Description:
In China in recent years, male live births have exceeded those of females by amounts far greater than those that occur naturally in human populations, a trend with significant demographic consequences. The resulting imbalance in the first-marriage market is estimated to be about 1 million males per year after 2010. These "excess" males were not easily accommodated in models with substantial changes in first-marriage patterns. The current sex ratio at birth has little effect on a couple's probability of having at least one son, so future increases in the sex ratio may well occur, especially given increasing access to sex-selective abortion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tuljapurkar, S -- Li, N -- Feldman, M W -- HD-16640/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1995 Feb 10;267(5199):874-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Morrison Institute for Population and Resource Studies, Department of Bioloical Sciences, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7846529" target="_blank"〉PubMed〈/a〉
