One of the surprising findings of the new census is that the ratio of old men to old women is evening out. From middle age on there are always more women than men, with the gap widening to about two-to-one by the time people are 85. However, older men are surviving at a higher rate than they used to.
Since 2000, the number of women 60 - 74 has increased by 29.2%. The number of men in that age rage increased by 35.2%
There will probably never be an equal ratio of old men to old women, but things do seem to be evening a bit.
My nominee for the cause: the declining smoking rate.
