Tax income is expressed according to three levels of observation: \- the unit of consumption; \- the household; \- the person. The interdecile ratio of tax income per person establishes the ratio between the highest per capita incomes and the lowest per capita incomes, removing on each side the 10 % of people with the most extreme incomes. This indicator measures the relative disparity between the highest and lowest tax revenues, without being distorted by the most extreme incomes. It therefore allows to study the disparities in income per person within an area, but also between the zones.
