NationMaster - Encyclopedia: Gender imbalance

Gender imbalance is a demographic effect that may arise either as a consequence of warfare (excess of females, notably in the wake of WWI in western Europe, and WWII, particularly in the Soviet Union) or of Sex-selective abortion and infanticide (excess of males, notably in mainland China as a result of the one-child policy, or in India). Gender imbalance may result in social unrest, especially in the case of an excess of young males unable to find a spouse. Wikipedia does not have an article with this exact name. ...

The natural sex ratio at conception is estimated close to 1.05 males/female (this is related to the weight ratio of X to Y chromosomes) ^{[citation needed]}. Due to the universally higher life expectancy of females, sex ratio tends to even out in adult population, and result in an excess of females among the elderly (e.g., the male to female ratio falls from 1.05 for the group aged 15 to 65 to 0.70 for the group over 65 in Germany, from 1.00 to 0.72 in the USA, from 1.06 to 0.91 in mainland China and from 1.07 to 1.02 in India).

Countries on the Arabian peninsula tend to have a 'natural' ratio of ca. 1.05 at birth but a very high rate of males for those over 65 (Saudi Arabia 1.13, Arab Emirates 2.73, Qatar 2.84), indicating an above average mortality of females. Conversely, countries of Eastern Europe (the Baltic states, Belorussia, Ukraine, Russia) tend to have a 'normal' ratio at birth but a very low rate of males for those over 65 (Russia 0.46, Lativa 0.48, Ukraine 0.52); similarly, Armenia has a far above average male rate at birth (1.17), and a below average male rate above 65 (0.67). This effect may be caused by emigration of males as well as by higher male mortality.
