N2  - Household travel surveys have been conducted recently in a number of metropolitan areas. Metropolitan areas, travel behavior, and data processing capability have changed, requiring current data for analysis and planning; but nonresponse bias persists, often leading to a lack of adequate representation of low-income, low-education, and minority residents. A method to subdivide a study area geographically into microzones to account for the differences in return rates is suggested in conjunction with conventional factoring. In applying this basic step to data collected in suburban Chicago, the representation of families residing in selected areas increased markedly in contrast to factoring by standard techniques, yielding factored data that correspond to county-level data available from standard sources.
