What counts as my household size for benefits?

Your household size for benefits depends on who lives with you and shares food or income. The rules vary by program, but generally include your spouse, children, and parents or children you support.

Your household size depends on the benefit program you're applying for. The rules are not the same for all programs.

SNAP (Food Stamps)

For SNAP (the Supplemental Nutrition Assistance Program), your household usually includes:

  • You
  • Your spouse, if you're married and live together
  • Your children under 22 who live with you and aren't married
  • Your parents or grandparents you live with and support
  • Other relatives you live with and support

Your household does not include:

  • People who pay you rent and buy their own food
  • Children 22 or older
  • Adults who aren't related to you
  • A person in a different household, even if you're dating

Medicaid

For Medicaid, your household usually includes:

  • You
  • Your spouse
  • Your children
  • Sometimes your parents, depending on your state and age

The exact rules vary by state. Your state's Medicaid agency can tell you who counts as part of your household for Medicaid purposes.

Why it matters

Your household size affects:

  • Whether you qualify for benefits
  • How much money you can earn and still qualify
  • How much benefit you receive

For example, a household of 4 has a higher income limit than a household of 2.

What to do next

When you apply for benefits, you'll list everyone in your household. The agency will ask questions to confirm who counts. Be honest and complete—applying is free, and only the agency decides if you qualify.

If you're not sure, ask the benefits agency. They can explain the rules for your situation.

Frequently asked questions

Do my adult children count toward my household size?

It depends on their age and situation. For SNAP, unmarried children under 22 who live with you count. Children 22 or older do not, even if they live with you. For Medicaid, the rules are different and vary by state. Check with your state Medicaid agency.

If my partner and I aren't married, do we count as one household?

For SNAP, no. You're separate households unless you're married or have a legal domestic partnership. You each apply separately. For Medicaid, the rules vary by state.

Does a boarder or roommate count as part of my household?

No. A person who pays rent and buys their own food is not part of your household for SNAP. For Medicaid, tell your state agency about anyone else in your home to be sure.
