重男轻女在许多文化和社会中已经存在了几个世纪。在包括中国和印度在内的一些亚洲国家，出生性别比（SRB，男婴数除以女婴数乘以100）高于约105的世界生物学标准。我们调查了美国移民女性的这一比例是否升高。我们分析了2004-2013年美国的出生证明，并根据母亲和父亲的种族/民族对出生进行了分类；母亲的出生地，孩子的出生顺序。在两组女性中，性别比升高：在中国出生的出生顺序为2及以上的中国女性，以及在印度出生的出生顺序为3及以上的印度女性。在美国出生的中国和印度女性，墨西哥女性、黑人女性和白人女性，无论出生地点如何，SRB都没有升高。孩子父亲的种族/民族似乎不是SRB的一个重要因素。在21世纪初，分别在中国和印度出生的中国和印度女性的高SRB表明，在美国，性别选择更高级
Son preference has existed for centuries in many cultures and societies. In some Asian countries, including China and India, the sex ratio at birth (SRB, number of male infants divided by number of female infants times 100) is elevated above the worldwide biological norm of about 105. We investigate whether this ratio is elevated in the U.S. for immigrant women. We analyze U.S. birth certificates for 2004-2013 and categorize births by mother's and father's race/ethnicity; mother's place of birth, and birth order of the child. The SRB is elevated for two groups of women: Chinese women born in China for children of birth order 2 and higher, and Indian women born in India for children of birth order 3 and higher. The SRB is not elevated for Chinese and Indian women born in the U.S., nor for Mexican women, Black women, nor White women, regardless of place of birth. The race/ethnicity of the child's father does not appear to be a strong factor in the SRB. In the early twenty-first century the elevated SRB for Chinese and Indian women born in China and India respectively suggests sex selection for higher order births in the U.S.
