A recent article in the Independent reported evidence that the sex ratio at birth is significantly male-biased within some ethnic groups in the U.K. The natural sex ratio at birth is approximately 105 boys to 100 girls. However, according to the article, there are groups in which the sex ratio at birth is as high as 1.2 for second born children. As the article points out, such large deviations from the natural sex ratio implicate the use of sex-selective abortions. In particular, parents who already have a daughter may be selectively aborting female fetuses in an attempt to ensure that their next child is a boy.
