About the Presentation

This study examines the impact of the presence of siblings on individuals’ sexual behaviors throughout adolescence and young adulthood. I find that the presence of siblings of all varieties – brothers and sisters that are older and younger – are associated with later timing to sexual initiation and lower accumulation of sexual partners throughout young adulthood; however, these influences extend only to girls and not boys (with a few exceptions). I also find that, for girls, the presence of older sisters reduces the likelihood of contraceptive use at sexual initiation. The findings imply that the presence of siblings provides a mix of potentially ‘protective’ and ‘non-protective’ influences on individual sexual behaviors that are gendered and long lasting.
