The significant imbalance in the sex of children at birth is believed to be primarily caused by the availability of abortions and the population's preference for one of the sexes of the unborn child. For example, the "one family - one child" policy, which was in effect in China from 1979 to 2015, is believed to have led to mass deliberate abortions if the child was a girl.
True, from this point of view, Liechtenstein's long-standing world leadership in this indicator is unclear, because abortions are prohibited in this country. This can be partly explained by the fact that Liechtenstein has a small population in principle, and therefore statistics are subject to the strong influence of certain random factors. However, there is no widespread explanation for the "Liechtenstein phenomenon" yet.

Below are the countries where the male to female ratio is 1.1 or higher:
The Gulf states' leadership is explained by immigration - these states recruit male workers who cannot bring their wives with them. In many of these states, the immigrant population far exceeds the native population.
Interestingly, the gender ratio in China is not as bad as is commonly believed: the current male predominance ratio is 1.038, compared to 1.065 in India.
