"Illegal immigrants cause crime"[edit]
- Whilst a common cry of the anti-immigration brigade — "backed" by a font of endless anecdotal "evidence" — the facts don't support this. According to FBI statistics in Arizona in 2008, despite the increased presence of illegal immigrants, crime rates have actually dropped, while the population has increased.[28] Only 8% of the prison population are immigrants, which also includes legal immigrants as well.[29]
- Furthermore, El Paso, Tex., and San Diego, Calif., cities that border Mexico and have a significant population of undocumented immigrants, have the lowest crime rates in the U.S.[30]
- "...between 1990 and 2013, as the foreign-born share of the United States population nearly doubled and the number of unauthorized immigrants more than tripled, violent crime declined 48 percent and property crime fell 41 percent."[31]
- Illegal immigrants are less likely to commit crimes against US citizens than other US citizens are.[32][note 2]
- If you mean crime against illegal immigrants (which happens), that is "caused" by them only in the sense that it would be impossible if they didn't exist.
