After Man the Hunter, conventional wisdom was that hunter-gatherer bands consist of about twenty-five persons and live at population densities that are only 20–30 percent of the environment's carrying capacity. Many argued that hunter-gatherers intentionally hold their populations in check through high rates of infanticide, especially female infanticide, and consequently experience low rates of population growth. We only have population-growth-rate measures for the Ju/’hoansi (0.5 percent; Lee 1979; Howell 1979), the Agta (1.1 percent; Early and Headland 1998); the Ache (2.5 percent; range: 1.6–3.5 percent; Hill and Hurtado 1996); the Hadza (1.4 percent; Blurton Jones, Smith, O’Connell, Hawkes, and Kamuzora 1992); and the New Guinean Asmat (1.5 percent; Van Arsdale 1978). From their analysis of foraging group sizes, Hamilton et al. (2007a) suggested a mean growth rate of 1.1 percent.
