You are clearly reading the data incorrectly. It says that immigration (third world or not) reduces the crime and murder rate. U.S.-born citizens are more prone to incarceration.

You're including unrelated immigrants to wash your data. The question is on third world immigrants ONLY.

Otherwise you can say things like guns don't have bullets because we looked at "things that kill" and most of them don't.

That's obviously not a good way to answer questions.

Try talking with an expert or get help from someone to understand why we don't use statistics like that to make business or medical decisions.

I hope you have an easy time figuring it out.

Good luck.

> According to the study, this is the case for almost every region in the world that is a major source of immigrants to the United States.

Nice, except "almost" doesn't describe anything relevant to the question and its inherent subjectivity makes it useless especially when attempting to draw from a pool of data that's not relevant to the question.

"Almost everyone in the US is white," doesn't tell you anything about the demographics of the US. It's still technically true, but it's painting a grossly inaccurate picture of the demographics.

You should take on some statistics lectures or macrobio on Khan or something. This isn't a good platform for in depth discussion. You're not going to learn anything from this.

Talk to an expert. When they see what you're doing they will easily explain what's wrong to you.

Although, maybe these examples I gave are enough.
