👨‍👧‍👦 Household Income in ZIP Code 20191

Annual Household Income: $151,185

💡 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.

📉 Poverty Rate in ZIP Code 20191

Estimated Rate: 5.4%

💡 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.

🏘️ Renter vs. Owner Households in ZIP Code 20191

In ZIP Code 20191, households that rent: 3,895 (32%)

📊 What does the renter household percentage reveal about this ZIP Code?

Household Type	Count	Share
Renter-Occupied	3,895	32%
Owner-Occupied	8,268	68%

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.
