The total fertility rate for the US is well below replacement levels. However, even this includes about 40% of births to unwed mothers, and 25% among White mothers. What is the fertility rate among non-Hispanic White women alone? I think it is pretty low.

Hey White girls:
The White Race has a long and glorious history, that you are a part of. Keep it going!
Don’t make any babies with Black or Hispanic men. Asians are not so bad, but it would be best if you stick with your White brothers.
White Babies please.
Get married first.
Get married young.
No sex before marriage. Get married young, and then have a lot of sex.
In the past, the primary way that young women got married was Family and Friends. Mostly, their Mom helped them find a husband.
Plan on being a Stay At Home Mom, and having a lot of babies, at least four before you turn 30.
You can stay at home and live with your father until you are married. Then, you don’t have to learn a trade, and can avoid any student debt. You should still educate yourself, because you will have to educate the next generation (your children) of the White Race, and White Americans.
Read lots of good books. Mostly, old ones, before 1910.
I recommend the eleven-volume Story of Civilization series, by Will Durant. Learn the history of the White Race.
No vaccines.
Breastfeeding only.
Homeschool.
Cook healthy food at home.
Not too much screen time. I recommend NO screens before Age 6. It is very tempting, but don’t do it.
Get together with the other young White moms, and let your children play together.
Forget about the other bitches. Don’t imitate them.
