From the answers just from Europeans, parents in the following capitals (not even including smaller cities and towns):

1. Vienna (Austria)
2. Warsaw (Poland)
3. Berlin (Germany)
4. Prague (Czechia)
5. Talinn (Estonia)
6. Ljubliana (Slovenia)
7. Amsterdam (Netherlands)
8. Helsinki (Finland)
9. Dublin (Ireland)
10. Bern (Switzerland)
11. Lisbon (Portugal)
12. Madrid (Spain)
13. Reykjavík (Iceland)
14. Moscow (Russia)
15. Zagreb (Croatia)
16. Copenhagen (Denmark)
17. Baku (Azerbaijan)

And from personal experience this is also perfectly normal for children to explore the city alone in Singapore, Seoul, Tokyo, and Taipei.

And again, I’m just listing the capitals where it’s safe. A comprehensive list would be way too long.

Yeah one of my fav questions on AskEurope was “can a 10 year old girl walk alone to school in your city?”

There are hundreds of cities around the world where people would say “of course. How else do they get to school?”

I cannot think of one single city in the US that is both walkable and safe enough for this.

Maybe Palo Alto, as long as it’s in the same neighborhood so they don’t have to cross a 45mph (70kph) road.

Great to hear! Seems to be mirroring the Euros effect in England, Australia is also producing top players so it’s good to see the growth
