Abstract
Selection intensity, as indicated by total pre‐reproductive mortality and fertility (Crow, 1958), was computed among three Indian tribal populations living in similar geographical environments—the Kolams, Raj Gonds, and Pardhans of Adilabad District, Andhra Pradesh. The Pardhans showed the greatest selection intensity, (1.1811) followed by the Kolams (0.8564) and Raj Gonds (0.7240). Pre‐reproductive mortality and infertility contributed equally to selection intensity in these tribal groups.
