The territories of the former Hungarian Kingdom that were ceded by the treaty to neighbouring countries in total (and each of them separately) had a majority of non-Hungarian nationals, however the Hungarian ethnic area was much larger than the newly established territory of Hungary, therefore 30 percent of the ethnic Hungarians were under foreign authority.
After the treaty, the percentage and the absolute number of all Hungarian populations outside of Hungary decreased in the next decades (although, some of these populations also recorded temporary increase of the absolute population number). There are several reasons for this population decrease, some of which were spontaneous assimilation and certain state policies, like Slovakization, Romanianization, Serbianisation.[citation needed] Other important factors were the Hungarian migration from the neighbouring states to Hungary or to some western countries as well as decreased birth rate of Hungarian populations. According to the National Office for Refugees, the number of Hungarians who immigrated to Hungary from neighbouring countries was about 350,000 between 1918 and 1924.Minorities in post-Trianon Hungary
On the other hand, a considerable number of other nationalities remained within the frontiers of the independent Hungary:
According to the 1920 census 10.4% of the population spoke one of the minority languages as mother language:
551,212 German (6.9%)
141,882 Slovak (1.8%)
36,858 Croatian (0.5%)
23,760 Romanian (0.3%)
23,228 Bunjevac and Šokac (0.3%)
17,131 Serbian (0.2%)
7,000 Slovene (0.08%)
The percentage and the absolute number of all non-Hungarian nationalities decreased in the next decades, although the total population of the country increased. Bilingualism was also disappearing. The main reasons of this process were both spontaneous assimilation and the deliberate Magyarization policy of the state. Minorities made up 8% of the total population in 1930 and 7% in 1941 (on the post-Trianon territory).
After World War II approximately 200,000 Germans were deported to Germany, according to the decree of the Potsdam Conference. Under the forced exchange of population between Czechoslovakia and Hungary, approximately 73,000 Slovaks left Hungary and according to different estimations 120,500 or 45,000Hungarians moved to present day Hungarian territory from Czechoslovakia. After these population movements Hungary became an almost ethnically homogeneous country with the exception of the Hungarian speaking Romani people.
