than to be hit by a meteorite
Periods differ: Shared birthday (23 people) is framed as group of 23 people, while Hit by a meteorite is lifetime (illustrative). The multiplier is a raw ratio of the 1-in-X figures — not a normalized lifetime risk. Compare cautiously.

How we calculated this
Each figure is “1 in X.” The larger X is the rarer event. Dividing that number by the more common one gives the multiplier: you're 800,000× more likely to share a birthday in a group of 23. When the periods differ, this is a raw ratio of those figures, not a lifetime-normalized risk.
