Sixteen million girls are missing in China. And now we know what happened to them: They were aborted because they weren't boys.
A study published last week in the British Medical Journal, based on a survey of nearly 5 million Chinese children and teenagers, bares the gruesome numbers. Worldwide, the number of boys born per 100 girls ranges from 103 to 107. (The numbers later equalize due to higher male mortality.) Among Chinese children born from 1985 to 1989, the number of boys per 100 girls was 108, close to normal. But among those born from 2000 to 2004, the number rose to 124. The authors conclude that as of 2005, "males under the age of 20 exceeded females by more than 32 million."
Why so many more boys than girls? The authors point to two factors. First,
[T]he steady rise in sex ratios across the birth cohorts since 1986 mirrors the increasing availability of ultrasonography over that period. The first ultrasound machines were used in the early 1980s; they reached county hospitals by the late 1980s and then rural townships by the mid-1990s. Since then, ultrasonography has been very cheap and available even to the rural poor.
Second, the boy-girl ratio escalates radically among children who were born second or third in their respective families. The authors report:
The sex ratio at birth for first order births was slightly high in cities and towns but was within normal limits in rural areas. However, the ratio rose very steeply for second and higher order births in cities 138 (132 to 144), towns 137 (131 to 143), and rural areas 146 (143 to 149), although the numbers of second order births in cities were low. These rises were consistent across all provinces, except Tibet, with very high figures for second births in Anhui (190, 176 to 205) and Jiangsu (192, 174 to 212). For third births, the sex ratio rose to over 200 in four provinces …
Two hundred boys for every 100 girls. The number is mind-boggling.
