During 2012, 92% of abortions were performed before 14 weeks' gestation, 6% between 14–20 weeks, and 2% (n=96) at a later stage. Of the 96 abortions carried out beyond 20 weeks, 53 were due to actual or probable foetal abnormality.[11] Canada: During the year 2009, 29% of induced abortions were performed before 8 weeks, 41% at 9 to 12 weeks, 7% at 13 to 16 weeks and 2% over 21 weeks.[12] England and Wales: In 2005, 9% of abortions occurred between 13 and 19 weeks, while 1% occurred at or over 20 weeks.[13] New Zealand: In 2003, 2.03% of induced abortions were done between weeks 16 and 19, and 0.56% were done over 20 weeks.[14] Norway: In 2005, 2.28% of induced abortions were performed between 13 and 16 weeks, 1.24% of abortions between 17 and 20 weeks, and 0.20% over 21 weeks.[15] Between February 15, 2010 and December 1, 2011, a total number of ten abortions were performed between 22 to 24 weeks. These have been declared illegal by The Norwegian Directorate of Health.[16] Scotland: In 2005, 6.1% of abortions were done between 14 and 17 weeks, while 1.6% were performed over 18 weeks.[17] Sweden: In 2005, 5.6% of abortions were carried out between 12 and 17 weeks, and 0.8% at or greater than 18 weeks.[18] United States: In 2003, from data collected in those areas that sufficiently reported gestational age, it was found that 6.2% of abortions were conducted between 13 and 15 weeks, 4.2% between 16 and 20 weeks, and 1.4% at or after 21 weeks.[19] Because the Centers for Disease Control and Prevention's annual study on abortion statistics does not calculate the exact gestational age for abortions performed past the 20th week, there are no precise data for the number of abortions performed after viability.[19] In 1997, the Guttmacher Institute estimated the number of abortions in the U.S. past 24 weeks to be 0.08%, or approximately 1,032 per year.[20]
