I had a discussion with someone on a different sub and I was curious about this question. I was having a hard time finding data. Many of the websites claiming it is not were pretty biased and didn't have much data one way or the other. What does the data say? How has immigration shaped America?
Hey, this is a great question, but I'd really suggest reshaping it to discuss a specific time period. Sticky speaking, immigration entirely shaped US culture considering that everyone here (except Native Ameicans) immigrated here at some point. This also complicates matters because immigration policies of the 17th century are drastically different then those in the 20th century. What exactly are you hoping to uncover? Do you want to know about why people immigrated here at different times. Do you want to know how these immigrants were relieved? What role they played politically or socially? Narrowing this down will help people on here provide clear answers
There are moments when immigration is super central for American history. If your refined question focuses on the nineteenth or early twentieth centuries, let me know!
