This study demonstrates applicability of two distinct data sources for travel behavior research.
Questions relating to reverse-commuting are raised with respect to all working residents, and working
residents in low-income households located in Minneapolis.
Census of Population and Housing, 1990 Public Use Microdata Sample (PUMS) and the Twin Cities
Metropolitan Council Travel Behavior Inventory (TBI) provide details on aspects of commute and travel
patterns. Examining organization and methods of analysis appropriate to determining particular travelrelated
information presents a unique perspective on the advantages and shortcomings of each data set.
PUMS data provide detailed household and work-journey information. To answer reverse-commuting
questions posed in this study, we consider household income, worker occupation, state and Public Use
Microdata Area of employment, number of persons in each household, means of transportation used for
the journey to work, and work journey duration.
TBI data contain a wealth of information on both the work journey and other trips, but lack the depth of
socioeconomic data available in the PUMS file. The value of TBI data in responding to this series of
questions lies in the details about trip location and purpose.
