The main difference between the arguments of the two parties was that the Hungarians presented the 1910 census figures, as had Germany during the Munich Conference, but Czechoslovakia presented the latest 1930 figures and contested the validity of the 1910 census. Later, it also presented figures from Hungarian censuses before 1900. The census from 1910 was unacceptable for the Czechoslovak delegation because it represented the peak of Magyarization and differed from previous Hungarian and later Czechoslovak censuses as well as postwar censuses from other countries in which the Hungarian minority lived (Austria, Romania and Yugoslavia). Tiso gave an example, as he was also counted as a Hungarian during that census. At the same time, the Hungarian delegation did not accept the results of the Czechoslovak census, proposing to use the Hungarian census from 1880, before the peak of Magyarization, as a compromise. The Hungarians also did not agree on definition of "pure Hungarian" towns like Košice, as were understood by Hungarian delegates.
