40m bachelors and no women ... the birth of a new problem for China  

1.  China, the most populous nation on Earth, could find itself dealing with the combined frustrations of as many as 40 million single men by 2020 because its one-child policy is creating a shortage of female babies.

2.  Even in urban areas, boys are generally preferred because they are regarded as more able than girls to provide for their families, care for elderly relatives and continue the family line.

3.  Several years ago the government prohibited doctors from telling couples the sex of their child, but the measure seems to have had little effect.
