regarding the stat redfin uses: homeownership" is only counting those that are head of household (which is who is responding when filling out a census), e.g. if there are ~100 genZ's, consisting of 96 that live with their parents, 3 that rent, 1 that owns their own home, the stat just takes those last two numbers, ~1/4, and redfin then reports "26% of GenZs owned their own home".
