Severe mortgage burden is defined as an owner-occupied household spending at least 50 percent of income on homeowner costs or having no income.

Gross rent includes average monthly cost of utilities (i.e., electricity, natural gas, water, sewer, and heating fuels).

Severe rent burden is defined as a renter household spending at least 50 percent of household income on gross rent or having no income.

Extremely low-income (ELI) is defined as those with incomes at or below the federal poverty level or 30% of area median income, whichever is greater. Very low-income (VLI) is defined as those with incomes at or below 50% of area median income, including ELI households. Affordability is based on the common standard that households should not spend more than 30% of their income on housing. Rental units are both "affordable and available" to renters in a specific income group if the gross rent meets the 30% affordability threshold and they are either available for rent or occupied by households with incomes at or below the defined income level.

Residential greenhouse gas emissions come from fossil fuel combustion in home energy use, as well as the use of products that emit ozone-depleting substances. Emissions are presented in millions of metric tons of carbon dioxide equivalent (CO₂e). Other greenhouse gases include methane and nitrous oxide.

Transitional age youth (TAY) are young people between 16 and 24 years of age who are in transition out of state custody or foster care. Survey results on TAY outcomes are based on a five-year cohort. At 17 years of age, respondents reported any experience of homelessness in their lifetime, while 19- and 21-year-old respondents reported experience of homelessness in the past two years. Homelessness is defined as having no regular or adequate place to live.

Data on new housing units authorized for construction are limited to privately-owned homes.

Vacation homes are identified by the Census Bureau as housing units for "seasonal, recreational, or occasional use."

A 2013 study from The Ohio State University found that the share of homes built before 1950 was the most important predictor of elevated blood lead levels (BLLs) in Ohio children under 6. Those homes predate the earliest laws in the United States restricting the use of lead paint in housing, which were enacted in the 1950s in some cities. Pre-1950 homes are also more likely to have chipped paint or lead-contaminated dust which can be ingested by young children. The use of lead paint in housing was finally banned nationally in 1978 by the Consumer Product Safety Commission. As such homes built between 1950 to 1979 are considered to pose moderate levels of risk to young children; homes built prior to 1950 are considered to be pose a greater risk.
