Overcrowded Beach, China

The policy is resisted, particularly in rural areas, because of the need for agricultural labour and a traditional preference for boys (who can later serve as male heirs). Families who breach the policy often lie during the census. Official government policy opposes forced sterilization or abortion, but allegations of coercion continue as local officials, who are faced with penalties for failing to curb population growth, may resort to forced abortion or sterilization, or manipulation of census figures.
The decreasing reliability of PRC population statistics since family planning began in the late 1970s has made evaluating the effectiveness of the policy difficult. Estimates by Chinese demographers of the average number of children for a Chinese woman vary from 1.5 to 2.0. The government is particularly concerned with the large imbalance in the sex ratio at birth, apparently the result of a combination of traditional preference for boys and family planning pressure, which led to the ban of using ultrasound devices for the purpose of preventing sex-selective abortion.
