can you quantify the difference?
federal poverty level for a family of 2 - $16,020; $24,300 for a family of 4.
what i'd consider poor is harder to enumerate, but certainly would include households making substantially more than that. with farmers, it can be even harder to define since quite a few have very limited (and subject to substantial annual variation, which i think deserves a small discount) incomes but much greater net worth than would be typical for households with that income.
on a pure income basis, i'd probably put poor at somewhere around 40k for 2, 55k for 4. on a pure net worth basis, probably around 0k at 30 years, 650k at 65. however, for farmers i would also apply some sort of discount to the net worth, at least for farmers that live on their property. i'm not sure how much of a discount, but some. generating a definition that accounts for both income and net worth is beyond the scope of this post.
