Median and Average Household Incomes (HHI) often vary depending on the amount of high incoem earners in the area. The 25th and 75th percentiles give insight into the overall range of variation for the HHI across the Census Tracts of each market. Another good way to quantify variation can be with a Gini Coefficient, often from the view point of inequality. The values of Gini Coefficients could be classified as follows: Low (0 to .3), Moderate (.3 to .4), High (.4 to .6), Extreme (.6 to 1).
Disposable Income
Disposable income is defined here as Household Income after accounting for Federal, State, and Local taxes.
The lines on the following chart represent the corresponding reduction from HHI to Disposable HHI. Purple = 15% decrease, Blue = 25% decrease, Green = 35% decrease, Orange = 45% decrease, Red = 55% decrease

Discretionary Income
Discretionary income goes a step further. It takes Disposable Income, which already accounts for taxes, and accounts for the typical cost of Food, Housing, and Clothing.
The lines on the following chart represent the corresponding reduction from HHI to Discretionary HHI. Purple = 15% decrease, Blue = 25% decrease, Green = 35% decrease, Orange = 45% decrease, Red = 55% decrease
