[Marvel] What do we know about Latveria? What languages do its people speak? What are some of its ethnic groups? Are Latverian Slavs, Magyars, Romanian, Roma or a little bit of all?

Latverian, related to or potentially a dialect of Hungarian, is the primary language of Latveria, though German and Romany are also common.  The majority of the population is a unique mixture of Hungarian and Balkan Slavic ethnicities.  There is also a significant Romani minority.  This group was formerly persecuted by the government but as Dr. Doom is Romani the persecution was ended by him when he assumed power.  Interestingly enough despite his villainous nature for the most part the non-Romani Latverians haven't suffered reprisals for the past treatment of the Roma.  Latverian society is egalitarian as long as everyone accepts that Doom is superior.   

Population and land wise Latervia is small, it likely has less than 1 million people and is likely the smallest nation in the Balkans/Southeast Europe Region.  

Despite this Latveria is one of the world super-powers, equal to the US, Wakanda, and China.  This is entirely because of Dr. Doom's technological prowess.  The nation has a large number of robotic soldiers that individual can equal a battalion of other nations.  And between his suit and magical abilities Dr. Doom by himself has more military power than 95% of nations on Earth.  The actual human military forces of Latveria are relatively small, even as a percentage of the nations population.  And most of these are likely ceremonial postings.  Latveria also has the Latverian School of Science that has several meta-human students that could be used in the nations defense.  These include a half-demon/half-human hybrid.

Economically, Latveria is reliant on Doom.  Before, his rise to power Latveria was relatively poor, with timber as the main export.  Since, his rise to power Dr. Doom has begun selling his outdated technology to other nations.  This tech still vastly superior to most other technology available is in high demand.  This exported technology is now the vast majority of Latveria's GDP.

Society and politics have become centered around Doom.  Previously, the culture was similar to the surrounding nations.  But, now Doom is the center of all Latveria culture with holidays and celebrations being in his honor.  Due to the new found prosperity and ever-watchful eye of Doom, Latveria is relatively peaceful and crime free.  However, there are those that bristle on Dr. Doom's authoritarian regime.  Resistance to Doom's rule is not allowed, and can result in execution.  Though that being said most Latverians support Doom, he brought an end to ethnic tensions, increased the standard of living, and has made Latveria strong enough to resist outside encroachment.

Diplomatically, Latveria is considered both a rogue state and superpower.  Most of the developed world distrust Latveria (or more specifically its ruler), but antagonizing Latveria is rarely worth it.  Even, if Doom doesn't overtly take action against a hostile nation he is willing to supply weapons and tech to its enemies.  There are other nations that are fond of Latveria, as a counter-balance to the US, Latveria can be a natural ally against US influence.  Latveria can also be a ally to Eastern European nations wanting protection from Russia, though this would merely be moving oneself from a Russian to Latverian sphere of influence.  It hasn't been explored much but China and Latveria would both benefit from close ties.  Neither of their interests generally conflict, and both have similar rivals.

**Edit* Forgot to mention education.  Education in Latveria is prioritized and mandatory.  It also seems to be free.  Given his nature, history and political science courses are likely heavily propagandized in favor of Doom.  However, math, science and art seem to be encouraged.  Latverian science course seem to be among the best in the world.
