HIV/AIDS deaths by age
Our World in Data's area chart drew 118.9K views on X: 2.0x its typical post and #17 of 139 Our World in Data charts we track by views. Read Oct 10, 2026.
One thing I admired Americans for was they provided efficient and effective aid for people around the world.
Why it spread
This post from @MaxCRoser on 2025-02-17 spread because it paired a hot topic that week with an independent author, reaching 118,931 views, 866 likes, 149 reposts, 13 quotes, and 89 saves.
What worked
- It led with a personal, admiring framing about American aid rather than a dry statistic, which made the numbers feel like a point of view.
- It anchored the message in two concrete figures, about 25 million lives saved and at least 5.5 million babies protected, giving readers something specific to react to.
- It came from an independent author on a hot topic that week, and the source reach landed in the top quarter, helping it travel beyond the account's usual audience.
What to borrow
We could open with a short personal or values-based line, then support it with two or three of our own headline figures, and time the post to a topic already drawing attention that week.
Careful
Do not over-read the quote rate, which sat in the bottom quarter, and do not assume the same framing will work for every chart or that the personal tone alone drove the spread.
