A lot of articles say that the male/female inbalance in Chinese population could become a severe problem for China in near future (more male than female). I am wondering if the difference of life expectancies for male and female (female lives longer than male) could reduce the problem to some degree. I guess there must be some scientists on population research here that can answer such question. Here shows some data I obtained from an accountable website for people interested in such problem to exercise the brain.
Sex ratio
at birth: 1.13 male(s)/female
under 15 years: 1.17 male(s)/female
15-64 years: 1.06 male(s)/female
65 years and over: 0.92 male(s)/female
total population: 1.06 male(s)/female (2011 est.)
Life expectancy at birth
total population: 74.84 years
male: 72.82 years
female: 77.11 years (2011 est.)
