چکیده
1. Before proceeding to a projection, it is necessary to examine the definitions according to which data on "urban" and "rural" population have been determined. Under some definitions, for instance, "urban" areas remain within constant geographic boundaries, and "urban" population, so defined, can grow by births, deaths and migration only. According to some other definitions, the geographic extent of "urban" areas can expand continuously; in such a case, the "urban" population grows by area reclassifications as well as by births, deaths and migration.
