Census Tract Information for Tucson
"Census tracts are small, relatively permanent statistical subdivisions of a county. Census tracts are delineated for most metropolitan areas (MA's) and other densely populated counties by local census statistical areas committees following Census Bureau guidelines (more than 3,000 census tracts have been established in 221 counties outside MA's)."

Indicators of Neighborhood Stress:
"The Indicators of Neighborhood Stress documents are based on data from the 2000 Census of Population and Housing. They use a composite of 27 indicators of social dependency and housing need, and measure neighborhoods against the City of Tucson average and the Pima County average. The reports can be used as supporting information in target areas for housing rehabilitation and programs that address social needs."
