Our World in Data's line chart drew 424.1K views on X: 15x its typical post and #4 of 139 Our World in Data charts we track by views. Read Oct 10, 2026.
Until fifty years ago, Argentina was richer than Spain, (This Data Insight was written by @EOrtizOspina.)
Why it spread
It spread because a striking historical reversal about Argentina and Spain, posted by a data journalism account with a branded chart, drew 1,008 likes, 193 reposts, 102 quotes, 212 saves circulating through 424,104 views, with a quote rate in the top quarter and source reach in the top quarter.
What worked
- The post text opens with a concrete, surprising claim that Argentina was richer than Spain until fifty years ago, which gives readers a reason to stop and share.
- The chart is a simple line showing Spain overtakes Argentina in GDP per capita over time, a clear single-message visual with medium design polish, medium self labelling, no unusual form, and a visible source line.
- The framing credits an independent author and pairs the post with a follow up Data Insight, which supports credibility and gives the audience a reason to quote and discuss.
What to borrow
We could take one of our own long run comparisons, state the reversal in the headline as a plain sentence, and let a single line chart carry the evidence with a clear source line and a named author.
Careful
Do not read this as proof that any historical comparison will travel, and do not copy the exact Argentina and Spain framing or assume the same numbers will repeat for our topics.
