the 184 cm could be including some non whites.The average dutch student weight on average around 180 lbs lean and 184.8 cm.
http://dined.io.tudelft.nl/nl,dined2004,301 ( in dutch).right their is calculater 1 SD( standard derrivation) and said 26.6% above 190 cm which is close to your 20%.
less then 160 lbs or 200 lbs plus( lean no gym) are often seen too. Dutch record shot put is 21.62 still further then arab or east asian.
But we are I think to small country for a lot of WR and a lot of events not populair, but enough for better result then best result of then evry east asian( decathlon, shot put, discuss, 1500 meter ,1600 meter, 800 meter and more) but it would be better if we could do sports like in america with school like i already said.
but we are at least always top 10 or close to top top 10( like top15 or so) in the oympic games.
all the old WR's in swimming of dutch Innge de bruin, pieter van den hoogenband and team-swimming are broken in the time with the new swimming suits (were aloud for a year or so).of the dutch young generation is 25% non white, they are around 35% in the amateur leagues and a little less then the pro leagues( 25%).the minoritys nearly all play soccer or do a fight sport.the fight sport accomodations are mostly in the big citys and are over 90% participated by non whites.But some whites dutch world champion mostly when it is not only punching wirh arms but also with legs muay thai, Sem schilt 4 times k-1, Peter Aerts 3 times k-1, Bas Rutten american fight sport or so. were mostly what would be considered nordic, with some alpine and meditteranic elements, espacially under the rhine river- which can also be called the Roman river lol.within the nordics you had differnt tribes too, the strongest bodied being the borreby germanic 20% elementt here mostly north east isolated , i remember that i saw jaap stam teamfoto from before hew went to pro he was with 200 lbs the the skinniest of the soccer team and they are often natural and not juiced, fat like american football players.Around Kampen and north of that are a lot of white beasts.
