a misunderstanding i see often is people thinking “20% of the population is quirkless” must mean 1 in 5 children born is quirkless

that is not what it means

20% of the population is quirkless

current population 

a good chunk of that population is going to be elders, when quirklessness was more common

and then a smaller amount (but still a good chunk) is going to be middle-aged. but at this point its more likely that most quirkless people are single or have no children or their children passed on their other parents quirk assuming they had one

either way the percentage in quirkless people in young adults is really low

the percentage in teenagers would be less than 5%

the percentage in current toddlers would be 1-2%

20% of the population =/= 1 in 5 babies being quirkless

quirklessness is rapidly decreasing, it is now extremely rare

that 20% is probably even lower, considering that massive stigma against the quirkless

“20% of hte population is quirkless” factoid is a ctually a statistical error. the average person has a quirk. quirkless georg, the boomers of the world and are mostly quirkless, are outliers and should not be counted
