What is housing cost burden?

Housing cost burden is a measure the Census Bureau uses for households that spend more than 30% of their income on housing: rent, mortgage and other housing needs. For an owner, the costs counted are mortgage principal and interest, real estate taxes, homeowner's insurance, utilities and, where they apply, mobile home costs, second mortgage payments and condominium fees; for a renter, monthly rent and utility bills.

It's a statistical line, not a rule: the Census Bureau uses it to count and compare households.

Where you’ll see the word

  • A Census Bureau report

    Its stories on renters and homeowners count the households above the 30% line, from the American Community Survey.

  • A county data table

    The American Community Survey's five-year estimates carry renter and owner cost-burden figures for every county, which is how the Bureau compares them.

What housing cost burden means for you

Who's in the count. The Census Bureau calculates housing cost ratios for renter-occupied units that pay cash rent and have positive household income; households with zero or negative income, and renters paying no cash rent, are left out of the calculations.

Renters show up more than owners. Census Bureau data show renters are more likely than homeowners to spend more than 30% of their income on housing costs, and among the lowest-income renters the ratios are far more variable than in higher-income groups. The Bureau notes that for low-income renter households, even a small change in rental costs can have a significant impact on their cost ratios.

Questions about housing cost burden

Which places have the most cost-burdened renters?

In the Census Bureau's county comparison from the 2017–2021 American Community Survey, more than half of renter households that paid rent and had income were cost burdened in a set of counties that includes some of the most populous, Harris County, Texas and Los Angeles County, California among them.

Is housing cost burden the same as shelter inflation?

No. Shelter inflation, on our shelter CPI page, tracks changes in rents and owners' equivalent rent; cost burden measures the share of income housing takes. Prices can rise while the burden share holds, if incomes keep pace, and the other way around.
