ABSTRACT

The population of the world attracts considerable attention, as it is closely related to the development of human society. The prediction of the world population, which can be used for planning and research, is becoming more and more important. The population problem has been one of the major problems that influences and restricts the development of human society. The population studies based just on fertility, mortality and other individual factors may lead to the lack of all-sidedness in the prediction results that differ sharply from the actual population of the world. In addition, the population studies based just on the data may miss the consideration of sudden disasters that may happen in the future, thereby making the prediction results of the world population world population less comprehensive. The historical population data contain the general regularity of the population development, and are also the comprehensive reflection of the population development under the influence of all factors.
