1970 HUNGARIAN CENSUS OF POPULATION Information on the data collection and processing (1977)

I. THE COMPREHENSIVE REWIEV OF THE DATA COLLECTION AND PROCESSING - 4. Notions applied with the population census

persons living together should be meant who live in a common dwelling or in a part of it, having a common meal at least once a week and commonly bear the costs of living On account of the modified family concept and the prevalence of the household as observation unit, the primary unit of the data processing work was in the census of 1970 the household to which the notion of the family was but exceptionally annexed. This practice diverged from that followed in 1960, when the consideration of the family was general and the household was used as complementary notion only. • e/METHODOLOGICAL CHANGES OCCURED IN THE HOUSING AND BUILDING STATISTICS As compared with the former census, the programme of the registration and data processing concerning the dwellings has been considerably enlarged in 1970. At the same time, the methodology of the registration and the data processing also underwent changes in the case of buildings and dwelling houses, i.e. the data processed and published have been limited only to the analysis of the most important criteria. A part of the questions referring the dwelling situation and usually put on the occasion of the former censuses became included to the programme of the registration of the dwellings (as for instance the character of property, the year of construction, means of sewage etc. ) The survey method itself has been modified. Instead of using separate questionaries to both topics, the data referring to the dwellings and the building - as closely connected notions - have been collected by means of a common sheet in 19 70. In doing so, not only the number of questionaries used by the staff could be reduced, but an opportunity offered itself for the combination of the criteria during the data processing, by means of making use of the advantages of the computer technique. Thus several criteria applied in the survey programme of the dwellings, could also be used at the same time for characterization purposes of the buildings, as for instance the equipment. A new item of the data collection was the observation of the "half-rooms" - a method ensuring the working out the figures of the living accomodation needful'to the purposes of housing programmes and policy. The further changes which occurred in the field of the dwellings and buildings are as follows: Occupied dwelling The overwhelming part of the information concerning the inhabitants was connected with the notion of the socalled "resident population" in 1970, while formerly the "present population" was the category most frequently us-ed in the previous censuses. Complying with this, the definition of the "occupied dwelling" has also been changed. A dwelling is considered occupied if one person at least resides in it at the census moment, on the basis of a permanent or temporary police registration form. 34
