factors could account for the difference in ratio of adult
men to women in the general population and among the adult
population? In other words, why are there more women than
men in the adult population, but fewer women in the overall
of the answer may have to do with information found in another
section is health.
ratio of women to men is a function of the ratio at birth
(how many girls and how many boys are born) AND the mortality
patterns (the things that cause death at various stages of
a man or woman's life). One of the factors, for example, could
be the life expectancy of men compared to that of women. Women
live longer than men (by an average of 4 years) in all regions
of the world -- a fact that affects the adult population but
not the younger population.
