Air pollution deaths
Our World in Data's stacked bar chart drew 24.8K views on X: 0.9x its typical post and #89 of 139 Our World in Data charts we track by views. Read Oct 10, 2026.
Millions of people die prematurely from air pollution every year, as you can see in the chart.
Why it spread
It spread because it explains itself and hit a hot topic that week, drawing 24,783 views, 164 likes, 51 reposts, 5 quotes, and 33 saves.
What worked
- The stacked bar chart is self labelling, so viewers grasp the air pollution death toll without extra explanation.
- The post text frames the issue as long standing yet solvable, which matches a hot topic that week.
- The chart is branded and shows a source line, adding credibility that helped it travel.
What to borrow
We could use a self labelling stacked bar for our own data on a timely topic, keep the post text short and solution oriented, and always include our brand and source line.
Careful
Do not over read the quote rate as above average or the source reach as top quarter, since those are relative labels without raw numbers, and do not assume the same results without a hot topic.
