Just in case you need Korematsu maps of the United States, that is where immigrant populations are located, take a look at: Maps of the Foreign Born in the US.
For those of you unfamiliar with the Korematsu case, it involved the mass detention of people of Japanese ancestry during WW II. With no showing that any of the detainees were dangerous, disloyal, etc.
The thinking at the time and when the Supreme Court heard the case after the end of WW II, was that the fears of the many, out weighed the rights of the few.
You may be called upon to create maps to assist in mass detentions by race, ethnic or religious backgrounds. Just wanted you to know what to call them.
