This study examined the effects of socio-demographic, travel-related and psychographic variables on travel expenditures. The travel expenditure categories examined include lodging, meals and restaurants, attractions and festivals, entertainment, shopping, transportation and total expenditures. The results of the study provide a more comprehensive and holistic picture in the search of travel expenditure patterns based on multiple independent variables. This study reveals that, among the three groups of variables examined, income and trip-related characteristics were the most influential variables affecting tourism expenditures. Discussions and implications are also provided based on the study results. Copyright © 2006 John Wiley & Sons, Ltd.
