The number of home-schooled kids hit 1.5 million in 2007, up 74% from when the Department of Education's National Center for Education Statistics started keeping track in 1999, and up 36% since 2003. The percentage of the school-age population that was home-schooled increased from 2.2% in 2003 to 2.9% in 2007. 'There's no reason to believe it would not keep going up,' says Gail Mulligan, a statistician at the center."
Could be both. Home-schooled kids number almost 2 million, close to the number of prisoners in U.S. of part of A. jails, and We know what kind of money that population moves. It's been proven time and again that home-schooled kids do better in practically every measure of academic evaluations, so the growth in their numbers bodes well for the future of the country.
So if the mainstream media ignores it, does that matter? Seems to me it's far worse that state and national government agencies are making it more difficult to home-school, in which case, mainstream media silence is a problem.
