Global incidence The global rate of<unk>  was estimated at 44% of all<unk> es between 2010 and 2014, corresponding to approximately 62<unk> es per 1000 women between the ages of 15–44 years old. While<unk>  rates have been slowly downtrending in most areas of the world, different geographic regions have different estimated<unk>  rates. Rates tend to be higher in low-income regions in Latin America and Africa, estimated at 96 and 89<unk> es per 1000 women, respectively, and lower in higher income regions such as North American and Europe, estimated at 47 and 41<unk> es per 1000 women, respectively. Incidence by country/region Europe From 1990–1994 to 2010–2014, European rates of<unk>  decreased from approximately 66 such<unk> es per 1000 women ages 15–44 years old to 41. These rates vary between different European countries. Britain According to a 2013 study approximately 16% of British<unk> es are unplanned, 29% are ambivalent, and are 55% planned. France In France, 33% of<unk> es are<unk> . Of women at risk for<unk> , only 3% do not use contraception, and 20% use intrauterine devices (IUDs). Sweden One study from Sweden (2008-2010) showed that the prevalence of<unk> es was 23.2%. One study conducted in Uppsala (2012–2013) found that 12% of<unk> es were fairly or very unplanned. Russia According to a 2004 study, current<unk> es were termed "desired and timely" by 58% of respondents, while 23% described them as "desired, but untimely", and 19% said they were "undesired". North America From 1990-1994 to 2010-2014, North American rates of<unk>  decreased from approximately 50 such<unk> es per 1000 women ages 15–44 years old to 47. United States According to the Guttmacher Institute, slightly less than half (45%) of U.S.<unk> es in 2011 were<unk> , approximately 2.8 million<unk> es per year. In 2006, most states' rates were between 40 and 65<unk> es per 1,000 women. The state with the highest rate of<unk> es was Mississippi, 69 per 1,000 women, followed by California, Delaware, the District of Columbia, Hawaii and Nevada (66 to 67 per 1,000). New Hampshire had the lowest rate, 36 per 1,000 women, followed by Maine, North Dakota, Vermont and West Virginia (37 to 39 per 1,000 women). Over 92% of abortions are the result of<unk> , and<unk> es result in about 800,000 abortions/year. In 2001, 44% of<unk> es resulted in births, 42% resulted in induced abortion, and the rest in miscarriage. It is estimated that more than half of US women have had an<unk>  by age 45. According to one study, over one-third of living people in the US under 31 years of age (born since 1982) were the result of<unk> es, a rate that has remained largely unchanged to date. +<unk> es and births in the United States Rate per 1000 women.
