The 143-year story
Rhea first appears in the Social Security records in 1882, when 7 girls received the name. Its all-time peak is essentially right now: 2023, with 577 babies and a rank of #527. Names at their peak can keep climbing — or be one trend cycle from the long slide that eventually hits most popular names. Following the curve matters more than today's snapshot: a name's position on its rise-peak-decline arc is the best predictor of how common it will feel in a kindergarten class five years from now.
