My sister was the first person I know to homeschool in our area...that was in the early 1980’s.
Myself and other siblings followed her lead. At our son’s wedding about 5 years ago, there was a family photo and I counted 19 homeschooled kids in the photo (there were none who hadn’t been homeschooled) The homschooled included mine, my nieces and nephews, and their children (2nd generation homeschooling going on), and my DIL and one of my nieces husband were also homeschooled.
It exponentially grows, as parents teach children, and children teach their children.
We HS'd two kids....K-12....in SoCal and OK.
They both survived...and are productive tax payers.
