These data come from the BLS Consumer Price Index program. To learn more, see "Consumer Price Index — November 2011" (HTML) (PDF), news release USDL-11-1748. The relative importance of a component is its expenditure or value weight expressed as a percentage. When the value weights are collected, they represent average annual expenditures, and their relative importance ratios show approximately how the index population distributes expenditures among the components.
