1940–1949 · 121,107 recorded births
James was the most common name given in North Dakota across the 1940s, with 2,926 births in the decade. The state recorded 121,107 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.
