Hungary performed a new census in the redeemed territory in December 1938. The census took place in an atmosphere of expulsions, persecutions, restriction of civil rights and psychological coercion of Hungarian authorities. In addition, it was performed under direct control of military bodies and violated several principles for taking a census of nationalities. According to the results, the population consisted of 86.5% Hungarians and 9.8% Slovaks. The total size of Slovak population was reduced to 121,603, 67 villages lost Slovak majority the size of the Slovak population was decreased by 74,100 and the Hungarian population increased by 77,715. Contrary to the Czechoslovak census of 1930, the Hungarian census again counted not the nationality declared by citizens but the "mother tongue" registered by census commissars, as in the Hungarian census from 1910. The two censuses significantly differed in the view on Jewish population. In Czechoslovakia, Jews were allowed to declare separate Jewish nationality, but in the Hungarian census, they missed own mother tongue, and their real numbers can be estimated only by their declared religion.
