Most cultures? I don't know if that is still the case. The global 'westernized' culture has spread quite a bit. I have lived in a couple of Asian countries, in cities. There were soft versions of arranged marries-- soft where the marrying couple could turn it down-- going on in the background there, and maybe in the villages. In Indonesia, a maid who went to my church who had come to faith in Christ faced pressure from her father who was trying to match her up with a Muslim man in the village. Young women from my wife's father's village who went to college could match up with boyfriends they met through dating there, and they started arranging marriages if they got a little up in years, though I heard my wife's cousin was kind of set up. My wife was surprised because she was pretty, and could find a man. The woman died relatively young, too a few years back.
I don't know who would count, but it is possible most people-groups still have some arranged marriage customs that are in practice while the majority of the world may generally match up through more modern dating practices. Many people-groups have small numbers, and larger people-groups may live more in the cities where dating is more common.
Dating can also be different from how it is in the US. In South Korea, going on a blind date with the third wheel who is matching you up is common. I got set up on one once without realizing it.
Is arranged marriage common among this people group? It's interesting that that survived.
I met a couple who are probably in their 50's, maybe late 50's. They both migrated to the US from Cuba. The man's parents mentioned a girl they wanted to set him up with. I don't think it was exactly an arranged marriage. Maybe it was. But the man went to a party and met this young woman who had just arrived from Cuba, and he really hit it off with. They ended up shaking up together. It turned out it was the same girl his parents wanted to match him up with. But the parents were upset that they had moved in together. Neither of them were believers, and Communist atheism had damaged the sexual morals of Cuba also. But they both eventually became Christians.
Why don't you go down to Brazil, attend church, and let a girl catch you? If she's pretty and sweet, you could run really, really slow.
