By nature males and females are born in approximately the same ratio. During paediatric age however, in childhood itself a female child has more immunity than a male child. A female child can fight the germs and diseases better than the male child. For this reason, there are more deaths among males as compared to the females during paediatric age. During wars, there are more men killed as compared to women.
More men die due to accidents and diseases than women.
The average life span of females is more than that of males, and at any given time one finds more widows in the world than widowers. India has more male population than female due to female foeticide and infanticide. India is one of the few countries, along with the other neighbouring countries, in which the female population is less than the male population. The reason lies in the high rate of female infanticide in India, and the fact that more than one million female foetuses are aborted every year in this country, after they are identified as females. If this evil practice is stopped, then India too will have more females as compared to males.
