Thanks for the tag @ckronenberg.bsky.social! RWI has collected some data on county level for childcare fees. We see a lot of variation for under three (left) and less so for 3-6 (right). There is still some data prep in process but it is generally available at: doi.org/10.7807/immo...

There's still some catching up to do for West Germany. Thank you for the post and the helpful comments! It was great meeting you in Dresden!
