As far as any of that being pro-abortion, it's not. Population statistics can certainly be misused to advocate for abortion, but you can use them to advocate for anything you want ~ like selling more bread, selling less meat, using fats, consuming sardines ~ you name it.
BTW, the conception ratios are exactly on the button.
Regarding early childbirth, that's always been a problem ~ everybody knows it. It's not an argument for abortion but rather a warning to the pedophiles to leave the young girls alone or you will be executed by the village elders faster than you can believe.
At the same time girls brought up under the rigors of heavy farm labor reach menses later ~ for what that's worth.
Your reference backward from lifestyle to birth ratios is BS. They are not linked and the higher level here is not universal. The world average is a 1:1 ratio ~ there are countries with more girls born than boys.
The adult ratio reflects conditions of life for each sex, on the average.
Now the relationship between Conservatives and Liberals is definitely skewed by actions taken at or before birth. Liberals kill their own kids at such a high rate that Conservatism in America is now demonstrably something that provides a family a biological advantage.
As you can see, the sex ratio at birth is higher to account for the higher death rate of males at all ages. Your claim is that women have the higher death rate.
Sex ratio: at birth: 1.07 male(s)/female
under 15 years: 1.07 male(s)/female
15-64 years: 1.02 male(s)/female
65 years and over: 0.79 male(s)/female
total population: 1.01 male(s)/female (2011 est.)
Definition: This entry includes the number of males for each female in five age groups - at birth, under 15 years, 15-64 years, 65 years and over, and for the total population. Sex ratio at birth has recently emerged as an indicator of certain kinds of sex discrimination in some countries. For instance, high sex ratios at birth in some Asian countries are now attributed to sex-selective abortion and infanticide due to a strong preference for sons. This will affect future marriage patterns and fertility patterns. Eventually, it could cause unrest among young adult males who are unable to find partners.
