Cincinnati Electricity Index
Some incorrect prices for electricity in the Cincinnati area were used in calculating index values from November 2015 through November 2017. Correct prices were used in calculating December 2017 index values. Past indexes computed using the incorrect prices are not being corrected, which may affect the interpretation of the December 2017 index value and percent changes relative to past values for the Cincinnati metropolitan area, the Midwest Census Region, and Midwest size class A cities. The effect on the national index values was negligible.
