I. THE COMPREHENSIVE REWIEV OF THE DATA COLLECTION AND PROCESSING - 6. Sampling techniques applied in the census

The main results are tabulated in two schedules. The first reflects the nation-wide figures, the second shows the data concerning Budapest and two other characteristic counties. According to the computation results as shown in the annexed Tables, the confidence limits of the district sample are considerably higher than those of a sample of the same size based on individual selection. In the maximal case, the standard error amounts to the threefold value of the error obtained in the case of the individual sample selected by simple random sampling. As compared to the 1 per cent individual sample, however, - as well as compared to the 1 or 2 per cent sample of the flats - the confidence intervals of the district sample of 25 per cent representativity are considerably lower in the case of all criteria examined, even with the most doubtful occupational criteria.
