The story
Cauã comes from the Tupi kaûã, meaning hawk or falcon, which makes it one of Brazil's great Indigenous names. The 2022 census counts 92,215 residents carrying it, median age thirteen, and the curve behind that number is remarkable: 1,089 born in the 1990s, then 49,546 in the 2000s, a forty-five-fold jump in a single decade, with 34,946 more in the 2010s. The actor Cauã Reymond, born in Rio in 1980, arrived well before the wave: the census finds only 178 born in his whole decade, meaning he grew up nearly alone with the name his own country would later fall for at scale. North of the equator the story is just beginning; the name stays rare in American records. The tilde does honest work too: that nasal ã is pure Brazilian Portuguese, a small sound of home for families keeping a connection to Brazil alive in a new place.

Not on the record in Mexico City, Puerto Rico, Canada, Ireland, New Zealand, Scotland and Poland: those registries withhold small counts, so rare uses may sit below their floors.
Not on the Chile record: nametree keeps spellings that reached 5 registrations in some year, so rarer uses are not shown. Not on the Montevideo record for 1940 to 2011: that registry withholds nothing, so this spelling was not given there in those years. Not on the France record: nametree keeps spellings that reached 20 births in some year, so rarer uses are not shown. Not on the South Australia record for 1944 to 2017: that registry withholds nothing, so this spelling was not given there in those years. Not on the Austria record for 1984 to 2025: Statistik Austria publishes every first name down to a single birth, so this name was not given there in those years (before 2010 the record covers babies with Austrian citizenship only). Not on Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
