One in 11 households has a net worth of a million dollars or more.

That’s without counting home equity.  Throw that in, you get to one household in 8 with net worth of a million dollars or more.

From here.

Very few of these ~15 million households (including home equity) or ~11 million (without home equity) are non-family or solo-parent family households.  They are something around 20% of all married households (with and without minor children at home).

Food for thought.
