Demographic information was collected on a fortnightly basis between 1974 and 1978 in the framework of the Machakos Project. Results reported here deal with population size and increase on a de jure and de facto basis, population composition by age and sex, and crude birth and death rates. The results show that the study area is characterized by somewhat lower fertility than the national average of Kenya and much lower mortality. In addition, there is net-in-migration into the study area and the overall result is very rapid population increase. It is argued that underreporting of births and deaths, has been kept to a minimum due to the design that was used together with the use of several control measures.
在马查科斯项目的框架下，于1974年至1978年期间每两周收集一次人口统计信息。此处报告的结果涉及法定和实际人口规模及增长情况、按年龄和性别划分的人口构成以及粗出生率和死亡率。结果表明，研究区域的生育率略低于肯尼亚全国平均水平，而死亡率则低得多。此外，有净移民进入研究区域，总体结果是人口增长非常迅速。有人认为，由于所采用的设计以及多项控制措施的使用，出生和死亡的漏报情况已降至最低。
