The person performing the coding had but.to record a figure which showed to which household (if there are more than one) the person in question belonged, and within the household, to which family again (if the household consisted of a number of families). In addition to the above, the coding personnel defined the family status of the person registered, by recording the code numbers of the status held within the family and the household. The recording of the code consisting of five figures ensured the assembling of the household and the family compound to be shaped by the computer (Fig. no. 2. ) Similarly to the assembling of the file of the households and families, the compound of the file of buildings has been performed in the same manner.
