How rare is that?
🪞 Identical twin
1 in 250 of US births
One person in a crowd of 250. One egg, two people. Fingerprints still differ.
Too rare to show on a grid of 100: one person in a crowd of 250.
Each figure stands for one percent of the group. The share is a rounded estimate from public surveys and published studies; the group it refers to is "US births", which is not always the whole world.
