Knox-
then why on the ministry of health's website does it state that the male to female ratio is listed as 1:1?
Infant mortality rate is different than birth rate. Infant mortality rate is the rate at which infants die per a set amount of births, not the rate of infants born.

Once again, I state that although more males may die, more must be born at birth.

You cannot use infant mortality rates to calculate population ratio.
