Notes:

This series is a measure of expected inflation (on average) over the five-year period that begins five years from today.

This series is constructed as:
(((((1+((BC_10YEAR-TC_10YEAR)/100))^10)/((1+((BC_5YEAR-TC_5YEAR)/100))^5))^0.2)-1)*100

where BC10_YEAR, TC_10YEAR, BC_5YEAR, and TC_5YEAR are the 10 year and 5 year nominal and inflation adjusted Treasury securities. All of those are the actual series IDs in FRED.
