FYR Macedonia will make their U21 finals debuts next summer after qualifying for the first time.
Only six teams – Denmark, England, Germany, Italy, Portugal and Sweden – negotiated qualifying without suffering defeat.
Slovakia's Jaroslav Mihalík and Sweden's Kristoffer Olsson assisted six goals each, more than any other player.
There were two seven-goal wins, Austria beating Azerbaijan 7-0 in St Polten and the Czech Republic defeating Malta by the same scoreline in Ta' Qali. Portugal also hit seven on Tuesday, but only after Liechtenstein had taken a shock lead.
Czech Repuplic striker Patrik Schick top scored with ten goals; he needs five more at next summer's finals to match Lampros Choutos's record for a single U21 campaign. Compatriot Jan Kliment won the adidas Golden Boot at the 2015 final tournament on home soil thanks to a hat-trick in the group stage.
Germany were the only team to pick up maximum points, winning ten out of ten in Group 7 to accumulate 30 points.
Germany scored 35 goals during qualifying, averaging 3.5 a game, more than any other side. Davie Selke top scored with seven while Leroy Sané, Max Meyer and Maximilian Arnold struck five apiece.
Only 36 players were involved in every minute – either 900 or 720 depending on whether it was a six or five-team group – of their country's qualifying campaign, including five members of Kazakhstan's side.
FYR Macedonia were ranked 40th (or 41st counting hosts Poland) when the qualifying draw was made. The only other UEFA final tournament the nation has reached was the 2010 WU19 EURO, when they qualified automatically as hosts.
Spain had 95 corners in total, 12 more than any other team. Some 26 came in one game, their 5-0 victory over Estonia.
There were 134 goals scored between the 31st minute and half-time, 18.9% of the total, making it comfortably the most prolific 15-minute period across qualifying. Next was minutes 61-75, when 123 goals – or 17.4% – were scored.
Denmark let in only three goals in ten games. They did not concede in the first 480 minutes of the campaign, until Gor Malakyan struck from the penalty spot for Armenia. Romania's George Miron, with his team already trailing 3-0 in Aalborg, looked set to be the only player to breach them from open play until the third minute of added time in the Danes' final qualifier, when Glenn Borges struck for Luxembourg.
Total number of goals scored throughout qualifying, at an average of 2.83 per game.
