The study of contraceptive use is crucial for several reasons: 1. Reducing Unintended Pregnancies: Understanding the prevalence and types of contraceptives used can help reduce unintended pregnancies, which are associated with adverse maternal and child health outcomes. 2. Public Health Planning: Data on contraceptive use informs public health strategies and resource allocation. 3. Sexual Health: Contraceptives play a key role in preventing sexually transmitted infections (STIs).
