"Although both male and female births are underreported, the birth of a girl is twice as likely to be ignored. Underreporting is believed to account for about half to two thirds of the difference in infant sex ratios, which by the early 1990s had risen to 114 boys for every 100 girls. Unrecorded daughters may be left with relatives, adopted out, or abandoned to orphanages,13 which are increasingly unable to cope with the influx. Sex ratios are further skewed by widespread abortion, after the illegal but lucrative use of ultrasound to identify fetal sex."
