(a) Survey areas. Each COLA area has one survey area, except Hawaii County, HI, and the U.S. Virgin Islands COLA areas. Hawaii County has two survey areas: the Hilo area and the Kailua Kona/Waimea area. The U.S. Virgin Islands also has two survey areas: the Island of St. Croix and the Islands of St. Thomas and St. John. The Washington, DC, area has three survey areas: the District of Columbia, the Maryland suburbs of the District of Columbia, and the Virginia suburbs of the District of Columbia. OPM collects non-housing data throughout the survey area, and for selected items such as golf, snow skiing, and air travel, OPM collects non-housing data in additional geographic locations. OPM may collect housing data throughout the survey area or in specific housing data collection areas. The following table shows the survey areas:

(b) Rest of the State of Alaska COLA area. OPM may collect survey data onsite, use alternative indicators of relative living costs (e.g., price and cost information published by the University of Alaska), or both. If the use of alternative indicators would result in a COLA rate reduction, OPM will conduct onsite surveys in one or more locations in the Rest of the State of Alaska COLA area, before making a reduction, to ensure that the reduction is warranted.

(c) Determining Survey Coverage. To aid OPM in determining survey coverage, OPM may from time to time conduct surveys of Federal employees in the COLA areas and/or the Washington, DC, area to determine where employees shop and what they spend on certain goods or services and to collect other information related to the price surveys and the calculation of price indexes.
