8. Delaware: $2.31 billion

GOBankingRates ranked Delaware as one of the top states for single-parent families thanks to its high median household income and resources for low-income families, including Medicaid expansion. Still, Delaware is one of the states with the lowest welfare spending.

The low welfare spending could also be due to the state's low population. Delaware is the sixth-least-populated state — not including Washington, D.C. — with the Census Bureau estimating its 2016 population at 952,065.
