BEVEZETŐ

INTRODUCTION The Hungarian Central Statistical Office, in its series of publications containing the 1990 population census data, publishes also collections of data which ensure comparability with the respective data of former population censuses though the latter data - however interesting might have been completely or partially missing from earlier publications. This time the group of data relating to national groups - mother tongue, national group-belonging, religion - is published in county rows. For the interpretation of the data of the present publication the following remarks on methodology and, respectively, the concepts used must be taken into consideration: - the Hungarian population censuses are based on self-reporting. The legal rules ordering the population censuses have always called up the population to report truthful data and the instructions for the enumerators have always stressed the importance to register answers supplied free from all influences, especially with regard to national group-belonging and mother tongue; - until 1970 and from 1980 on, the data refer to the population present and to the resident population, respectively; - county rows of previous censuses are published according to the administrative division figuring in the original publications of the respective censuses. Each county data row is followed by those of towns with special legal status in the respective county (free royal boroughs, municipal boroughs, county status towns etc.); - detailing, succession and denomination of data correspond to those figuring in the original census publications. Relating to the given topic, two further publications are to be taken into account, of which the first one - a volume containing time-series on mother tongue, nationality and knowledge of languages, transformed according to the country area and administrative division as of January 1, 1990 - has already been published. In 1980, the data relating to national group-belonging and mother tongue by localities were not published, so the other volume planned presenting the data on national group-belonging and mother tongue of 1980 and 1990 will fill the gap. 4
