The 2018 FIFA World Cup is the 21st international football tournament of its kind.
 Both tournaments were awarded in a single bidding process on three occasions, with the U-20 tournament serving as a dress rehearsal for the larger competition each time (2010, 2014 and 2018)
 They are held within the six FIFA continental zones (Africa, Asia, North and Central America and Caribbean, South America, Oceania, and Europe), overseen by their respective confederations
