A link between increased immigration and increased crime?
While researching the cause of the apparent (as Shonk noted, it may be an artifact of bad stats) spike in the homicide rate in the early 1900s, the tremendous immigration of that first decade popped out as a possible cause. I googled to find out what has been said about that, and discovered papers like this .
