摘要
研究全国人口普查问题模型,旨在为政府统计部门核实人口数量和统计人口结构提供重要参考,以做出科学决策。研究对象是人口普查标准时点上的人口总体数量。利用这些数据推理、计算出最大人口数和人口增长率,得到人口普查问题模型。通过数理论推理数理逻辑,用MATLAB进行模型实验,实际数据与预测数据拟合,进行误差微调。经过实验证验并可以对人口数量预测,进行人口结构预测,为政府决策提供数据支撑。
The purpose of studying the national population census model is to provide important references for the government statistics department to verify the population number and statistical population structure so as to make scientific decisions. The research object is the total population at the standard time point of the census. By reasoning these data, the maximum population and the population growth rate are calculated, and the population census model is obtained. The model experiment is carried out by using MATLAB through mathematical theory and mathematical logic. The actual data is fitted with the predicted data, and the error is fine tuned. After experimental verification, it can predict the population number and the population structure, and provide data support for government decision-making.
