Jaywalking is illegal pretty much everywhere in the US, but enforcement is very selective and regional.
Just checked it for Germany, sensibly it's fined if you walk on the Autobahn or some other street limited to cars only. Crossing any other street - even if there is a crosswalk nearby - will only be fined if you at least create a danger for someone else. And then it's all <= 10€.
