Wait what? That seems insanely high even for a progressive society.
As a reference point UK is at 30% on YEARLY STATS NOT MONTHLY
>In England, 30% of adults aged 16 and over used a public library service at least once in the previous 12 months.
The soft-play area was heaven for him, and he liked flicking through the donald-duck comic books.
Even now, when he's nine, I go every month or two with him for an afternoon. He has no shortage of books at home, but he gets to run around, look at books, and play with other kids. He enjoys himself enormously.
On one hand, you have a lot of busy and tired adults and a lot of old people that might not use libraries (often), but you also have the massively active younger demographics. I don't know how that would balance out and how the stats were counted. Maybe they fit somehow.
I will say it’s very very common for folks to use the library for its primary purpose of renting books - which of course requires a visit twice in a month - once to collect and once to return.
