Names that work in Spanish and Portuguese

On one side: Spain, Mexico City, Argentina, Puerto Rico, Chile and Montevideo. On the other: Brazil. A name is on this page when it sits at rank 300 or better in the latest list of at least one record on each side, spelled the same way, accents aside, with one exact spelling standing for it in each record. Order: its best rank on one side plus its best rank on the other, lowest first.

There is no world rank here: every figure names its record and its year.

Brazil’s side is the 2022 census, which counts people of every age, so on this page Brazil is a stock of names in use, not a list of births.

Spain’s resident register also counts people of every age; its newborn list is the one that speaks for births.

Where a registry counts each spelling separately, its leading spelling stands for the name across records (Ireland’s Rían stands for Rian); the other spellings keep their own rows and their own counts, and are never added together.
