china has warned its people that unless families start having more girl babies , "army" of 70 million bachelors will be roaming the countryside looking for wives by the end of the century. the proportion of males to females is already out of balance since 51.45 percent of china's 1.1 billion people are men. with the percentage increasing in the younger age groups. the ratio of male births to female births is now 114 to 100,and among the 25 to 49 age group,there are 15 times more unmarried men than unmarried women.Analysts say the problem may stem from china's strict birth control policies,which limit most families to only one child.
