2004年10月，按照我国第一次全国经济普查的要求，湖北省某市某镇进行全镇经济普查，66岁的农民杨振龙当上了某村的普查员，他第一次上报的该村个体经营户营业收入是63万多元，全镇初步汇总个体经营户营业收入是8000多万元，与前几年上报的“约10亿元”差别太大。镇领导认为“经济普查数要考虑去年年报数和今年目标数”，要求普查员们重新填表，并将“约10亿元”的数字分解到20多个村，还明确要求：如果落实不到人，就虚拟到人。老杨领到的任务是“6820万元”，是实际数字的107倍。于是他用了一个上午的时间编姓名编项目，伪造了25份普查表报出了7000余万元的荒唐数字。通过这样明目张胆的造假，该镇个体经营户营业收入总额达10.09亿元。
