A review of the literature indicates that fairly simplistic measures of equality in travel distances are normally used in facility location studies. Two popular criteria, those of minimizing the maximal distance and the range, are known to be sensitive to the extreme values (locations of users) of the problem. This paper recommends that distributional equality should be used instead in most locational studies. Using a simple spatial setting, the paper offers a comparative analysis of equality curves based on the following measures: Gini coefficient, mean deviation, Hoover's concentration index, variance (standard deviation), and Theil's entropy index.
