses to the pandemic have often been framed in terms of striking a balance between protecting people’s health and protecting the economy. There is an assumption that countries face a trade-off between these two objectives. But is this...

Response to the pandemic has often been framed as a trade-off between protecting health and the economy.
This isn't reflected in the latest GDP data.
As @JoeHasell explores: countries with the lowest death rate have also performed better economically.

Exemplars in Global Health: Which countries are most successful in preventing maternal deaths?
830 women die from pregnancy-related causes on any given day. Most of these deaths are preventable. How can we use the Exemplar framework to identify which countries have been most successful in doing so?

Our World in Data
The @exemplarshealth platform tries to learn from successful countries in health.
We previously looked at effective country responses to COVID-19.
Now @_HannahRitchie applies this approach for identifying success stories in preventing maternal deaths.

Excess mortality during COVID-19: The number of deaths from all causes compared to previous years
Shown is how the number of weekly deaths in 2020 differs (as a percentage) from the average number of deaths in the same week over the previous five years (2015–2019). This metric is called the P-score.

Our work on the COVID-19 pandemic [ourworldindata.org/coronavirus] now includes regularly updated data on excess mortality.
For many more countries than these three.

How epidemiological models of COVID-19 help us estimate the true number of infections
A key limitation in our understanding of the COVID-19 pandemic is that we do not know the true number of infections. Instead, we only know of infections that have been confirmed by a test – the confirmed cases. But because many infected people never...

We know that confirmed COVID cases are just a fraction of the total.
How do we estimate the true number of infections?
In our latest post @charliegiattino details how different epidemiological models are used to improve our understanding of the pandemic

Exemplars in Global Health: Learning from the most successful countries in the world
Much of our recent work at Our World in Data has focused on the Coronavirus pandemic. As in all our work our main question is to ask how the world can make progress against the pandemic and early on we focused on the fact that there are very large...

Some countries responded successfully to the pandemic – and more broadly, some are much more successful in protecting their population’s health.
