The nature and value of censuses.

PIP: In both developed and developing countries it is necessary and desirable for governments to enumerate their resources and essential characteristics, and to chart change and growth in their populations. These functions, and more, are served by the census. To properly fulfill this function, it is most important that the census relate to a single point in time and cover a clearly defined territory. On a practical level, a timely compilation of the statistics is also necessary for the greatest benefit to be derived from them. The basic resources necessary for its speedy completion should be assured. In general these encompass capital, manpower, and machines. A census may also profitably make use of government records and documents already available at all levels of administration. The quality, reliability, and accuracy of the statistical information should not be taken for granted. Governments would do well to include in their programs an evaluation of the statistics resulting from the census. This could serve as a guide in determining the best interpretation and most suitable use of these statistics.^ieng
