Historical demographics[edit]
According to the researchers the town had a German majority until the mid-16th century. The Ottoman Turkish traveller Evliya Çelebi mentioned that the city was inhabited by "Hungarians, Germans, Upper Hungarians" in 1661 when the city was under the suzerainty of the Ottoman Empire and under Turkish control. But by 1850, the Slovaks gained a plurality of 46.5%, with Hungarians reduced to 28.5% and Germans at 15.6%.
The linguistic makeup of the town's population underwent historical changes that alternated between the growth of the ratio of those who claimed Hungarian and those who claimed Slovak as their language. With a population of 28,884 in 1891, just under half (49.9%) of the inhabitants of Košice declared Hungarian, then the official language, as their main means of communication, 33.6% Slovak, and 13.5% German; 72.2% were Roman Catholics, 11.4% Jews, 7.3% Lutherans, 6.7% Greek Catholics, and 4.3% Calvinists. The results of that census are questioned by some historians by claims that they were manipulated, to increase the percentage of the Magyars during a period of Magyarization.
By the 1910 census, which is sometimes accused of being manipulated by the ruling Hungarian bureaucracy, 75.4% of the 44,211 inhabitants claimed Hungarian, 14.8% Slovak, 7.2% German and 1.8% Polish. The Jews were split among other groups by the 1910 census, as only the most frequently-used language, not ethnicity, was registered. The population around 1910 was multidenominational and multiethnic, and the differences in the level of education mirror the stratification of society. The town's linguistic balance began to shift towards Slovak after World War I by Slovakization in the newly established Czechoslovakia.[citation needed]

According to the 1930 census, the city had a population of 70,111, with 230 Gypsies (today Roma), 42,245 Czechoslovaks (today Czechs and Slovaks), 11,504 Hungarians, 3,354 Germans, 44 Poles, 14 Romanians, 801 Ruthenians, 27 Serbocroatians (today Serbs and Croatians), and 5,733 Jews.
As a consequence of the First and Second Vienna Awards, Košice was ceded to Hungary. Starting on 15 May 1944, during the German occupation of Hungary towards the end of World War II, approximately 10,000 Jews were deported by the Nazis, with the enthusiastic assistance of the Hungarian Interior Ministry and its gendarmerie (the csendőrség). The last transport to Auschwitz left the city on 2 June, three months before the Arrow Cross Party gained control over Hungary. The ethnic makeup of the town was dramatically changed by the persecution of the town's large Hungarian majority, population exchanges between Hungary and Slovakia and Slovakization and by mass migration of Slovaks into newly built communist-block-microdistricts, also known as paneláks, which increased the population of Košice four times by 1989 and made it the fastest growing city in Czechoslovakia.
