Using data from the China 2001 national family planning and reproductive health survey provided by State Population and Family Planning Committee and 0 95 per thousand random sample data from the 2000 census of China provided by State Statistic Bureau, the current study depicted variations in sex ratios at birth (SRB) over time, across regions and for various other characteristics. The results showed that SRBs in China were continually abnormal high, especially for second or higher order births, and extremely high SRBs occurred to the births who had only elder sisters. These abnormally high SRBs became more and more serious over time, and the situation was the most serious in east China region and south China region; and in south China region, even SRB of firstborn children was abnormally high in 2000. There were quantitative data suggesting the induced abortions partly result in the abnormal high SRB in China.
