The facts are out (mostly*). Sweden's Frans is the youngest this year (born December 19, 1998) followed by Germany's Jamie-Lee (born March 18, 1998) and San Marino's Serhat is the oldest (born October 24, 1964).
The 1990's dominate the decades with 25 artists born in that decade, followed by 1980's with 22 - that's 94%. *
In the 1970's we have only Ireland's Nicky Byrne (born October 9, 1978), and in the 1960's besides beforementioned Serhat Macedonia's Kaliopi (born December 28, 1966)*
Surprisingly October is the month with most births (9) followed by the spring childs: March (6), February (5) and April (5) but strangely no one celebrates birthday in May!*
Male dominate with 38 vs 26 artists (including the bands from Georgia, Cyprus and Greece).
We have 22 female vocalists against 14 male, but out of the six groups and one duo five have male vocalists so it's in the end 22 vs.19 plus two mixed group vocals (Bosnia & Herzegovina and Greece). This could be the most even set ever for male/female, am I mistaken? As Eurovision tends to be usually very female lead vocally.....
*Please note the data from the bands from Greece, Georgia and Cyprus in not included as not found. If you have those dates, please let me know :-)
