First recorded in 1941, the name reached its peak rank of 10695 in 1942 with a 1-in-284679 frequency, then declined steadily. Its trajectory has been falling since 2017, and it remains rare. The name has never attained widespread usage; top states are minimal, reflecting its niche status. Macarthur carries a strong, historically charged feel, unusual among modern given names.
