Population experts have estimated that the imbalance over the past 30 years has resulted in between 24 million to 34 million more men than women.
Wang Pei’an, vice-minister of the National Health and Family Planning Commission, has warned that the gender imbalance could result in serious social problems, state-run China Daily reported.
A national guideline released this month said the authorities will continue to intensify the fight against foetus gender identification and sex-selective abortions.
Wednesday’s outline estimated that China will see its population peak at 1.45 billion around 2030.
To better monitor demographic changes, China plans to establish a population forecast system based on censuses and sample surveys that will produce regular reports, the outline said.
