Thanks. I didn’t realize there was a baby bust from ‘65 to ‘82. Those years roughly correspond to major acceleration of the women’s lib movement when women abandoned the home in droves to search for fulfillment in the men’s world of work. In the year 2000 census there was a 12 or 13 percent increase in the number of women staying home compared to 1990. I don’t know if that is due to more immigrants or to white American women. Even so white women aren’t having children like Hispanic women are. Hispanics still value family more so than Whitey. I know a lady (white) who has a daughter in college who isn’t going to have children because they are too much work.
And they're not really major. LDS are only 2% of the US population.
If you consider homeschoolers a "demographic group," I think they'd show higher-than ZPG fertility, too. But like the lDS, they're still a small minority.
But maybe in a couple of generations.... :o)
