Where Sir sits on the popularity scale
Chance at least one other child shares the name
If the other children were drawn at random from the 2025 national name distribution. Real classrooms cluster by region and community, so treat these as a floor, not a ceiling.
Put another way: gather 34,818 children born in 2025 and it's an even bet that one of them is another Sir. In a class of 30 the chance is Under 1%.

Shading is the share of that state's recorded boys given this name, not the raw count — otherwise the map would just show which states are biggest. Unshaded states have no published records for this period. U.S. birth records suppress state-year counts below 5; state counts therefore don't add up to the national total. Every state links to its full rankings.
