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

💡 What does the Poverty Rate represent?

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

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.
