Abstract:The reproductive histories of 74 post-menarcheal Agta Negrito women, tropical foragers of Cagayan province, north-eastern Luzon, the Philippines are described and analysed in comparison with data collected by Howell on Dobe! Kung hunter-gatherers. Among the Agta, mean age at menarche is 17, mean age at first live birth is 20·14 years, mean completed parity is 6·53 and mean age at menopause is 44. Average height is 141·24cm and average weight 36·72 kg. No time trends were detected in age at menarche and age at first live birth among the Agta. Average spacing between live births where an infant survives until the birth of the next sibling was 2·85 years. Compared to the Dobe !Kung, Agta women have later menarche, but shorter birth spacing and a longer active childbearing span.
