Regional Price Parities (RPPs)
Spatial price indexes that reflect price level differences across regions for a specified time period: Temporal Price Indexes: across time for a specified region
Useful for comparing economic data, such as consumption expenditures and income levels: BEA currently does not adjust regional data for differences in price
levels across regions. RPPs are a first step in that direction.
RPPs are experimental estimates based on BLS and Census data.

Using RPPs to Adjust Data
Controls for differences in regional price levels:
Personal Income (PI), 2009(billions $)
State RPP Unadjusted PI
Adjusted PI
Alaska 108.1 30.2 28.0
Hawaii 118.5 54.6 46.1
Indiana 90.8 218.5 241.0
South Dakota 83.8 31.2 37.3
All States* 100.0 12,168.2
* Includes Washington, DC.
54.6 / 31.2 = 1.75 Unadjusted PI is 75% higher in Hawaii than in South Dakota.
After adjustment, PI is only 24% higher in Hawaii.

Balancing Factor (BF) Adjustment
Need arises due to distributional differences in data:-Small impact: 0.15% increase-BF may be unavailable: ex. average salaries by state-If so, simply divide by RPP/100 to adjust data
