In 2025, 54 babies in England and Wales were named Louisa. In the US, 369 were, though that figure is from 2017 — the most recent full year we hold.
Looking further back: between 1880 and 2008, Louisa was most common in 1880, when it went to 0.13% of American babies of that sex. Squarely vintage-revival territory.
