People asked why the wait for children from China is so long, why there are less children. Here is one answer from: http://chinaadoptiontalk.blogspot.com/2010/07/amy-eldridge-of-lwb-speaks.html
Why the significant change? First, she said, there has been a growth in more modern attitudes about girls. It is really only in the rural areas that the social preference for boys remains. Ten years ago, 85% of the Chinese population lived in rural areas. Now, only 50% are rural, 50% urban. With that urbanization has come more education, the internet, and the like, which has led to more modern attitudes. Second, there has been growth in the availability of ultrasound technology. Now, anyone who is pregnant can know the child's sex. Anyone who carries a girl to term does so knowingly and with every intention of parenting her. Those who want a boy instead will have an abortion. Third, domestic adoption in China is growing rapidly. That's caused in part by the public interest in adoption after all the news reporting about the orphans of the Sichuan earthquake. And another factor is the increased rate of infertility in China. One government agency estimates that as many as 40 million couples in China are infertile. Infertility is skyrocketing because of increased premarital sex without much sex education, causing increased rates of STDs and frequent abortions that might be less than sterile and because of environmental toxins and pollution. Domestic adoption is preferred by orphanage directors, because domestic adopters pay higher fees than international adopters. In Guangzhou, domestic adopters pay fees of $15,000 to the orphanage; in Hefei, the fee is $7,000 for domestic adopters. Most adoptions are handled on the county or provincial level, even though the CCAA now has a national office of domestic adoption. Orphanages just don't send the files of healthy infants for international adoption when they can place the child domestically.
The idea that there are less children because there are so many more abortions is really sad.
