Respondents provided detailed information about contraceptive use and periods of stopping or switching methods during the past year. A typology of patterns of contraceptive use was created, classifying women into mutually exclusive categories according to their exposure to pregnancy risk.<\/jats:italic> <\/jats:p><jats:p><jats:bold>RESULTS:\u2002<\/jats:bold>  <jats:italic>Twenty\u2010three percent of women at risk of unintended pregnancy were exposed to a high risk of pregnancy because of gaps in contraceptive method use in the year prior to the survey\u20148% were consistent nonusers, and 15% experienced 1\u201311 months of nonuse while at risk. More than half of women used a method during each of the previous 12 months\u201438% used the same method or methods all year, and 24% switched methods. Fifteen percent of women had gaps in contraceptive use when they were not at risk.
