 The population of larger towns like Košice or Bratislava were historically bilingual or trilingual, and some might declare the most-popular or the most-beneficial nationality at a particular time.According to the Czechoslovak censuses, 15–20% of the population in Košice was Hungarian, but during the parliamentary elections, the "ethnic" Hungarian parties received 35–45% of the total votes (excluding those Hungarians who voted for the Communists or the Social Democrats).However, such comparisons are not fully reliable, because "ethnic" Hungarian parties did not necessarily present themselves to Slovak population as "ethnic", and also had Slovak subsidiaries.
