*The relative effectiveness of a birth control method is defined in two ways: actual effectiveness and theoretical effectiveness. Actual effectiveness refers to the "typical use" of a method, meaning how effective the method is during actual use (including inconsistent and incorrect use). Theoretical effectiveness refers to the "perfect use" of a method, which is defined by when the method is used correctly and consistently as directed.
