Rent Burden in America: Counties Where Rent Exceeds 30% of Income
Nearly half of all American renters spend more than 30% of their income on housing, the threshold HUD defines as rent burdened. Using Fair Market Rent data and Census Bureau income estimates across more than 3,000 counties, we mapped where rent burden is most severe and what drives it.
The 30% Rule and Why It Matters
The 30% threshold has been a cornerstone of US housing policy since 1981, when Congress established it as the standard for affordable housing. The logic is straightforward: if a household spends more than 30% of gross income on rent and utilities, there is not enough left for food, transportation, healthcare, childcare, and savings. Households crossing this line face difficult tradeoffs that affect health, education, and economic mobility.
According to the National Low Income Housing Coalition's Out of Reach report, a full-time worker must earn over $25 per hour to afford a modest 2-bedroom rental at Fair Market Rent nationally. In many counties, the required wage exceeds $30 or even $40 per hour.
Where Rent Burden Is Worst
Our analysis of FMR-to-income ratios reveals two distinct patterns of severe rent burden. The first pattern appears in expensive coastal markets where high absolute rents overwhelm even moderate incomes. Counties in the Miami, Los Angeles, New York, and San Diego metro areas consistently show rent burden rates exceeding 50% among renters.
The second pattern appears in lower-income areas where rents are moderate in absolute terms but high relative to local wages. Parts of the Mississippi Delta, rural Appalachia, and the Rio Grande Valley have some of the highest rent burden rates in the country despite relatively low FMR levels.

Rent Burden by Income Level
Rent burden falls disproportionately on low-income households. Among renter households earning less than $25,000 per year, more than 80% are rent burdened and more than 70% are severely rent burdened (spending 50%+ of income on rent). Among households earning $50,000-75,000, the rate drops to about 25%. Above $75,000, fewer than 10% of renters are burdened.
This income gradient means that county-level rent burden rates are heavily influenced by the local income distribution. A county with many low-wage jobs will show high rent burden even if rents are below the national average. Our Fair Market Rent guide explains how HUD measures area affordability thresholds.
The Consequences of Rent Burden
Research from the Urban Institute and other organizations documents the cascading effects of rent burden. Rent-burdened households are more likely to skip meals, delay medical care, fall behind on utility bills, and experience housing instability. Children in rent-burdened households show lower academic achievement and higher rates of behavioral problems.
Severe rent burden is also the primary predictor of homelessness. Counties with high severe rent burden rates tend to have higher rates of homelessness, particularly among families with children. The connection between unaffordable rent and homelessness underscores the importance of housing assistance programs like Section 8 vouchers.
Finding More Affordable Markets
For renters facing severe rent burden, relocating to a more affordable county can dramatically improve financial wellbeing. Our most affordable counties ranking identifies markets where 2-bedroom FMR is under $700 per month. The county comparison tool lets you compare rent burden ratios side by side to evaluate potential moves.
Frequently Asked Questions
Rent burden is defined by HUD as spending more than 30% of gross household income on rent and utilities. Households spending 30-49% are considered rent burdened, while those spending 50% or more are severely rent burdened. Nationally, about 46% of renter households are rent burdened.
Counties with the highest rent burden tend to be in two categories: expensive coastal markets where rents are high (like Miami-Dade and Los Angeles), and lower-income areas where rents are moderate but incomes are very low (like parts of the Mississippi Delta and Appalachia). Both situations produce high rent-to-income ratios.
Rent burden is calculated by dividing gross monthly rent (including utilities) by gross monthly household income. If the result exceeds 30%, the household is rent burdened. HUD uses this threshold because spending more than 30% on housing leaves insufficient income for food, healthcare, transportation, and other necessities.
Options include applying for Section 8 Housing Choice Vouchers, exploring other rental assistance programs, considering roommates to split costs, relocating to a more affordable county, or negotiating rent with landlords. Our county comparison tool helps identify more affordable markets nearby.
