The 69-year story
Rainier first appears in the Social Security records in 1956, when 11 boys received the name. Its all-time peak is essentially right now: 2023, with 41 babies and a rank of #3005. Names at their peak can keep climbing — or be one trend cycle from the long slide that eventually hits most popular names.
