How rare is that?
👶 Born a triplet
1 in 1,000 of US births
One person in a crowd of 1,000. About one in a thousand births.
Too rare to show on a grid of 100: one person in a crowd of 1,000.
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.
