Annual Household Income: $97,521

💡 What does Household Income mean?

Definition: This represents the middle value of all household incomes in the ZIP code — 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.

💡 What does the Poverty Rate represent?

Definition: The percentage of people in this area living below the federal poverty threshold.

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%.

Note: This statistic only includes people living in households; it does not count those in student housing, military barracks, or nursing homes.

Why it matters: Areas with a high share of renter households often have younger populations, higher mobility, and different housing needs compared to mostly owner-occupied areas.
