Global life expectancy rise
Our World in Data's line chart drew 48.2K views on X: 1.7x its typical post and #49 of 139 Our World in Data charts we track by views. Read Oct 10, 2026.
Global average life expectancy has more than doubled since 1900, We can expect to live more than twice as long as our ancestors in 1900.
Why it spread
It spread because the post paired a self explaining line chart with a striking claim, drawing 355 likes, 110 reposts, 26 quotes, 53 saves and 48,225 views, with a quote rate in the top quarter.
What worked
- The post explains itself, stating the global average life expectancy was just 32 years at the beginning of the 20th century and that it more than doubled by 2023.
- The chart is a simple line with high self labelling and a visible source line, making the trend easy to grasp at a glance.
- The account is branded and the source reach is in the top quarter, giving the post credibility and a wide initial audience.
What to borrow
We could use a clean line chart with high self labelling and a source line, then write a short post that states the starting value and the doubling or other large change in plain words.
Careful
Do not over read the quote rate or assume the same numbers will apply to our account, and avoid copying the exact framing without checking our own data.
