主要统计指标解释
常住人口数 指一定时点、一定地区范围内的有生命的个人的总和。年度统计的年末常住人口数指每年11月1日0时的人口数。
出生率(又称粗出生率) 指在一定时期内(通常为一年)平均每千人所出生的人数的比率，一般用千分率表示。计算公式为：
出生率＝(年出生人数／年平均人数)×1000‰
式中：出生人数指活产婴儿，即胎儿脱离母体时(不管怀孕月数)，有过呼吸或其他生命现象。年平均人数指年初、年底人口数的平均数，也可用年中人口数代替。
死亡率(又称粗死亡率) 指在一定时期内(通常为一年)一定地区的死亡人数与同期平均人数(或期中人数)之比，一般用千分率表示。计算公式为：
死亡率＝(年死亡人数／年平均人数)×1000‰
人口自然增长率 指在一定时期内(通常为一年)人口自然增加数(出生人数减死亡人数)与该时期内平均人数(或期中人数)之比，一般用千分率表示。计算公式为：
人口自然增长率＝[(本年出生人数－本年死亡人数)／年平均人数]×1000‰＝人口出生率－人口死亡率
就业人员 指年满16周岁，为取得报酬或经营利润，在调查周内从事了1小时（含1小时）以上劳动的人员；或由于在职学习、休假等原因在调查周内暂时未工作的人员；或由于停工、单位不景气等原因临时未工作的人员。
各单位的就业人员 指在各级国家机关、政党机关、社会团体及企业、事业单位中工作，取得工资或其他形式的劳动报酬的全部人员。包括在岗职工、再就业的离退休人员、民办教师以及在各单位中工作的外方人员和港澳台方人员、兼职人员、借用的外单位人员和第二职业者。不包括离开本单位仍保留劳动关系的职工。各单位的从业人员反映了各单位实际参加生产或工作的全部劳动力。
城镇登记失业人员 指有非农业户口，在一定的劳动年龄内，有劳动能力，无业而要求就业，并在当地就业服务机构进行求职登记的人员。
城镇登记失业率 指城镇登记失业人数同城镇从业人数与城镇登记失业人数之和的比。计算公式为：
城镇登记失业率=城镇登记失业人数／(城镇从业人数+城镇登记失业人数)×100%
国有单位职工 指在国有经济单位及其附属机构工作，并由其支付工资的各类人员。
城镇集体单位职工 指在城镇集体经济单位及其管理部门工作，并由其支付工资的各类人员。
其他单位职工 指在联营经济、股份制经济、外商投资经济、港、澳、台投资经济单位工作，并由其支付工资的各类人员。
在岗职工 指在本单位工作并由单位支付工资的人员，以及有工作岗位，但由于学习、病伤产假等原因暂未工作，仍由单位支付工资的人员。
平均工资 指企业、事业、机关单位的就业人员在一定时期内平均每人所得的货币工资额。它表明一定时期职工工资收入的高低程度，是反映就业人员工资水平的主要指标。计算公式为：
职工平均工资＝报告期实际支付的全部就业人员工资总额／报告期全部职工平均人数
Explanatory Notes on Main Statistical Indicators
Total Population refers to the total number of people alive at a certain point of time within a given area.The annual statistics on total population is taken at 0:00 on November lst .
Birth Rate( or Crude Birth Rate) refers to the ratio of the number of births to the average population during a certain period of time(usually a year) which is often expressed in ‰. The following formula is used:
Brith Rate= (Number of Births/Annual Average Number of Population)×1000‰
Number of births refers to live births i.e. the births when babies had showed any vital phenomena regardless of the length of pregnancy.
Annual average number of population is the average of the number of population at the beginning of the year and that at the end of the year. Sometimes it is substituted for with the mid year population.
Death Rate(or Crude Death Rate) refers to the ratio of the number of deaths to the average population (or mid year population) during a certain period of time (usually a year) which is often expressed in‰. The following formula is used:
Death Rate =(Number of Deaths/ Annual Average Number of Population)×1000‰
Natural Growth Rate of Population refers to the ratio of natural increase in population(number of births minus number of deaths)in a certain period of time(usually a year)to the average population(or mid year population)of the same period which is often expressed in‰. The following formula is applied:
Natural Growth Rate of Population= [(Number of Births-Number of Deaths )/ Average Number of Population]×1000‰
Natural Growth Rate of Population=Birth Rate-Death Rate
Employed Persons refer to persons, aged 16 and over, who performed some work for compensation or business gains for one hour or more during the reference period; or persons who do not work for the reasons of study or on holiday; or persons who are temporarily absent from a job for disorganization or suspension of work, recession, etc.
