Sorry I am a little bit confused here. In order to get the actual average height of men between 20 to 30, an additional 2cm must be added to the average height collected from the data. So, say, the average height for Chinese nowadays is 175, then 177 is the average height of the youth. Am I correct? Because the data also collected the older generation, who are shorter.
You're lucky to see my last post about revealing Lancet's stupidity and imbecile concerning false data from quotations and estimations.
Also,lately Chinese Planning Commission of science and Research Fund has published a nearly 1cm growth but at best between 95s and 00s youngsters' average heights,but due to height measuring scrunity institute shortages and demographic volatilities,this growth was absolutely falsely exaggerated cuz there are no chances that 00s citizens are tremendously taller than 95s citizens(from analysis of data growth,such excellent growth was not contributed by solely villagers) and I think it's not necessary at all to explain this common sense.
I dare even reckon that,essentially,Lancet's mistake was a British-Iranian 'scholar''s weaved plot and ideologies & philosophies spread out from it are poisoning and devastating people especially with height dysphorias but these are all my reasoning so it's not entirely plausible and expensive.
Also,many indigenous scholars from other countries apart from the England were participating in this estimation so there are only chances that national average heights were only exggerated and filtered for ulterior motions.Some insanly tall countries couldn't dispatch scholars into the Lancet due to indigences so the average height rank of both males and females was fked up.
But I dunno if the immanent interventions bc of international competitions among all of overseas scholars had impacts on estimations so I guess that's why fking North Korea average height was fabricated as 174.7cm barefoot.
I guess Kim Jong-un dispatched a primary student to do the Maths in the Lancet medical group or just other North-Korea-friendly bastards commited the crime.
