information, however, research must be considered. This means that data need to be collected from an appropriate source. If a potential source of data exists, managers will want to know how much it will cost to get the data. If the data cannot be obtained, or it cannot be obtained in a timely fashion, this particu lar research project should not be conducted. For example, many African nations have never conducted a population census.
