The Casiguran Agta constitute a Negrito hunter-gatherer society in northeastern Luzon. The hypothesis presented is that this population has suffered serious decline over the last half -century. Demographic data collected over a 24-year period are used to substantiate this hypothesis. Agta figures on crude death rate, rate of natural decrease, infant mortality, life expectancy at birth, and homicide are among the most extreme known for any human population. Reasons for this decline are described, with emphasis on the factor of homicide.
卡西古兰阿格塔人是吕宋岛东北部的一个尼格利陀狩猎采集社会。提出的假设是，在过去半个世纪里，这个群体的数量严重减少。利用24年期间收集的人口统计数据来证实这一假设。阿格塔人的粗死亡率、自然减少率、婴儿死亡率、出生时预期寿命和杀人率在已知的任何人类群体中都是最为极端的。文中描述了人口减少的原因，重点是杀人这一因素。
