The 1988/1989 Maricopa Household Travel Study was intended to document how residents use the streets, highways, and transit services in the Phoenix Metropolitan area. Respondents were asked to record their travel and activities for a 24-hour period. They were also asked for detailed information regarding their trips, including mode of transportation, trip purpose, departure and arrival times, and number of passengers. Demographic variables include gender, age, employment status, household size, number of children over five years old in the household, household income, and whether respondents had a valid drivers license at the time of the survey.

The original data deposit for this collection contained several discrepancies that could not be resolved due to a lack of documentation. Therefore, this collection has been minimally processed by ICPSR.

For additional information regarding this study, please refer to the Metropolitan Travel Survey Archive Web site.

The primary objectives of this study were to update the trip generation rates used in the Maricopa Association of Governments (MAG) travel demand forecasting process, and to provide data to validate the MAG trip distribution model.

A disproportionate stratified sample was utilized on this project. Using this procedure, the sample was stratified on the basis of household size and vehicle ownership and quotas were assigned to each strata. The base for the quota assignments was the trip making variability within each strata. During the pre-test segment of this project it was determined that with repeated call backs and travel day re-scheduling approximately 65 percent of those households which agreed to participate in this study would actually do so. With this in mind, screening quotas were assigned that took into account a non-participation rate.

2013-11-26 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Checked for undocumented or out-of-range codes.

The data contain two weight variables that users may wish to use in analysis: HHWGT (Household Weighting Factor) and PERWGT (Person Weighting Factor).


  • Data in this collection are available only to users at ICPSR member institutions.
