The story
Louie is the pet form of Louis that stopped asking permission. In England and Wales the 2024 rankings put Louie 28th and Louis 47th: the nickname now outranks the name. Its cultural anchor is three chords long: Richard Berry wrote Louie Louie in 1956, the Kingsmen recorded it in 1963, and the vocal came out so gloriously unintelligible that the FBI spent 31 months investigating the lyrics before concluding it was unable to interpret any of the wording. The American record kept Louie steady for a century, about 4,200 boys in the 1920s, and after a long fade it has turned again: 1,907 in the 2010s, then 2,502 so far this decade, already past the full decade before it. Some names need formality to survive; this one thrives precisely because it sounds like someone you already know.

The shares are SSB’s own, of the people of that sex and year in that count; the 2025 figure counts the children named that year, and no year is a count of births.

In Austria, 22 boys named Louie were born in 2025, the 265th most common name among boys that year, spellings that differ only by special characters counted together.
share of that year’s births on record
Live births in Austria by year of birth, 1984–2025, from Statistik Austria’s first-name statistics; spellings that differ only by special characters are counted together (umlauts stay apart), every name down to a single birth is published, and the count covers babies with Austrian citizenship only until 2009, every baby from 2010, and from 2015 also births abroad to mothers living in Austria. Shares divide by Statistik Austria’s count of live births from 2010, and before that by the file’s own total for the year.

Poland

In Poland, 3 boys named Louie were born in 2025, the 581st most common name among boys that year.
The count never rose above 3 in a year, too few to chart.
First names given to children born in Poland by year of birth, 2000–2025, from the PESEL population register (Ministry of Digital Affairs); exact spellings count separately (Łukasz and Lukasz are different names), names given fewer than 5 times in a year were left off the list through 2012 and fewer than 2 times from 2013, and the register also counts children born abroad, so its yearly sums run above Poland’s live births. Shares divide by the register’s own published total for the year, never by births. Source: Ministry of Digital Affairs, PESEL register (dane.gov.pl)

Counts are lower bounds (names under 6 in a month and borough are removed at source) and count name-instances, not people; compound names are split, so “Maria Jose” counts under each part. 2023, a partial extract through 3 Mar with no cell on record for this name, is excluded.

Not on the record in Argentina and Puerto Rico: 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.
