Long Term Efficacy of Different Birth Control Methods

In September 2014, the New York Times presented charts pertaining to the effectiveness for each type of birth control over a ten year period. Definitions for “typical use” and “perfect use” are above the charts and the differences between them are seen in applicable charts. (Please note that by “perfect use” it means how the method is ideally to be used every single time…and as humans, we are naturally infallible). As you can see, Tier 1 birth control methods (Intrauterine Devices, Nexplanon implant and sterilization) are far more effective over any time period compared to Tier 2 (injections, pills, patch, ring), Tier 3 (condoms, diaphragm and fertility awareness methods) and Tier 4 (withdrawal and spermicides) birth control methods.
