In September 1983, we selected 30 villages in four rural counties of northern Haiti for a partial census and malaria prevalence survey. A cohort of 1,577 persons was enumerated in this census. Survey teams revisited the same houses in these villages in September 1984 and updated the previous census, inquiring about all listed family members. We administered an additional questionnaire to each household concerning the occurrence over the past year of deaths, births, pregnancies, and migration. Among the 1,218 persons who had been followed for one year, there were 21 deaths (crude mortality rate: 17 per 1,000 population; 95% confidence interval [95% CI]: 12 per 1,000, 25 per 1,000) and 35 births (birth rate: 29 per 1,000 population year; 95% CI: 19 per 1,000, 38 per 1,000). The infant mortality rate was 171 per 1,000 live births (95% CI: 81 per 1,000, 315 per 1,000), and the mortality rate for children less than 5 years old was 36 per 1,000 (95% CI: 24 per 1,000, 56 per 1,000). Although small sample surveys are subject to limitations of precision dependent on sample size, they can be a simple method by which researchers may estimate vital statistics for rural areas of less-developed countries.
1983年9月，我们在海地北部四个乡村县选取了30个村庄进行部分人口普查和疟疾患病率调查。此次人口普查共登记了1577人。1984年9月，调查小组再次走访了这些村庄的相同住户，更新了之前的人口普查信息，询问了所有登记家庭成员的情况。我们还向每户发放了一份额外问卷，询问过去一年中家庭成员的死亡、出生、怀孕和迁移情况。在1218名被随访一年的人员中，有21人死亡（粗死亡率：每1000人中有17人死亡；95%置信区间[95%CI]：每1000人中有12人至25人死亡），35人出生（出生率：每1000人年中有29人出生；95%CI：每1000人中有19人至38人出生）。婴儿死亡率为每1000例活产中有171例（95%CI：每1000例中有81例至315例），5岁以下儿童死亡率为每1000人中有36人（95%CI：每1000人中有24人至56人）。尽管小样本调查受限于样本量导致的精度问题，但它们可以是研究人员估算欠发达国家农村地区生命统计数据的一种简单方法。
