All 50 states and DC, sorted by rate. Counts are boys named Colin born
2021–2025; the per-1,000 rate makes states of different sizes
comparable, and the last column shows each state against the national average.
State counts come from the Social Security Administration's state files, which omit any
state-year with fewer than five babies of a name, so small states can undercount slightly.
