The reporting of children's ages by parents is surprisingly inaccurate in many innumerate societies, but accurate knowledge of age is important for estimating recent changes in demographic rates. The timing of the eruption of children's teeth is largely independent of environmental influences and can provide a relatively accurate and unbiased estimate of a child's age. We have collected published data from 42 studies of children's dentition and have transformed them into estimates of age for children with particular numbers of teeth. We present estimates for different populations, but the lack of significant differences between these estimates justifies the use of a standard set.
在许多缺乏数字概念的社会中,父母对孩子年龄的报告惊人地不准确,但准确了解年龄对于估算人口统计率的近期变化很重要。儿童牙齿萌出的时间在很大程度上不受环境影响,并且可以提供相对准确且无偏差的儿童年龄估计。我们收集了42项关于儿童牙列研究的已发表数据,并将其转化为具有特定牙齿数量儿童的年龄估计。我们给出了不同人群的估计值,但这些估计值之间缺乏显著差异,这证明使用一套标准是合理的。
