Annual Household Income: $82,851

💡 What does Household Income mean?

Definition: This represents the middle value of all household incomes in this area — half of households earn less, and half earn more.

Includes: wages, salaries, self-employment income, Social Security, pensions, investments, unemployment, public assistance, and rental income.

Does NOT include: capital gains, non-cash benefits (like food stamps), or tax refunds.

Household = any group of people (or a single person) living in the same housing unit.

How it works: The threshold is a dollar amount set by the U.S. Census Bureau that varies by family size and age. If a household's income is below that level, everyone in it is included in this rate.

Example: In a town of 10,000 people, if 1,500 have incomes below the poverty line, the poverty rate is 15%.
