Wildlife population trends
Our World in Data's stacked bar chart drew 7.7K views on X: 0.1x its typical post and #139 of 139 Our World in Data charts we track by views. Read Oct 11, 2026.
My colleague Hannah Ritchie has published a brief guide to the new 'Living Planet Index' report that just got published today.
Why it spread
This post spread because it was carried by an independent author and a big source, reaching the top quarter of source reach and 7,671 views, with 25 likes, 9 reposts, 9 saves wiped out by 0 quotes and a quote rate in the bottom quarter.
What worked
- It points readers to a named colleague, Hannah Ritchie, who is an independent author, which lends the post a trusted human voice.
- It ties the chart to a big source, the newly published Living Planet Index report, giving the post timely news value.
- It uses a short, plain framing that simply says a brief guide is available and links to it, which keeps the ask low and the focus on the chart.
What to borrow
We could pair our own chart with a short pointer to a named colleague or author and a big, timely source, then let the chart itself carry the message instead of over-explaining it.
Careful
Do not over-read the low quote rate or the modest likes and saves as proof the chart failed, since the post still reached the top quarter of source reach and 7,671 views, and do not assume the same framing will work without a big source behind it.
