　　出生率
　　birth rate
　　　　每 1000人口的全年活产婴儿数。其公式为：□/□×1000‰。式中□为全年活产婴儿数,不论妊娠期长短，婴儿脱离母体时，有呼吸、心跳、脐带搏动、肯定的随意肌收缩等生命现象者称为活产。 □为全年总人口活过的人年数，即平均人数，常以年中人口数替代。出生率受人口的年龄、性别构成的影响，只能大致反映一地的生育水平，所以亦称粗出生率或总出生率。
　　　　计算出生率时，应保持分子、分母内涵的一致性。若按常住人口计算总人口时，出生人数应按婴母的常住地进行统计。按常住地统计出生率能避免妇女离开常住地生育给当地生育水平带来的影响。若按出生地统计出生人口，那末以现有人口数作分母更合理。
　　　　为细致观察年内出生率变动，可计算月出生率。如某地1988年4月出生婴儿数为□□，则月出生率为
　　　　 □分母为1988年4月当地平均人口数,所以月出生率的算式为
　　　　 □相邻年份的同月出生率对比，可反映一年内生育水平的变化。按同样原则，可计算年初到报告月的累计出生率，按某类人口计算的出生率称特殊出生率，如城镇和农村的出生率、各民族的出生率、不同行业和不同职业人口的出生率等。
