2002年人口变动情况抽样调查资料说明：本次调查登记的标准时间为2002年11月1日零时；调查样本设计以地域（层）为原则，采用了分层、三阶段、整群、不等概率比例的抽样方法，在全市18个区县中，抽取了98个街（乡、镇）级行政单位的219个居委会和106个村委会中的1.7万户，共调查登记了53740人，占全市常住人口总数的0.53%。由于在抽样设计上采用了不等比例的分配方法，因此，在进行计算机数据汇总时，按一定的比例进行了加权处理。加之在运算过程中因四舍五入的因素，有个别汇总表的分组数据（仅在尾数上）略有出入，相加可能不等于总计，但其比率不受影响。以下表2—10至2—14为这次调查机器汇总数据。
