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

I. THE COMPREHENSIVE REWIEV OF THE DATA COLLECTION AND PROCESSING - 1. The prepatory activities of the census

As far as the data referring the housing situation are concerned, the house-rent has been omitted from the Hungarian census of the year 1970, since the respective data are available in the regular statistical survey materials. Questions put as to the lift and the garage figuring among the complementary questions of the United Nations, are not included to the Hungarian programme of housing statistics. c/ EXPERIMENTAL REGISTRATION PRIOR TO THE CENSUS Experimental registration and the micro-census of 1968 The theoretical moment of the micro-census (serving at the same time to experimental purst poses) was fixed for the 1 January 1968. It aimed at testing for the scope, the questionaries, the methods of data collection and the electronic data processing as well as at the fixing of the programme. Since the micro-census - according to the techniques of the sample survey to be outlined in the following - was not based on the registration of full districts, but of flats selected, it Was unable to test for the regional organization, the designing of the census districts and the listing techniques. Consequently, separate smaller registrations also became needful. Inasmuch a fuller knowledge of methodology applied in performing the micro-census is wanta/ ed, we refer to the publication expounding the results. ' The sample survey techniques of the micro-census connected with the experimental registrast tion held on the 1 January 1968 was essentially identical with the methodology applied on the occasion of the micro-census of 1963. A two-per cent sample was applied in both cases, namely a two/ stage stratified sample. In the first stage communities, in the second dwellings have been selected. As to the sample design, the selection of the communities was motivated by the concentration of the registration work to smaller areas and thus by the simplification of the local organization and activity. In the second stage, the including of the dwellings to the sample was motivated by the fact that dwellings (buildings) dispose of a steady, permanent character, while households and inhabitants are changing and moving. The probability of the communities to get included to the sample was - similarly to the techniques applied in 1963 - proportional to their size; consequently, in the second stage, it became possible to select the same number of dwellings within each community. That meant an equal charge for the census-takers.In the communities having less than thousand inhabitants, 18-18 dwellings while in communities over thousand inhabitants 36-36 dwellings have been selected for the sample (the respective figures were 15 and 30 dwellings in 1963). Communities and towns having more than 5 000 inhabitants have been included without any th exception. In such cases, the registration concerned, by means of mechanical selection, every 50 dwelling. The stratification of the communities has taken place according to their size (number of inhabitants) and further, within the communities having more than thousand inhabitants, according to the occupational characteristics of the inhabitants. a/ Personal, household and housing data of the micro-census of 1968.
