But a University of Kansas researcher is a co-author of a study that has found those numbers are likely overblown and that a large number of those girls aren't missing at all — it was more of an administrative story that had to do with how births are registered at local levels in China.
The 2010 Chinese census found the sex ratio at birth was 118 males for every 100 females. Globally the average is about 105 males to females. In 2015, Chinese state media announced all couples would be allowed to have two children, signaling the end of the controversial 35-year-old policy, but scholars and policymakers are examining how the ban could have lasting social influence in China on everything from elderly care to political stability.
Kennedy and co-author Shi Yaojiang, of Shaanxi Normal University in China, have analyzed statistics and found that a combination of late registration and unreported births explains a larger portion of the "missing girls" than previously reported in Chinese sex-ratio-at-birth statistics. Their findings are published this month in the journal China Quarterly.
The researchers believe local government officials informally worked with farmers and acknowledged that they couldn't fully enforce the one-child policy. Instead they made tacit agreements in allowing families to have extra children in exchange for social stability in their communities. The cadres, or local governments, would then under-report “out of plan” births that ultimately influenced the national population statistics.
"We noticed that qualitatively when we interviewed villagers and higher- and lower-level officials everybody had a tacit understanding that yes, millions of girls and some boys, too, were allowed to be unregistered, and then these children appear in the population statistics as older cohorts at junior high school age and marriage age," said Kennedy, whose research focuses on social policy and change in China.
To supplement the qualitative data, the researchers then examined Chinese population data by cohort, and they compared the number of children born in 1990 with the number of 20-year-old Chinese men and women in 2010. In that cohort, they discovered 4 million additional people, and of those there were approximately 1 million more women than men.
"If we go over a course of 25 years, it's possible there are about 25 million women in the statistics that weren't there at birth," Kennedy said.
This could mean that instead of men outnumbering women by 33 million, the imbalance would be more like 8 million.
Under-reported births at the local level seem to explain why the marriage squeeze may not be as pronounced as previous scholars suggest.
Otherwise, their study provides more insight into how local villages and cadres operated. Diplomatically people have likely viewed the Chinese negatively, thinking villagers would be willing to kill their daughters to comply with the law, but Kennedy said this explanation about under-reported births would make more sense.
