This is lengthy piece about marriage, but it contains insightful observations about modern homeschooling families and their fruitfulness:
I quote from a chunk:
"More importantly, however, these refunctionalized families also remake the very psychology of homes. They become beehives of activity: the evidence suggests that these families are more likely than nonhomeschooling households to live in semirural locations, tend a vegetable garden, engage in simple animal husbandry, create home businesses, and turn to home births.
And regarding that last item, homeschooling families are also rebuilding the bond of marriage by recovering procreative sexuality. One 1997 survey found 98 percent of homeschooling children to be living in married-couple households. The sexual division of labor in these homes was more pronounced: 52 percent of homeschoolers lived in two-parent families with only one parent in the workforce, compared to 19 percent of children nationwide.
And these families were noticeably larger: with nearly twice as many children as the national average. Indeed, 62 percent of homeschooling families have three or more children, compared to 20 percent nationwide; a third of these homes have four or more children, compared with only 6 percent nationwide. 'Functional' and 'prolific,' it appears, still go together, underscoring both the poetry and the power of that wonderful phrase, 'They become one flesh.' "
