Mortality Comparisons; The Male-Female Ratio,But male death rates at most ages are at least 50 percent higher than female rates. The ratio of male to female rates, simply averaged over the ages, may show males 80 percent higher; the average with living population as weights may show males 70 percent higher; with deaths as weights males may be
