For the statistician responsible for conducting a household sample survey its purpose includes the specification of the population or universe to be investigated, the parameters or the population values (e.g. averages, frequency distributions,. totals) to be estimated and the specification of the necessary precision of the estimates of the parameters. For example, it should be known in advance whether the survey is a nationwide investigation of households or a regional one, or, if nationwide, whether separate estimates are needed for certain areas or certain sections of the population. In addition, it is necessary to indicate at the outset what material should be collected in the survey from the units selected, what characteristics should be studied and what parameters or population values should be estimated from measurements made on the units selected. It is also very important to keep in mind the immediate uses that will be made of the survey results since such immediate uses, to a large extent, dictate the precision with which estimates are needed.
