I read in a book about China by New Yorker magazines China expert [1] and he said that up to a third of Chinese citizens are either party members, part of youth groups, or work directly for a CCP owned company.

So it’s not everyone but it’s a lot. The actual CCP membership itself is much lower though. It’s more like an octopus in their society.
