This is not the correct way to do this analysis.
Feel free to provide a better analysis and explain why your analysis is better.
Boot, this is just basic statistics. It doesn't make sense at all to look for any kind of "correlation" across a gigantic population sample, particularly when you could just look at the effect on crime rates when migrants move in to a community.
Let's look at one: Hazleton, PA.
In 2000, the Hispanic population was less than 5%; in 2010, the Hispanic population was over 37%, and by 2020 was 63%. (Source: U.S. Census.) I am using the Hispanic population as a proxy for migration; there are plenty of other sources indicating this was primarily due to immigration.
The overall population was relatively stable (around 25k-27k total).
In 2000, the FBI's reported violent crime rate was below 150. By 2018 it was over 450.
This is in sharp contrast to your reported overall drop in crime rates from 2000 to 2020.
Thanks for providing a concrete example. I appreciate that—it’s always helpful to ground things in real places and stories.
That said, from a basic statistics perspective, larger sample sizes and broader trends are usually better for seeing the big picture. That’s what I was aiming for earlier. Hazleton may have seen crime rise alongside immigration, but dozens of other cities (like El Paso, San Diego, and Miami) saw major immigrant population growth while crime fell. And there are cities where crime rose without a corresponding increase in immigration—like Portland, New Orleans, or Albuquerque. So I’m not sure a single example tells us more than the national trend.
From 1990 to 2020, the foreign-born share of the U.S. population doubled. During the same period, violent crime dropped by more than half. That doesn’t prove immigrants reduce crime, but it does challenge the idea that they cause it.
Whatever the causes are, violent crime really has gone down. At the same time, a lot of people feel like it’s going up. That gap between perception and reality seems important to me. A lot of people seem to feel like we’re in an emergency state, with unprecedented levels of violent crime—but the data just doesn’t show that.
I think it’s worth asking why we feel more afraid, even when things are getting statistically safer. That might tell us just as much about our society as the crime data itself.
1. Are we discussing the topic? Good.
2. Are we going around and around in a fight? Let's stop doing that.
3. Is there some serious wrongdoing or relational injury? Let's address that, probably not in public and certainly not for show.
