Generally poverty and crime are the two that correlate heavily and so in sectors of the population where you have high levels of poverty then you also have high levels of crime which is why safety nets and welfare are so important for reducing crime.

If you think about immigration that is a subset of the population that have high levels of poverty, low levels of access to welfare and so if things go wrong they get desperate quickly. And they also have more problems than locals at getting work due to discrimination and a host of other reasons.
