The Center for Neighborhood Technology (CNT) has produced a housing and transportation index (the "H&T Index"), something that has been advocated by Secretary of Housing and Urban Development (HUD) Shaun Donovan and Secretary of Transportation Ray LaHood. The concept is certainly worth support. Affordable housing and mobility are crucial to the well-being of everyone, which translates into a better quality of life, more jobs and economic growth. Surely, much of the internationally comparatively high standard of living enjoyed by so many middle and lower income households in the United States has resulted from inexpensive housing (often on the urban fringe) and the ability to access virtually all of the urban area by quick and affordable personal transportation.
CNT has developed an impressive website, with "tons" of data and maps that are both impressive and attractive. But for all of its superficial impressiveness, the H&T Index is subject to serious misinterpretation and suffers from methodological flaws that neutralize the usefulness of its affordability indices.
