undocumented immigration on homicide, aggravated assault, robbery, burglary and larceny crime rates.
Here's where those who would argue in favor of deporting ALL immigrants - documented or undocumented - would point out that there were no statistics on undocumented immigrants committing sexual assault, especially against children. That was one of the biggest rallying cries during both of the current president's election campaigns.
For example, we found in a 2017 study with colleagues that from 1970 to 2010 metropolitan areas with greater concentrations of immigrants, legal and undocumented combined, have less property crime than areas with fewer immigrants, on average. Critics suggested that our findings would not hold if we looked at only the subset of undocumented individuals.
From a purely scientific standpoint - and not just a racist xenophobic one - it's best to look at data from all viewpoints. In this case, it would be crime statistics from cities with greater concentrations of purely undocumented immigrants in one study, then in another, statistics from documented immigrants.Then, separate the statistics by race, ethnicity, gender, orientation, etc. - to see if their were any underlying causes for the crimes.
But undocumented immigrants, and immigrants more generally, are often baselessly blamed for increasing crime rates – including, repeatedly, by President Donald Trump. In the second and final presidential debate, Trump again claimed undocumented immigrants are rapists and murderers.
Why is this such a widespread belief? Is this another example of human's fear of the unknown being exploited for another human's personal gain?
