Fertility in animals directly reflects access to scarce resources, such as food and territory. In humans, the situation is more complex. Patterns of breast feeding, contraception and ideas about age of marriage and desired family size all affect fertility. This book explores the relation among these factors and access to scarce resources, via income, education and other forms of status.
