1910–1919 · 272,183 recorded births
Mary was the most common name given in Iowa across the 1910s, with 7,107 births in the decade. The state recorded 272,183 births in total over those years.
Names given far more often here than nationally in these years. The multiplier is conservative — it is the low end of the plausible range, so a name carried by a handful of births does not outrank one carried by hundreds.
