Forecast: Sex ratio to balance out by 2030

China's sex ratio at birth will keep falling and eventually reach a balance within 15 years due to economic and social development and the relaxed family planning policy, the central government has predicted.

The ratio, which was 113.5 men to every 100 women in 2015, one of the highest in the world, is forecast to drop below 112 by 2020 and 107 by 2030, according to the National Population Development Outline released Wednesday by the State Council.

The normal range is between 103 and 107.
