Well every asian nationality has people with natural double eyelids and people with monolids. But I think some asian nationalities have more people with natural double lids. It seems like east asians have more people with monolids, while more southeast asians have more double lids. Idk why that is, but i've noticed it.
For me I know a bunch of Thai people with natural double-eyelids. I am actually one of them lol XD My mom, aunt, my whole family basically has double eyelids. My cousin's is strange, lol she has one monolid and one double eyelid, it's just so weird. She's partially chinese, her grandmother is chinese. So like 25% idk

I noticed them mainly on Vietnamese people.

i think... I THINK its more to skin colour than nationality..
u see.. ppl who naturally have darker skin colour most likely have a double eyelids. *like viets, filipino, etc222
while ppl who have fairer skin usually have single eyelids such as chinese, etc222
but if course, there's exception to everything.
since everyone in the world now is most likely mixed with God knows what
im fair, i look chinese, but i have HUGE eyes with perfect double eyelids.
so yeah.. but im mix with LOTS and LOTS of races, but my nationality is indonesian XD
Malay variety. Tawny-coloured; hair black, soft, curly, thick and plentiful; head moderately narrowed; forehead slightly swelling; nose full, rather wide, as it were diffuse, end thick; mouth large. upper jaw somewhat prominent with the parts of the face when seen in profile, sufficiently prominent and distinct from each other. This last variety includes the islanders of the Pacific Ocean, together with the inhabitants of the Marianne, the Philippine, the Molucca and the Sunda Islands, and of the Malayan peninsula. I wish to call it the Malay, because the majority of the men of this variety, especially those who inhabit the Indian islands close to the Malacca peninsula, as well as the Sandwich, the Society, and the Friendly Islanders, and also the Malambi of Madagascar down to the inhabitants of Easter Island, use the Malay idiom. -wikipedia

In addition to Asians and eastern subarctic and arctic Eurasians, some native American peoples (especially those of Middle America and some populations in South American lowland areas), the Capoid local race of southern Africa, and some of the composite racial groups of Pacific island peoples have high incidence of developed epicanthic folds. The fold occurs less frequently in Southeast Asian populations and in North American Indian groups but occurs occasionally in some European groups, for example in some Scandinavians and Poles.
While epicanthic folds occur more frequently in Asiatic groups and those peoples genetically linked to Asia, its presence is not universal in these peoples and it occurs less frequently in other groups. The incidence of epicanthic folds varies widely among the nine major geographic races and their local races. Attempts to define racial groups by the presence or absence of such features, by phenotype, rather than by genotype and specific inherited traits, are historically problematic and scientifically unreliable. There is substantial variation in phenotype within geographic races and subraces produced by the gene flow inevitable in an aggressively mobile species such as our own, by environmental conditions, and simply by individual variation due to a number of causes, including genetic mutation and the ‘small-sample’ effects of isolated population groups. Modern genetics rejects the notion of a ‘pure’ race; while the historical origins of some geographic groups are obscure, contemporary racial groups are mixtures of the gene pools of many geographic races. Thus, the presence or absence of a developed epicanthic fold, while an indication of one of a number of genetic origins and an important diagnostic feature of certain genetic disorders, cannot bear the cultural freight often bequeathed to it by history, pseudo-science, and prejudice.
The association of the epicanthic fold with Mongolians and Asians more generally served to reinforce notions of racial and cultural supremacy in nineteenth and early-to-mid twentieth century European physical anthropology, physiognomy, and racial theory. Humans with the genetic anomaly now known as Down's syndrome, caused by having three copies (trisomy) of chromosome 21, have limited physical growth and mental retardation of varying severity, and an increased risk of other serious physical problems. Down's syndrome is one of the more common chromosomal defects, occurring on average in 1 in 900 live births. The Down's syndrome infant is quickly recognized by both facial and more general cranial characteristics, including a rounded head, short neck, thin and usually fine hair, flat nose, small mouth, and, especially, slanting eyes with pronounced epicanthic folds.

Epicanthal folds refer to the folded skin of the upper eyelids which covers the upper inner corner, known as the canthus of the eye. It stretches from the nasal corner of the eye to the inferior side of the eyebrow. Eyes with epicanthal folds look almond shaped or boat shaped. Along with East Asian people, epicanthal folds are common in children with inherited genetic diseases. It may occur to fetuses or new born children of any race before the nose bridge starts elevating. Epicanthal folds can be fully developed or less developed and may change shape or decrease in size with age.
Epicanthal Folds Causes
The cause of epicanthal folds in East Asian people is still in doubt and there are various theories that hold genes, complex anatomy and the environment responsible for this. For other races, the causes of epicanthus folds can be associated with various genetic disorders.
Apart from congenital disorders, there is no other apparent cause found for epicanthal folds in people from other races than East Asian. In East Asian people, epicanthal folds neither pose any danger nor is the result of any disorder. According to the evolution theory, it may be a necessary variation in human genetics and adaptive feature that helps people adjust with natural local conditions. For example, epicanthal folds are common in people living in snowy regions, desserts, etc. Such eye design helps them protect themselves from strong winds, cold weather, and harsh UV rays. However, why the epicanthal fold trait exists is still unknown by medical science.
