Empirical studies about the relationship between immigration and crime are mixed. Some studies have shown that immigrants do not particularly appear in criminal statistics.
American men (indigenous inhabitants) aged 18 to 39 years, five times more chances to be prisoners than immigrants at the same age. In a study published by a non -partisan group of the California Public Policy Institute, it was said that immigrants have ten times less likelihood of imprisonment than the natives of America. In his book in 1999, the sociologist of Tony Waters writes about the crime of young repatriates that the immigrants themselves have less likely to go to prison, but he noted that children of some immigrant groups are more likely to be in prison. This is a by-product of the strains that arise between the parents-immigrants living in the poor areas of the city. According to the judicial statistics bureau, for example, starting in 2001, 4% of the Spanish -speaking men in the twenties and thirties were in prison. Latin American men have almost four times more chances to get to prison than non-Latin American white men, although less likely than non-inflammatory Afro-American men. New immigrants are prone to create gangs, due to the influence of language barriers, difficulties in employment, lack of support, protection and fear. That is why life in Germany is considered safer in Germany, and it is difficult not to draw an analogy with the more rigid rules of immigration with them than in the United States.
Legal immigrants are checked for crime before adoption. Legal and illegal immigrants who commit serious crimes deport. Immigrants understand the serious consequences of the arrest, taking into account their legal status (for example, the threat of deportation).
