Many jewelry store websites have charts showing the ideal bracelet length for every age range. Since the recommended bracelet length for a 12-year-old is 6.75", the average wrist circumference of a 12-year-old is likely to be 5-6 inches.There seems to be a rumor floating around the internet that 12-year-olds have 5cm wrists. This is either a measurement of something other than wrist circumference (most likely diameter), or the person who came up with that figure has never looked at a tape measure.

Head circumference of 3 year old?
Bra size is more a function of breast size and chest circumference than age.
Most 21 year old's chests won't be quite fully developed yet (it's the last part of the adult male to grow completely) so around 90-100cm (36-40 inches). For older males it'll be the upper limit of those measurements.
Head circumference is related to body weight. As the normal weight varies widely HC can also vary. The two should correspond on a centile chart. To answer the question... Average is roughly 16 inches or 40 cm (both numbers rounded to the nearest whole number.
