人口自然增长率的计算公式是:人口自然增长率=出生率-死亡率出生率=(年内出生数)/(年平均人口数)×1000(‰)死亡率=(年内死亡数)/(年平均人口数)×1000(‰)
The formula for calculating the natural population growth rate is: Natural population growth rate = Birth rate - Death rate Birth rate = (Number of births during the year) / (Yearly average population) × 1000 (‰) Death rate = (Number of deaths during the year) / (Yearly average population Number) × 1000 (‰)
