Although much research has been devoted to understanding differences in contraceptive behaviour among socieconomic groups of married women, little is known about group differences among young unmarried women. In this paper, data from a national survey of women 15–19 years of age are used to study the relationship between socioeconomic status, sexual activity, and contraceptive use. The socioeconomic status of the young women is related to age at first intercourse, contraceptive use at first intercourse, regularity of use, and use of medical methods. The results indicate that both an earlier initiation of sexual activity and less regular use of contraceptives in all probability lead to a concentration of pregnancies in the lower socioeconomic groups.
