Why it spread
This chart post from @OurWorldInData spread because it explains itself and landed on a hot topic that week, reaching 27,997 views with 327 likes, 45 reposts, 7 quotes and 28 saves.
What worked
- The post is highly self labelling, so the stacked bar makes its point about three-quarters of UK eggs being free-range without extra explanation.
- It pairs the chart with a personal story about growing up in the United Kingdom in the 1990s and early 2000s, which makes the battery hen contrast feel human.
- It shows a source line and comes from a branded account with top quarter source reach, which supports trust in the numbers.
What to borrow
We could take a familiar change over time, show the current share clearly in a stacked bar, and open with a short first person memory that connects our own data to everyday experience.
Careful
Do not over-read the spread as proof of debate, since the quote rate is below average, and do not copy the emotional framing without checking that our own data and sourcing support it.
