According to the scientists, nearly 4,7 million fewer girls will be born around the world by 2030 due to sex-selective practices in countries with cultural preferences for male offspring, as AFP reported.
"To model what short- and long-term effect sex selection will have on societies, an international team of researchers analyzed data from more than three billion births over the last 50 years," the media says.
Scientists simulated two scenarios.
The first assumed an increase in the rate of sex selection, based on statistical evidence. In this scenario, countries saw a shortfall of 4.7 million in the number of girls being born by 2030.
The second scenario assumed increased sex selection in certain countries, based on observed trends and decreased fertility, but for which specific data were lacking. The figure jumped to more than 22 million globally by 2100 in this case.
It is stated that a decrease in the number of girls will lead to a surplus of young men by 2030. This can lead to increased levels of antisocial behavior and violence. In addition, it can affect the reduction in the number of marriages.
To note, sex-selective abortions have been on the rise for the past 40 years in countries throughout southeast Europe along with south and east Asia, with as-yet-undetermined demographic impacts.
