in the United States
• The typical American woman wants two children. To achieve this goal, she must use contraceptives for roughly three decades.
• Virtually all American women aged 15–44 who are sexually experienced have at some point used a contraceptive method other than natural family planning (99%). This is also true of Catholic women, 98% of whom have used a contraceptive method other than natural family planning. 
• Modern contraception is highly effective. Among American women at risk for unintended pregnancy, the 68% who use a contraceptive method consistently and correctly account for only 5% of unintended pregnancies. The 18% who use a method inconsistently—for example, those who miss taking some pills or do not use a condom every time they have sex—account for 41% of all unintended pregnancies. And the 14% who do not practice contraception over the course of a given year, or who have long gaps in use, account for 52% of all unintended pregnancies. 
• The most effective methods for preventing pregnancy are implants, vasectomy, tubal sterilization and IUDs (all more than 99% effective); injectables (94%); vaginal rings, patches and pills (all 91%); diaphragms (88%); and male condoms (82%).
• Among American women who use contraceptives, the largest proportions use the pill (28%), tubal sterilization (27%) and the condom (16%). However, sterilization is the most common method among black and Hispanic women, while white women most commonly choose the pill. 
• In 2012, some 12% of women using contraceptives relied on long-acting reversible methods (the implant and the IUD). In 2009, this proportion was 9% and in 2002 this proportion was 2%.
• Most women who use the pill do so to prevent pregnancy; however, more than half also identify noncontraceptive health benefits, such as treatment for excessive menstrual bleeding, menstrual pain and acne, as reasons for use.
