Comparison of the distributions of transport costs for the working population of London, New York and Sao Paulo.

The comparison is part of an investigation into the impacts of time, cost and transfer accessibilities on cities, classes and races by Bittencourt and Giannotti (2021). It uses the Gini coefficients, which measure the extent to which the distribution of transportation costs among individuals within a city deviates from a perfectly equal distribution. A Gini coefficient of 0 represents perfect equality, while a coefficient of 100 implies perfect inequality.
