The U.S. Census Bureau includes any individuals age 15 or older, regardless of whether they’re related. Household income includes what each of them earns, even if they don’t use their money to support the household. This might be the case with a 17-year-old who works a part-time job and uses the income purely for their own enjoyment. This income can be included, particularly at the state level. Many households consist of only one individual, without roommates or family members who reside with them. This constitutes a household, as well, and the nation’s average household income is usually less than its average family income because these single-person households are included.
Average Household Income vs. Median Household Income
“Average” household income is different from “median” household income. Half of all families have more than the country’s median, and half have less. A median figure is right in the middle. It includes households with no income at all. Median household income figures are most often used by the U.S. Census Bureau, and it has revised its calculations for arriving at these figures a few times over the years.
How Household Income Works
Household income determines eligibility for insurance through the Health Insurance Marketplace, for financial assistance programs, and for some tax benefits. The defining rules for household income can vary between entities and programs. For example, let’s say:
Joe lives alone, earning $35,000 annually.Josie and John live together, just the two of them, and they earn $70,000 jointly.Jackie and Janie live together and share their home with Jackie’s sibling. Their three incomes combined work out to $50,000.
The average of these three household incomes—about $51,667—works out to be slightly more than what the three-person household brings in. However, it is a good bit more than Joe’s household income or that of Jackie and Janie individually. Yet they’re all defined as household incomes for the purposes of calculating government benefits and other assistance programs.
The Health Insurance Marketplace
Purchasing health insurance through the Health Insurance Marketplace requires that you estimate your household income for the coming year, adding in all household members, including those who won’t need coverage. You can’t just use last year’s income. This marketplace determines your eligibility using modified adjusted gross income (MAGI), which is effectively your taxable income with certain tax deductions added back in.
The U.S. Census Bureau
The Census Bureau uses household income data to establish poverty status and guidelines for numerous federal purposes. It also determines the country’s poverty rate for legislative and documentation purposes. The Census Bureau does not include the incomes of household members who lived in the home at some point during the last year but no longer reside there at the time data is collected from the household. It does include the incomes of individuals who didn’t live in the residence during the past year but who might have moved in on the day of the interview.
Internal Revenue Service
The IRS uses every household member’s MAGI for determining eligibility for the premium tax credit, but only if the party is required to file a tax return by law. This depends on income thresholds, so very low earners are typically exempt. The IRS defines MAGI as the individual’s adjusted gross income plus sources of income that they were able to exclude to arrive at this number. This might be foreign income, Social Security benefits that wouldn’t normally be taxable, and tax-exempt interest. It does not include Supplemental Security income they might receive.
Supplemental Nutrition Assistance Program (SNAP)
SNAP, which used to be known as “food stamps,” measures household income in three ways to determine eligibility:
Gross monthly household income before any allowable deductions are madeNet household income after deductionsThe total value of a household’s assets that could potentially be sold to raise money for food
Deductions can be taken for must-pay household costs, such as rent and utilities, as well as for dependent care, child support, and out-of-pocket medical expenses for certain household members.
Types of Household Income
These rules encompass virtually all sources of income, earned and unearned, but some qualifying rules do apply to a few of them. The list of includable income is extensive. It breaks down like this for the most common programs, but other programs might have their own rules, particularly for more obscure sources of income. Furthermore, the Census Bureau includes financial assistance provided to a household by anyone who doesn’t live there, such as a friend or family member.
