Since my last comment here did not seem to work I put it in a google document. This is a way to deep dive on where are the best places in the USA to raise a family with more than two kids: https://docs.google.com/document/d/1tq9rY1TCs49XHckWtzOowYz_xHXFnRpOZq8r0lE5JSQ/edit#heading=h.cywpygwwkhbl
I added them later in the thread as individual files and they appear to have worked.
