I know one who works as a GS (Federal gov) who went to a dating site for the sole purpose to find a willing sperm donor so she could be a Mom.
This DC/Balt area has the highest % of unmarried women in the country.
I think many Hollywood women have pretty well set that example desiring the status of motherhood (think: baby bump) and then having children with absolutely no interest in marriage.
The geography of that single mother phenomenon is more related to the “Great Society” making a man in the home a disqualifier for benefit, and having ever more babies to derive benefits more profitable.
Those B-W corridor single mother women are not the success/career driven types targeted in this poll. Your GS is.
