Robert Marans was principal investigator of the 50th DAS, which built on questions posed in 1966, 1974, and 1980 to examine changes over time in the public’s perceptions of various aspects of community life, including transportation, recreation, housing, and residential mobility. The survey showed satisfaction declines in many categories, but a stable 83 percent of residents surveyed in Wayne, Oakland, and Macomb counties reported satisfaction with their lives as a whole. DAS 2001 differed from previous studies in that it expanded the survey to four additional metro counties. It also linked survey responses to contextual data from the U.S. Census and other sources using geographic information systems (GIS). Marans is currently working with international researchers to adapt the survey to local conditions that allow for cross-national comparisons.
