Using Gini decomposition to explore the multidimensionality of spatial dispersal for tourism promotion – the case of outgoing passengers in Queensland, Australia

ABSTRACT Visitor dispersal is critical in spreading tourism benefits to peripheral regions, with imbalances of visitors a problem for many tourism organisations that warrants better tools for analysis. Gini decomposition of the length of stay and expenditures was used to measure visitor dispersal based on survey data of international visitors (n = 819) departing from Brisbane International Airport. Biplot visualisation and stacked contribution bar charts revealed multiple dimensions of visitor traits influencing dispersal across eight subregions in Queensland and their complex offsetting or compounding dispersion/concentration effects. Our results suggest that including expenditure provides a more comprehensive understanding of dispersal, highlighting “high spend, short stay” visitors.
