For some reason I was surprised by how old some of the jury members were, don't know why. But I did look at the numbers and found some things out. The youngest member is 16 years old from FYR Macedonia, and the oldest member is 81 years old from Russia. Then I averaged all the ages of all the jury members per country and they are ranked here from youngest to oldest:
1. Spain: 29.2
2. Switzerland: 29.8
3. Malta: 31.4
4. Sweden: 32.2
5. Slovenia: 34.8
6. Georgia: 35
7. San Marino: 35.2
8. Ireland & Latvia: 35.4
10. Moldova: 35.8
11. Finland: 36.8
12. Croatia: 37.2
13. Armenia: 38.2
14. Germany: 38.4
15. Austria: 38.6
16. Belarus: 38.8
17. Cyprus: 39.4
18. Macedonia: 39.8
19. United Kingdom: 40.2
20. Montenegro: 40.4
21. Lithuania: 40.6
22. Belgium: 41.2
23. Norway: 41.4
24. Estonia: 43.4
25. Iceland: 43.6
26. Italy: 43.8
27. France: 44
28. Australia: 44.4
29. Bosnia & Herzegovina: 44.6
30. Poland*: 45.5
31. Hungary: 45.6
32. Israel: 45.8
33. Ukraine: 46
34. Bulgaria, Russia, Serbia: 46.2
37. Denmark: 47.6
38. Azerbaijan: 47.8
39. Netherlands: 50.8
40: Albania: 51
41: Czech Republic: 51.6
Greece hasn't announced their jury yet so no information on that yet.
* Poland has not announced their 5th member, so it should change soon
I clearly has too much time on my hands, but I hope you enjoy this!
