News release: “Most families with young children live within a mile of a public elementary school. The most common home heating fuel in the U.S. is gas. Only a third of American homes have a working carbon monoxide detector. These are just some of the findings of a comprehensive national sample of the more than 130 million residential housing units released today by the U.S. Department of Housing and Urban Development. HUD’s 2009 American Housing Survey (AHS) is the most thorough look inside the homes of millions of Americans and reveals everything from the square footage of the unit to how many homes have front porches, garages or even usable fireplaces. First conducted in 1973, the survey’s long-term design allows analysts to trace the characteristics of U.S. housing units and their occupants. For example, the 2009 survey reveals that significantly more American homes are larger and have more bedrooms and bathrooms than homes 37 years ago. In addition, homes of 1973 were significantly less likely to have central air conditioning and other amenities considered commonplace today.”
