One Rio, two histories

The story
Rio means river in Spanish and Portuguese, and Rio de Janeiro carries the phrase January River. The familiar account says early explorers reached its harbor in January and mistook it for a river mouth. A separate Japanese name shares the spelling and can be formed from several kanji combinations, so one written Rio does not imply one origin. In the US record, scattered entries appear for decades; girls first exceed one hundred in the 1980s. The recent curve is larger and increasingly male: about 1,800 children appear in the 2010s and 3,560 so far this decade, nearly twice the complete 2010s total. Across the published series there are about 5,500 boys and 2,300 girls. The chart can count American records; it cannot untangle the languages meeting in those three letters.
