“A concentration camp is a prison or other facility used for the internment of political prisoners or politically targeted demographics, such as members of national or ethnic minority groups, on the grounds of national security, or for exploitation or punishment.”

Do we know what is happening to these people? What their conditions are? Why do we not hear from them afterwards?

It's an important topic and it's worth getting the terms correct. Concentration camps and extermination camps are two different things. Not that Jewish and other peoples were not killed in concentration camps, either by being worked to death or by summary execution, but they were not the almost assembly line killing factories of the extermination camps.

This is a term that is also used (in an American context) to refer to the sites where Japanese-Americans were imprisoned during WWII.

That's an extermination camp. Concentration camps are just for segregating and isolating people from society. Like what US did to Japanese in the past.

And it has nothing to do with Jews.

> A concentration camp is a place where large amounts of Jews were killed. U

That's incorrect. A concentration camp is a place where a government or authority detains large numbers of people without normal legal process, usually because they belong to a particular group rather than because of individual crimes.

Historical examples:

- Nazi Germany (1933–1945)

- British camps during the Second Boer War (1899–1902)

- Imperial Japan

- United States (1942–1945)

People can be concentrated without being killed.

Not so! Concentration camps predate the Nazis by quite a bit, and the term was/is used for all kinds of prison-like setups where inmates are held outside the rule of law.

E.g. US camps holding Japanese immigrants during WW2.

Sure, it might be somewhat hyperbolic (arguable, because ICE/current administration has few qualms dismissing constitutional rights whenever convenient), but the term is definitely not Nazi-exclusive (even the Germans had concentration camps long before Hitler, in Namibia)

You are talking about extermination center which is a subset of concentration camps. First concentration were open after Hitler took power and were always referred to as concentration camps by historical books. They were not used as extermination camps yet, the gas chambers were not invented yes. The first prisoners were political opposition, low level criminals and yes, jews. The frequent pattern with political prisoners was to imprison them for 1-3 months, break them and then release them to create terror.

Jews were removed from public life at first, over-punished for minor infractions and deported or pushed toward self deportation. The thing to notice here is that Germany did not had that many Jews in the first place, they were rather small minority. The tens of thousands thing was possible only after Germans conquered foreign lands and started to kill non German Jews. The WWIII did not started yet, so yep, we are not there, but it is actually OK to comment on similarities before that.

There were concentration camps before and after the Holocaust (not to mention millions on non-Jewish people were murdered on the camps you allude to).

Also, tens of people have already died in those concentration/detention camps.
