To do this, you will enter the median incomes and the Consumer Price Index (CPI) values and create a new attribute that is the median incomes in real dollars.

In a case table, enter the median incomes as one attribute, Income, and the CPI values in another attribute, CPI. Create a third attribute, RealIncome. Pick a year to adjust to and note the CPI of that year. (These instructions will proceed as if you were adjusting to 2001. Replace “177.1” with whatever the CPI value is for the year you are adjusting to.)

To report the real incomes, select the attribute, then Edit, Copy Attribute. You can then get and paste the values into a word processing document.
