Abstract

This workshop resource paper reports on issues pertaining to item nonresponse in travel surveys. It presents a typology of item nonresponse errors, identifies missing data problems, and provides solutions for preventing and/or reducing data gaps at the item level. The authors conclude with recommendations for post-survey corrections to missing data, given the fact that it is impossible to achieve perfect, complete data in surveys.
