*Request - can someone actually present some evidence on the usage of "illegal immigrants" vs "undocumented migrants" in the sources rather than using Wikipedia as a forum for their personal opinions? I don't care what you think or feel. I want to know how the phenomenon is described in recent reliable sources, so that we can follow Wikipedia policy. My sense of it is that the term "illegal immigrants" used to be predominant but in recent years "undocumented migrants" has become much more widely used. I don't know if the extent of that switch has been substantial enough to warrant moving this page. But I want to see evidence about it, not opinions.
