Numerical and Graphical Results of Germany Population Projection Using WASD Neuronet

Abstract

Population issues are critical to national development, social stability and resource allocation. Policy-makers hope to Figure out population factors such as birth rate, size, and demographic structure to make policies that are conducive to longterm development of a country. Therefore, population projection has always been highly valued by many government workers and scholars. Compared with other traditional population projection methods, the weights and structure determination (WASD) neuronet does not require a vast knowledge of demography to achieve excellent performance. In this work, we substantiate the WASD neuronet by numerical experiments, which show the excellent performance of the WASD neuronet. Then, we make short-term and mid-term projections of Germany population and also make comparisons with other mainstream population projection methods. Finally, this paper presents a reasonable tendency of Germany population, i.e., declining slightly in near future but growing gently in one decade.
