人口再生产一、人口再生产类型的判断方法四种人口再生产类型的特点和差别教材已有论述,这是判断人口再生产的基本依据。如人口出生率和死亡率总体上呈下降趋势,原始型和传统型的人口出生率都在3.0%以上,但传统型的死亡率和自然增长率相对降低。据此,可区分这两种人口再生产类型;过渡型和现代型的出生率和死亡率都较低,但过渡型的自然增长率远高于现代型,据此,可区分这两种人口再生产类型;而传统型和过渡型的最主要区别是死亡率的差异,传统型死亡率一般接近2.0%,过渡型则一般不足1.0%。
Population Reproduction 1. Judgment Method of Population Reproduction Types The characteristics and differences of the four types of population reproduction have been discussed. This is the basic basis for judging population reproduction. For example, the birth rate and death rate of the population as a whole showed a downward trend. The birth rate of the primitive and traditional populations was above 3.0%, but the traditional mortality rate and natural growth rate were relatively lower. Based on this, the two types of population reproduction can be distinguished; transitional and modern birth rates and death rates are low, but the transitional natural rate of growth is much higher than the modern type, according to which two types of population reproduction can be distinguished. The difference between the traditional and the transitional type is the difference in mortality. The traditional mortality rate is generally close to 2.0%, while the transitional type is generally less than 1.0%.
