The number of male per 100 female live births (defined as the sex ratio at birth, SRB) has been shown to be consistently stable in human populations irrespective of time and geographical location. All over the globe approximately 105 boys are born for every 100 girls and any significant deviation from this 'global average' is considered to be unnatural and is attributed to sex-selective under-reporting of births, sex-selective abortion, sex-selective infanticide or other man-made factors. The present paper uses data on civil registration from 2004-2011 to investigate the sex ratio at birth in modern Greece. It was found that the SRB is extremely masculine when the parents originate from the Indian sub-continent and China. The SRB is also unnaturally high (more than 113 boys per 100 girls) in the case of legitimate births born to Greek mothers who are illiterate. These findings are strong evidence that sex-selective abortions are taking place in Greece within population groups with a certain ethnic and social profile. Other parameters, such as age of mother at birth, birth order, legal status of birth and geographical location, were also investigated and they were found to play a role in the variation of SRB, but not to the extent education and ethnic group do.
每100例女性活产对应的男性数量（定义为出生性别比，SRB）在人类群体中一直保持稳定，不受时间和地理位置的影响。在全球范围内，每出生100名女孩，大约会有105名男孩出生，任何与这个“全球平均水平”的显著偏差都被认为是不自然的，并且归因于出生性别选择性漏报、性别选择性堕胎、性别选择性杀婴或其他人为因素。本文利用2004年至2011年的民事登记数据，对现代希腊的出生性别比进行了调查。研究发现，当父母来自印度次大陆和中国时，出生性别比极具男性偏向性。对于希腊文盲母亲所生的合法婴儿，出生性别比也异常高（每100名女孩中有超过113名男孩）。这些发现有力地证明了希腊特定种族和社会背景的人群中存在性别选择性堕胎现象。研究还调查了其他参数，如母亲生育时的年龄、胎次、出生的法律地位和地理位置，发现它们在出生性别比的变化中也起到了一定作用，但程度不及教育程度和种族群体。
