Why don't North America have as many European whites and Indians as Latin America?

I think this problem should be related to many factors. The first immigrants to North America were usually British and French. They immigrate to find more places to live, so they usually get married and have children after arriving in North America. And they have firm religious beliefs and racial discrimination. They think white people are noble, so they generally don't marry other people!

Generally, people who go to Latin America are Spanish. They moved there because they found a lot of gold mines in Latin America. And their purpose is to dig gold and silver mines, and most of them moved here are men. So they will have families and children here, so there are many mixed-race descendants in Latin America.

Another reason is that because of the racial policy, the colonists who came to North America were very exclusive to the locals. They will also launch a series of armed wars against the local Indians. They will drive the Indians to the designated quarantine area and forbid their own people to contact them to get married. Spanish colonists going to Latin America will discriminate against Indians, but they will only treat them as slaves or bully them instead of isolating them. Instead, Indians were placed at the bottom of the social class, so there were few women in Latin America at that time, and the ratio of men to women was very uncoordinated, so when there was no way, they would marry Indians.

It may also be the natural environment, because the living environment of British and American colonists is very similar to that of North America, while the living environment of Spanish colonists is very different from here, so I think the survival of the fittest is also the same.
