# §591.216. How does OPM combine survey data for the DC area and for COLA areas with multiple survey areas?

- (a) **Washington, DC, area.** For each survey item except shelter, OPM averages separately the prices collected in each of the DC survey areas identified in [§ 591.215(a)](/cfr/5/591.215.md?p=a) and then averages these average prices together using equal weights to compute an overall average by item for the DC area.
- (b) **COLA areas with multiple survey areas.** OPM computes weighted average indexes at the item, PEG, MEG, and/or overall level by using the corresponding indexes and Federal employment weights from each survey area within the COLA area.
