👨‍👧‍👦 Household Income in ZIP Code 20171

Annual Household Income: $171,372

💡 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.

Example: A couple earning $40,000 and $30,000 together have a household income of $70,000. If that's in the middle of all local incomes, it's the value shown here.

📉 Poverty Rate in ZIP Code 20171

Estimated Rate: 3.6%

💡 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.

In ZIP Code 20171, households that rent: 8,151 (43.1%)

📊 What does the renter household percentage reveal about this ZIP Code?
Household Type Count Share
Renter-Occupied 8,151 43.1%
Owner-Occupied 10,772 56.9%

Definition: This is the percentage of households that rent their home rather than own it. It includes only occupied housing units.

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.

Example: If 65% of homes in an area are renter-occupied, it means 65 out of every 100 households rent their home.

Other renter households 4,861 59.6%
