In questions H20 through H26 on the 1990 census forms, we asked people to report their payments for selected housing costs, including utilities and fuels (H20); real estate taxes (H21); fire, hazard, and flood insurance on the property (H22); first mortgages, deeds of trust , contracts to purchase, or similar debts on the property (H23); second or junior mortgages or home equity loans (H24); and, in appropriate cases, condominium fees (H25) and mobile home costs (H26). Although we collected data separately for each of  these components, census tabulations show only the sum of the component costs. This bulletin focuses on monthly homeowner housing costs for single-family homes.
