1920–1929 · 32,468 recorded births
Robert was the most common name given in Wyoming across the 1920s, with 1,301 births in the decade. The state recorded 32,468 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.
