Where have all the flowers gone?
To the Editor: The title of the recent editorial1 applies too to a related theme: gender imbalance.
The distinction between male and female is a key dimension of population dynamics.2 In some southern and eastern Asian countries, the sex ratio has become skewed towards men, partly in consequence of gender-selective abortions;3,4 in the People's Republic of China, for example, the newborn male/female ratio is about 119:100.4 Similar data have been observed in India3 and among immigrants to Europe from Asia.5 For traditional, economic and social reasons, many families prefer to have sons, and this is a cause of the increased male/female ratio, infanticide, abandonment of newborn girls, and neglect of daughters.6 The preponderance of males occurs predominantly in lower socio-economic classes, and there is concern that their marginalisation may lead to antisocial behaviour threatening societal stability and security.6 An excess of men conduces to insecurity, in turn motivating families to have more sons for protection. Son preference has been reported also from Africa,7 where gender shifts are not yet prominent, probably because of the unavailability of prenatal gender testing. However, should fertility decline, the motivation for gender-selective abortions would become stronger, and many families would try to have at least one boy to secure the patriarchal lineage.7
Population size and gender imbalance in some countries can be underestimated because men are predominant in migrating and can be overlooked in a census; in Russia, for example, many people don't know that the census of 2010 has taken place. The gender imbalance will probably increase in the future, because of gender-testing technologies and their increasing availability, and discrimination in care practices for girls.3,6
Due to migration, a regional excess of men can have global repercussions. The outflow of men can further stimulate gender-selective practices in their native countries. The increasing gender imbalance may require a revision of traditional patterns of sexual behaviour, including effective measures against gender-selective abortions. However, measures taken by individual countries might be insufficient - international efforts could be required.8 Unfortunately, for young males in some regions, the damage has already been done, and measures against gender imbalance in today's newborns won't help them.
A globalised mankind needs to eliminate the motives for high fertility and gender shifts, and protect and support childless elderly people, unwed mothers and families raising girls. Traditions favouring men as the inheritors and maintainers of lineage and posterity7 should be discouraged.
